Conversion of glucosinolates to isothiocyanates in humans after ingestion of cooked watercress. (1/243)

Isothiocyanates (ITCs), major constituents of cruciferous vegetables, can inhibit tumorigenesis in rodents by modulating the metabolism of carcinogens. ITCs that occur as glucosinolates are released by myrosinase-mediated hydrolysis when raw vegetables are chopped or chewed. However, because cruciferous vegetables are commonly consumed by humans after being cooked, it is important to examine whether dietary glucosinolates are converted to ITCs after cooked cruciferous vegetables in which myrosinase is deactivated have been consumed. This information is useful for evaluating the potential role of ITCs in cruciferous vegetables in the protection against human cancers. A urinary marker, based on a cyclocondensation product formed by the reaction of ITCs and their conjugates with 1,2-benzenedithiol, was used to quantify the uptake of dietary ITCs in humans. At breakfast and lunch, nine volunteers consumed a total of 350 g of cooked watercress in which the myrosinase activity was completely deactivated. On the basis of the analysis of ITCs in the cooked watercress upon adding exogenous myrosinase, the amount of glucosinolates ingested by each subject was estimated to be 475 micromol. The 24-h urine samples showed that the total urinary excretion of ITC conjugates in the subjects ranged from 5.6 to 34.8 micromol, corresponding to 1.2-7.3% of the total amount ingested. On the basis of our previous results that approximately 50% of dietary ITCs were excreted in the urine as conjugates, these values represent the minimal in vivo conversion of glucosinolates to ITCs. For purposes of comparison, we carried out a second experiment in which 150 g of uncooked watercress were consumed. The percentage of urinary ITC conjugates excreted in this study ranged from 17.2 to 77.7% of the total ingested ITCs. These results indicate that glucosinolates are converted to ITCs in humans after ingestion of cooked watercress, in which the myrosinase has been completely inactivated. The extent of conversion, however, is considerably less than that after ingesting uncooked vegetables. Furthermore, upon incubation of the cooked watercress juice with fresh human feces under anaerobic conditions, approximately 18% of glucosinolates was hydrolyzed to ITCs in 2 h. These results suggest that the microflora in the intestinal tract are a likely source for the hydrolysis of glucosinolates to ITCs in humans.  (+info)

An expressional system of human cytochrome P-450 CYP1A1 gene transcription. (2/243)

AIM: To explore an expressional system of human cytochrome P-450 CYP1A1 (CYP1A1) gene transcription. METHODS: The plasmid pMC 6.3 K containing human CYP1A1 promoter was transiently transfected into Hep G2 cells. The expression of chloramphenical acetyltransferase (CAT) reporter gene was detected by ELISA. RESULTS: Both the CAT expression and CYP1A1 activity increased with the concentrations of beta-naphthoflavone from 2.5 to 10 mumol.L-1. At 10 mumol.L-1 of beta-naphthoflavone, the levels of CAT and CYP1A1 were 94-fold and 2.8-fold those of the corresponding control, respectively. Using this method, the study of 8 glucosinolates with various side chains on the induction of CYP1A1 gene transcription showed that none of the parent glucosinolates increased CAT expression, whereas the breakdown products of indol-3-yl-methyl glucosinolate (glucobrassicin), rather than indole-3-carbinol, increased the CAT expression. CONCLUSION: The CYP1A1 gene transcriptional system was more reliable and sensitive.  (+info)

Glucosinolate genetics and the attraction of the aphid parasitoid Diaeretiella rapae to Brassica. (3/243)

The control of insect pests using parasitoids and carnivores has been successfully applied in protected cropping systems, orchards and forestry. Their success in annual field crops has been more limited due largely to the difficulties of attracting and maintaining a sufficient density of parasitoids in the crop before the levls of the insect herbivores become economically damaging. Parasitoids are known to be attracted to host-plant volatiles; thus, manipulating the host-plant chemistry may provide a means of enhancing the attraction of parasitoids to their prey. In this study we describe the differential attraction of the braconid wasp Diaeretiella rapae to two near-isogenic lines of Brassica oleracea which differ in a gene which alters the chemical structure of the isothiocyanates which are emitted following tissue damage. We demonstrate that, by enhancing the production of but-3-enyl isothiocyanate in B. oleracea and Brassica napus (oilseed rape), we can increase the attraction of D. rapae to these plants under standard field conditions.  (+info)

Purification and characterisation of epithiospecifier protein from Brassica napus: enzymic intramolecular sulphur addition within alkenyl thiohydroximates derived from alkenyl glucosinolate hydrolysis. (4/243)

Epithiospecifier protein (ESP), a ferrous ion dependent protein, has a potential role in regulating the release of elemental sulphur, nitriles, isothiocyanates and cyanoepithioalkanes from glucosinolates. Two classes of ESP polypeptides were purified with molecular masses of 39 and 35 kDa, and we show that the previously reported instability was conditionally dependent. The 39 kDa polypeptide was made up of two distinct isozymes (5.00, 5.14) whilst several were present for the 35 kDa form of ESP (5.40-5.66). An anti-ESP antibody reacted with both the 39 and 35 kDa ESP forms in Brassica napus and strongly with a polypeptide corresponding to the 35 kDa ESP form in Crambe abyssinica, but did not detect any ESP in Sinapis alba or Raphanus sativus. A cytochrome P-450 mediated iron dependent epoxidation type mechanism is suggested for ESP.  (+info)

Characterization of glucosinolate uptake by leaf protoplasts of Brassica napus. (5/243)

The uptake of radiolabeled p-hydroxybenzylglucosinolate (p-OHBG) by protoplasts isolated from leaves of Brassica napus was detected using silicone oil filtration technique. The uptake was pH-dependent with higher uptake rates at acidic pH. Imposition of a pH gradient (internal alkaline) across the plasma membrane resulted in a rapid uptake of p-OHBG, which was inhibited in the presence of carbonyl cyanide m-chlorophenylhydrazone, indicating that the uptake is dependent on a proton motive force. Dissipation of the internal positive membrane potential generated a small influx as compared with that seen for pH gradient (DeltapH). Kinetic studies demonstrated the presence of two uptake systems, a saturable and a linear component. The saturable kinetics indicated carrier-mediated translocation with a K(m) of 1.0 mm and a V(max) of 28.7 nmol/microl/h. The linear component had very low substrate affinity. The carrier-mediated transport had a temperature coefficient (Q(10)) of 1.8 +/- 0.2 in the temperature range from 4-30 degrees C. The uptake was against a concentration gradient and was sensitive to protonophores, uncouplers, H(+)-ATPase inhibitors, and the sulfhydryl group modifier p-chloromercuriphenylsulfonic acid. The carrier-mediated uptake system had high specificity for glucosinolates because glucosinolate degradation products, amino acids, sugars, or glutathione conjugates did not compete for p-OHBG uptake. Glucosinolates with different side chains were equally good competitors of p-OHBG uptake, which indicates that the uptake system has low specificity for the glucosinolate side chains. Our data provide the first evidence of an active transport of glucosinolates by a proton-coupled symporter in the plasma membrane of rape leaves.  (+info)

A glucosinolate mutant of Arabidopsis is thermosensitive and defective in cytosolic Hsp90 expression after heat stress. (6/243)

The TU8 mutant of Arabidopsis previously described to be deficient in glucosinolate metabolism and pathogen-induced auxin accumulation was found to be remarkably less tolerant upon exposure to elevated temperatures than wild-type plants. Although moderately increased temperature only affected shoot growth, exposure to severe heat stress led to a dramatic decay of mutant plants. By contrast, wild-type seedlings showed little or no damage under the same conditions. Analysis of different heat stress proteins (Hsps) in TU8 seedlings revealed that only expression of cytoplasmic Hsp90 was affected in these plants. Although Hsp90 was present under control conditions, its level declined in mutant plants at elevated temperatures. Northern-blot analysis indicated that the decrease in Hsp90 protein was accompanied with a reduction of hsp90 transcript levels. Transient expression of Hsp90 in mutant protoplasts increased their survival rate at higher temperatures to near equivalent that of wild-type protoplasts. These data suggest that the reduced level of Hsp90 in TU8 mutants may be the primary cause for the observed reduction in thermostability.  (+info)

Cytochrome P450 CYP79B2 from Arabidopsis catalyzes the conversion of tryptophan to indole-3-acetaldoxime, a precursor of indole glucosinolates and indole-3-acetic acid. (7/243)

Glucosinolates are natural plant products known as flavor compounds, cancer-preventing agents, and biopesticides. We report cloning and characterization of the cytochrome P450 CYP79B2 from Arabidopsis. Heterologous expression of CYP79B2 in Escherichia coli shows that CYP79B2 catalyzes the conversion of tryptophan to indole-3-acetaldoxime. Recombinant CYP79B2 has a K(m) of 21 microm and a V(max) of 7.78 nmol/h/ml culture. Inhibitor studies show that CYP79B2 is different from a previously described enzyme activity that converts tryptophan to indole-3-acetaldoxime (Ludwig-Muller, J. , and Hilgenberg, W. (1990) Phytochemistry, 29, 1397-1400). CYP79B2 is wound-inducible and expressed in leaves, stem, flowers, and roots, with the highest expression in roots. Arabidopsis overexpressing CYP79B2 has increased levels of indole glucosinolates, which strongly indicates that CYP79B2 is involved in indole glucosinolate biosynthesis. Our data show that oxime production by CYP79s is not restricted to those amino acids that are precursors for cyanogenic glucosides. Our data are consistent with the hypothesis that indole glucosinolates have evolved from cyanogenesis. Indole-3-acetaldoxime is a precursor of the plant hormone indole-3-acetic acid, which suggests that CYP79B2 might function in biosynthesis of indole-3-acetic acid. Identification of CYP79B2 provides an important tool for modification of the indole glucosinolate content to improve nutritional value and pest resistance.  (+info)

High resolution X-ray crystallography shows that ascorbate is a cofactor for myrosinase and substitutes for the function of the catalytic base. (8/243)

Myrosinase, an S-glycosidase, hydrolyzes plant anionic 1-thio-beta-d-glucosides (glucosinolates) considered part of the plant defense system. Although O-glycosidases are ubiquitous, myrosinase is the only known S-glycosidase. Its active site is very similar to that of retaining O-glycosidases, but one of the catalytic residues in O-glycosidases, a carboxylate residue functioning as the general base, is replaced by a glutamine residue. Myrosinase is strongly activated by ascorbic acid. Several binary and ternary complexes of myrosinase with different transition state analogues and ascorbic acid have been analyzed at high resolution by x-ray crystallography along with a 2-deoxy-2-fluoro-glucosyl enzyme intermediate. One of the inhibitors, d-gluconhydroximo-1,5-lactam, binds simultaneously with a sulfate ion to form a mimic of the enzyme-substrate complex. Ascorbate binds to a site distinct from the glucose binding site but overlapping with the aglycon binding site, suggesting that activation occurs at the second step of catalysis, i.e. hydrolysis of the glycosyl enzyme. A water molecule is placed perfectly for activation by ascorbate and for nucleophilic attack on the covalently trapped 2-fluoro-glucosyl-moiety. Activation of the hydrolysis of the glucosyl enzyme intermediate is further evidenced by the observation that ascorbate enhances the rate of reactivation of the 2-fluoro-glycosyl enzyme, leading to the conclusion that ascorbic acid substitutes for the catalytic base in myrosinase.  (+info)

In a previous transactivation screen, two Arabidopsis thaliana R2R3-MYB transcription factors, HAG2/MYB76 and HAG3/MYB29, along with the already characterized HAG1/MYB28, were identified as putative regulators of aliphatic glucosinolate biosynthesis. Molecular and biochemical characterization of HAG2/MYB76 and HAG3/MYB29 functions was performed using transformants with increased or repressed transcript levels. Real-time PCR assays, cotransformation assays and measurements of glucosinolate contents were used to assess the impact of both MYB factors on the steady-state level of glucosinolate biosynthetic genes and accumulation of aliphatic glucosinolates. Both HAG2/MYB76 and HAG3/MYB29 were shown to be positive regulators of aliphatic glucosinolate biosynthesis. Expression of promoter-beta-glucuronidase (GUS) fusions indicated GUS activities in both vegetative and generative organs, with distinct characteristics for each MYB factor. HAG1/MYB28, HAG2/MYB76 and HAG3/MYB29 reciprocally transactivated ...

Glucosinolates are Brassicaceae-specific secondary metabolites that act as crop protectants, flavor precursors and cancer-prevention agents, which shows strong evidences of anticarcinogentic, antioxidant and antimicrobial activities. MYB28, the R2R3-MYB28 transcription factor, directly activates genes involved in aliphatic glucosinolate biosynthesis. In this study, the MYB28 homology (BoaMYB28) was identified in Chinese kale (Brassica oleracea var. alboglabra Bailey). Analysis of the nucleotide sequence indicated that the cDNA of BoaMYB28 was 1257 bp with an ORF of 1020 bp. The deduced BoaMYB28 protein was a polypeptide of 339 amino acid with a putative molecular mass of 38 kDa and a pI of 6.87. Sequence homology and phylogenetic analysis showed that BoaMYB28 was most closely related to MYB28 homologs from the Brassicaceae family. The expression levels of BoaMYB28 varies across the tissues and developmental stages. BoaMYB28 transcript levels were higher in leaves and stems compared with those in

Nitrile-specifier proteins involved in glucosinolate hydrolysis in Arabidopsis thaliana | Read by QxMDNitrile-specifier proteins involved in glucosinolate hydrolysis in Arabidopsis thaliana | Read by QxMD
Glucosinolates are plant secondary metabolites present in Brassicaceae plants such as the model plant Arabidopsis thaliana. Intact glucosinolates are believed to be biologically inactive, whereas degradation products after hydrolysis have multiple roles in growth regulation and defense. The degradation of glucosinolates is catalyzed by thioglucosidases called myrosinases and leads by default to the formation of isothiocyanates. The interaction of a protein called epithiospecifier protein (ESP) with myrosinase diverts the reaction toward the production of epithionitriles or nitriles depending on the glucosinolate structure. Here we report the identification of a new group of nitrile-specifier proteins (AtNSPs) in A. thaliana able to generate nitriles in conjunction with myrosinase and a more detailed characterization of one member (AtNSP2). Recombinant AtNSP2 expressed in Escherichia coli was used to test its impact on the outcome of glucosinolate hydrolysis using a gas chromatography-mass ...

Within the cell, biosynthetic pathways are embedded in protein-protein interaction networks. In Arabidopsis, the biosynthetic pathways of aliphatic and indole glucosinolate defense compounds are well-characterized. However, little is known about the spatial orchestration of these enzymes and their interplay with the cellular environment. To address these aspects, we applied two complementary, untargeted approaches - split-ubiquitin yeast 2-hybrid and co-immunoprecipitation screens - to identify proteins interacting with CYP83A1 and CYP83B1, two homologous enzymes specific for aliphatic and indole glucosinolate biosynthesis, respectively. Our analyses reveal distinct functional networks with substantial interconnection among the identified interactors for both pathway-specific markers, and add to our knowledge about how biochemical pathways are connected to cellular processes. Specifically, a group of protein interactors involved in cell death and the hypersensitive response provides a potential link

The ecological genetics of aliphatic glucosinolates. - Oxford Big Data InstituteThe ecological genetics of aliphatic glucosinolates. - Oxford Big Data Institute
Glucosinolates are plant secondary metabolites composed of a thioglucose group and an amino acid side-chain. They occur in the Brassicaceae and related families. A wide variety of glucosinolates exists owing to modification of the side-chain structure. Following tissue damage, myrosinase enzymes catalyse the decomposition of glucosinolates to a variety of volatile and nonvolatile products. The genetic control of concentration and side-chain modification of aliphatic glucosinolates, which have side-chains derived from methionine, are simple and well known from work on Arabidopsis and Brassica crops. In controlled conditions in the laboratory or in field trials, many aliphatic glucosinolates, or their degradation products, affect the behaviour of herbivores. For these reasons, we suggest that polymorphism for aliphatic glucosinolates in natural populations offers an attractive system for the study of ecological genetics of plant-herbivore interactions.

Chemoprotective Glucosinolates and Isothiocyanates of Broccoli Sprouts | Cancer Epidemiology, Biomarkers & PreventionChemoprotective Glucosinolates and Isothiocyanates of Broccoli Sprouts | Cancer Epidemiology, Biomarkers & Prevention
In previous clinical studies, we evaluated the metabolism and disposition of glucosinolates and isothiocyanates in a variety of crucifers, including market stage broccoli (11) . The current studies focus entirely on broccoli sprouts, which differ from mature broccoli plants in two important aspects (9 , 13 , 25) : (a) on a gram-fresh-weight basis, they contain up to 50 times more glucoraphanin, the glucosinolate precursor of sulforaphane, which is the most potent natural phase 2 enzyme-inducer known. Second, they contain substantially less or no detectable amounts of the indole and β-hydroxyalkenyl glucosinolates that are associated with potential toxicities (Table 1⇓ and Fig. 3⇓ ).. The principal end point in these studies was urinary dithiocarbamate excretion, as measured by the cyclocondensation reaction. Although this assay detects with equal efficiency isothiocyanates and each of the sequential metabolites (Fig. 1B)⇓ , the available evidence indicates that urine contains no ...

Cruciferous vegetables differ from other classes of vegetables in that they are rich sources of sulfur-containing compounds known as glucosinolates (see Cruciferous Vegetables). Because epidemiological studies provide some evidence that diets rich in cruciferous vegetables are associated with lower risk of several types of cancer, scientists are interested in the potential cancer-preventive activities of compounds derived from glucosinolates (1). Among these compounds is indole-3-carbinol (I3C), a compound derived from the enzymatic hydrolysis (breakdown) of an indole glucosinolate, commonly known as glucobrassicin (2).. Summary. * Indole-3-carbinol (I3C) is derived from the hydrolysis (breakdown) of glucobrassicin, a compound found in cruciferous vegetables. * In the acidic environment of the stomach, I3C molecules can combine with each other to form a number of biologically active acid condensation products, such as 3,3-diindolylmethane (DIM). * I3C has been found to inhibit the development ...

Glucosinolates are a group of sulfur-containing glycosides found in many plant species, including cruciferous vegetables such as broccoli, cabbage, brussels sprouts, and cauliflower. Accumulating evidence increasingly supports the beneficial effects of dietary glucosinolates on overall health, including as potential anti-cancer agents, because of their role in the prevention of the initiation of carcinogenesis via the induction of cellular defense detoxifying/antioxidant enzymes and their epigenetic mechanisms, including modification of the CpG methylation of cancer-related genes, histone modification regulation and changes in the expression of miRNAs. In this context, the defense mechanism mediated by Nrf2-antioxidative stress and anti-inflammatory signaling pathways can contribute to cellular protection against oxidative stress and reactive metabolites of carcinogens. In this review, we summarize the cancer chemopreventive role of naturally occurring glucosinolate derivatives as inhibitors of ...

Department of Plant Science and Agricultural Engineering, Universidade de Tras-os-Montes e Alto Douro, Apartado 1013, 5001-911 Vila Real, Portugal.. Broccoli inflorescences have been recognized as components of healthy diets on the basis of their high content of fiber, vitamin C, carotenoids, and glucosinolates/isothiocyanates. Broccoli sprouts have been recently shown to have high levels of glucoraphanin (4-methylsulfinylbutyl glucosinolate), the precursor of the chemoprotective isothiocyanate, sulforaphane. This study evaluated the effects of temperature and developmental stage on the glucosinolate content of broccoli sprouts. Seedlings cultivated using a 30/15 degrees C (day/night) temperature regime had significantly higher glucosinolate levels (measured at six consecutive days postemergence) than did sprouts cultivated at lower temperatures (22/15 and 18/12 degrees C; p , 0.001). Both higher (33.1 degrees C) and lower (11.3 degrees C) constant temperatures induced higher glucosinolate ...

These myrosinases are known to be encoded by at least two different families of myrosinase genes, denoted MA and MB. In the work described in this paper the presence of different myrosinase isoenzymes in embryos, seedlings, and vegetative mature tissues of B. napus was studied and related to the expression of myrosinase MA and MB genes in the same tissues to facilitate future functional studies of these enzymes. In developing seeds, myrosinases of 75, 73, 70, 68, 66, and 65 kD were present.

The aim of this study is to examine the effects of a diet rich in broccoli on cardiovascular disease risk using biochemical indicators such as blood lipid profiles, most notably cholesterol; markers of inflammation as well as established physiological measurements such as Pulse wave velocity (PWV), Augmentation index (AIx) and Ambulatory Blood Pressure Measurements (ABPM). Broccoli contains compounds known as glucosinolates which are metabolised to isothiocyanates when consumed. The major glucosinolate in broccoli is known as glucoraphanin which produces the isothiocyanate sulforaphane. The glucosinolates are thought to be the principal component in broccoli that may reduce CVD risk. The investigators will use a standard cultivar of broccoli and a cultivar that has enhanced levels of glucosinolates (HG broccoli). This broccoli has been used in previous intervention studies (e.g. ClinicalTrials.gov NCT00535977). Volunteers will be asked to consume 400g of standard broccoli, HG broccoli or peas ...

Myrosinase - WikipediaMyrosinase - Wikipedia
Myrosinase (EC 3.2.1.147, thioglucoside glucohydrolase, sinigrinase, and sinigrase) is a family of enzymes involved in plant defense against herbivores. The three-dimensional structure has been elucidated and is available in the PDB (see links in the infobox). A member of the glycoside hydrolase family, myrosinase possesses several similarities with the more ubiquitous O-glycosidases. However, myrosinase is the only known enzyme found in nature that can cleave a thio-linked glucose. Its known biological function is to catalyze the hydrolysis of a class of compounds called glucosinolates. Myrosinase is regarded as a defense-related enzyme and is capable of hydrolyzing glucosinolates into various compounds, some of which are toxic. Myrosinase catalyzes the chemical reaction a thioglucoside + H2O ⇌ {\displaystyle \rightleftharpoons } a sugar + a thiol Thus, the two substrates of this enzyme are thioglucoside and H2O, whereas its two products are sugar and thiol.

What else does kale have in it? Yep. You guessed it - glucosinolates. Now, I am sure everyone knows the deal with glucosinolates….What? You mean you dont??? Well, let me hit you with some knowledge!. Glucosinolates are compounds found in high concentrations in leafy green vegetables (especially kale). These molecules are especially cool because they activate the bodys own antioxidant system. This cascade of antioxidant activity actually cycles over and over within the body and continues to protect your system as many as 3 to 4 days after the glucosinolate-containing food has been consumed. Talk about protection! By this process, glucosinolates help the liver eliminate toxic molecules.. These toxins come from many sources: cigarette smoke, pollution, drugs, even free radicals generated by our own bodies in response to illness. So the big picture here is even if you eat super clean, it is good to have some kale in your diet to protect against the bad stuff that may be floating around in your ...

In order to successfully feed on a plant, herbivores need to overcome the chemical substances the plant produces to defend itself. One group of these defensive compounds is the glucosinolates, which are produced by all species of cruciferous vegetables, including cabbage, broccoli and horseradish, but also by the model plant Arabidopsis thaliana. Glucosinolates are easily converted into toxic isothiocyanates. Some herbivores deploy mechanisms to prevent the formation of isothiocyanates. Among them is the diamondback moth Plutella xylostella, a major agricultural pest that specializes on cabbage and related plant species. Repeated mass outbreaks have made this herbivore an economically important pest of vegetables worldwide. A group of scientists from the Department of Biochemistry at the Max Planck Institute for Chemical Ecology in Jena, Germany, and the Indian Institute of Science Education and Research in Pune, India, wanted to find out whether the enzymatic transformation of glucosinolates is ...

The aphid Brevicoryne brassicae is a specialist feeding on Brassicaceae plants. The insect has an intricate defence system involving a beta-D-thioglucosidase (myrosinase) that hydrolyses glucosinolates sequestered from the host plant into volatile isothiocyanates. These isothiocyanates act synergistically with the pheromone E-beta-farnesene to form an alarm system when the aphid is predated. In order to investigate the enzymatic characteristics of the aphid myrosinase and its three-dimensional structure, milligram amounts of pure recombinant aphid myrosinase were obtained from Echerichia coli. The recombinant enzyme had similar physiochemical properties to the native enzyme. The global structure is very similar to Sinapis alba myrosinase and plant beta-O-glucosidases. Aphid myrosinase has two catalytic glutamic acid residues positioned as in plant beta-O-glucosidases, and it is not obvious why this unusual enzyme hydrolyses glucosinolates, the common substrates of plant myrosinases which are ...

Glucosinolate - WikipediaGlucosinolate - Wikipedia
Glucosinolates and their products have a negative effect on many insects, resulting from a combination of deterrence and toxicity. In an attempt to apply this principle in an agronomic context, some glucosinolate-derived products can serve as antifeedants, i.e., natural pesticides.[15]. In contrast, the diamondback moth, a pest of cruciferous plants, may recognize the presence of glucosinolates, allowing it to identify the proper host plant.[16] Indeed, a characteristic, specialised insect fauna is found on glucosinolate-containing plants, including butterflies, such as large white, small white, and orange tip, but also certain aphids, moths, such as the southern armyworm, sawflies, and flea beetles.[citation needed] For instance, the large white butterfly deposits its eggs on these glucosinolate-containing plants, and the larvae survive even with high levels of glucosinolates and eat plant material containing glucosinolates.[citation needed] The whites and orange tips all possess the so-called ...

Cabbage has long been known as a fantastic food for the reduction of cancer risk, and for the healing of the intestinal tract. It turns out that there are numerous factors that play into those abilities. These include the beneficial fibers in cabbage, the content of glutamine (an amino acid-like substance used by intestinal cells for healing), and a high content of miraculous compounds called glucosinolates. Glucosinolates are sulfur containing molecules that have glucose attached to them. When you break open the cell walls of cabbage, an enzyme is released called myrosinase that removes the glucose from the sulfur compounds commonly called isothiocyanates. One of these isothiocyanates, sulforaphane, has an amazing capacity to turn on a part of our genes called the Antioxidant Response Element. When it does this, we start producing more antioxidant proteins, and detoxification proteins (enzymes actually) that provide us 72 hours of protection from environmentally and internally produced toxins. ...

ABSTRACT: Flavin monooxygenase (FMO) is one of the most important enzymes involved in glucosinolate biosynthesis. In this study, the full length of FMO gene (RsFMOgs-ox1) encoding a putative FMO protein composed of 450 amino acids was successfully cloned using the RACE-PCR method. The amino acid sequence of RsFMOgs-ox1 has high similarities of 92% and 83% with BrFMOgs-ox1 and AtFMOgs-ox1,2,3, respectively, and the gene structure of FMOgs-ox1 is similar to its plant homologues. Quantitative (qPCR) analysis revealed that RsFMOgs-ox1 was highly expressed during early seedling development. In mature radish, the highest expression was observed in the leaves, while the lowest transcript was evident in the root. The expression of RsFMOgs-ox1 was also regulated by wounding, notably 1 day after treatment. Subcellular localization in Arabidopsis showed that RsFMOgs-ox1 was localized in the cytoplasm and nuclei. This study allows us to understand something about RsFMOgs-ox1 function in glucosinolate ...

Broccoli, cabbage, and cauliflower have a chemical component called indole-3-carbinol that can combat breast cancer by converting a cancer-promoting estrogen into a more protective variety. Broccoli, especially sprouts, also have the phytochemical sulforaphane, a product of glucoraphanin - believed to aid in preventing some types of cancer, like colon and rectal cancer. Sulforaphane induces the production of certain enzymes that can deactivate free radicals and carcinogens. The enzymes have been shown to inhibit the growth of tumors in laboratory animals. However, be aware that the Agriculture Department studied 71 types of broccoli plants and found a 30-fold difference in the amounts of glucoraphanin.

Citation: N/A Interpretive Summary: Technical Abstract: The crucifer family, Brassicaceae, is an economically important family for its many food crops. Crucifers are characterized by the presence of a group of secondary compounds called glucosinolates, which with their degradation products are primarily responsible for the characteristic aromas and flavors of crucifers. Glucosinolate degradation products include substituted isothiocyanates, nitriles, thiocyanates, epithionitriles and oxazolidinethiones, which vary depending on the plant species studied, side-chain substitution, cell pH and cell iron concentration. Many of these degradation products have biological activity ranging from insect attractants to suspected human health benefits, but are not commercially available. We have developed methods for isolation and purification of several of these degradation products, including the isothiocyanates erucin, iberin, cheirolin, hesperin, and lesquerellin (as well as most of the corresponding ...

Glucosinolates (GSLs) are a class of secondary metabolites with allelochemical properties found in members of the Brassicales. GSLs are relatively nontoxic, but after hydrolysis of the sugar moiety by myrosinase (thioglucosidase), the compounds are degraded. The break-down products are highly bioactive, affect germination, growth of neighboring plants and can have antimicrobial effects. Therefore, the GSL/myrosinase complex is a natural plant defense system against diverse pathogens, which has already been used in integrated pest and weed management. Presently, potential negative long-term effects of the GSL hydrolysis products on beneficial soil microorganisms are not known. Bioassays performed in this study are based on analyzing growth suppression of selected pathogenic and beneficial soil fungi by GSLs and their hydrolysis products. Lipid, protein, enzyme and RNA analyses were carried out to systematically characterize GSL derived changes of the soil community structure. On this end, soil of ...

With increased heart rate, elevated production of ROS will appear. Indeed, this is thought to contribute to contractile and endothelial dysfunction, extracellular remodeling of the heart, and myocyte apoptosis. Furthermore, two molecular antioxidant processes are involved; the first one is redox-active and short-lived; it can also contribute to ROS production. On the other hand, the second one involves indirect antioxidants action; its long-lived and does not have a pro-oxidant effect. Therefore, the introduction of health-promoting antioxidant foods is needed to decrease the risk of CVD.. Sulforaphane is a metabolite of glucoraphanin (Grn), which in turn is the main glucosinolate (GLS) in broccoli. The production of sulforaphane is only possible when this is released due to plat injury. For example, chewing will chemically change the structure of glucoraphanin in conjunction with the enzyme myrosinase. Furthermore, this action will release glucose and sulfate, leaving the sulforaphane (SFN) ...

Isothiocyanates and their naturally occurring glucosinolate precursors are widely consumed as part of a diet rich in cruciferous vegetables. When plant cells are damaged, glucosinolates are released and converted to isothiocyanates by the enzyme myrosinase. Many isothiocyanates inhibit the neoplastic effects of various carcinogens at a number of organ sites. Consequently, these agents are attracting attention as potential chemoprotectors against cancer. As a prerequisite to understanding the mechanism of the protective effects of these compounds, which is thought to involve the modulation of carcinogen metabolism by the induction of phase 2 detoxication enzymes and the inhibition of phase 1 carcinogen-activating enzymes, we examined the fate of ingested isothiocyanates and glucosinolates in humans. Recently developed novel methods for quantifying isothiocyanates (and glucosinolates after their quantitative conversion to isothiocyanates by purified myrosinase) and their urinary metabolites ...

Isothiocyanates | ENCOGNITIVE.COMIsothiocyanates | ENCOGNITIVE.COM
Cruciferous vegetables, such as broccoli, cabbage and kale, are rich sources of sulfur-containing compounds called glucosinolates. Isothiocyanates are biologically active hydrolysis (breakdown) products of glucosinolates. Cruciferous vegetables contain a variety of different glucosinolates, each of which forms a different isothiocyanate when hydrolyzed (see Figure) (1). For example, broccoli is a good source of glucoraphanin, the glucosinolate precursor of sulforaphane (SFN), and sinigrin, the glucosinolate precursor of allyl isothiocyanate (AITC) (2). Watercress is a rich source of gluconasturtiin, the precursor of phenethyl isothiocyanate (PEITC), while garden cress is rich in glucotropaeolin, the precursor of benzyl isothiocyanate (BITC). At present, scientists are interested in the cancer-preventive activities of vegetables that are rich in glucosinolates (see Cruciferous Vegetables), as well as individual isothiocyanates (3).. Summary. * Isothiocyanates are derived from the hydrolysis ...

Effects of novel processing techniques on glucosinolates and membrane associated myrosinases in broccoliEffects of novel processing techniques on glucosinolates and membrane associated myrosinases in broccoli
High pressure/high temperature (HP/HT) and pulsed electric field (PEF) treatment of food are among the novel processing techniques considered as alternatives to conventional thermal food processing. Introduction of new processing techniques with fast and gentle processing steps may reveal new possibilities for preservation of healthy bioactive compounds in processed food. However, effects on various food components due to autolysis and fast reactions prior to the applied HP/HT or PEF need to be considered as the total contribution of processing steps affects the obtained food quality. The present experiments were performed on broccoli (Brassica oleracea var. Italica) florets, puree and juice. Specific focus was given to effects of HP/HT and PEF processing on the content of glucosinolates and activities of myrosinase isoenzymes (EC.3.2.1.147) in the broccoli preparations. Certain conditions applied in HP/HT processing of broccoli florets were able to maintain a high level of intact ...

The glucosinolate-myrosinase system is a well-known defense system that has been shown to induce stomatal closure in Brassicales. Isothiocyanates are highly reactive hydrolysates of glucosinolates, and an isothiocyanate, allyl isothiocyanate (AITC), induces stomatal closure accompanied by elevation of free cytosolic Ca2+ concentration ([Ca2+](cyt)) in Arabidopsis. It remains unknown whether AITC inhibits light-induced stomatal opening. This study investigated the role of Ca2+ in AITC-induced stomatal closure and inhibition of light-induced stomatal opening. AITC induced stomatal closure and inhibited light-induced stomatal opening in a dose-dependent manner. A Ca2+ channel inhibitor, La3+, a Ca(2+)chelator, EGTA, and an inhibitor of Ca2+ release from internal stores, nicotinamide, inhibited AITC-induced [Ca2+](cyt) elevation and stomatal closure, but did not affect inhibition of light-induced stomatal opening. AITC activated non-selective Ca2+-permeable cation channels and inhibited ...

Glucosinolates Determination in Tissues of Horseradish Plant -BIO-PROTOCOLGlucosinolates Determination in Tissues of Horseradish Plant -BIO-PROTOCOL
Glucosinolates (GLS) are secondary metabolites mainly found in plants belonging to the Brassicaceae family, including also horseradish (Armoracia rusticana G. Gaertn., B. Mey. & Scherb), a popular spice with a characteristic pungent flavor due to the abundance of GLS. Such compounds exhibit antibacterial, antifungal, and insecticidal activities, as well as human health properties. Therefore, it is very important to have a full understanding of their levels and profiles in plants. However, the characterization of GLS from horseradish crude extracts is a tough task, due to the complexity of the vegetal matrix and the occurrence of many GLS in trace amounts. Here we describe two alternative effective and rapid methods for GLS characterization in horseradish plants: Liquid chromatography coupled to high resolution mass spectrometry (LC-MS) for determination of intact GLS and HPLC-UV for determination of desulfo-GLS.

DIGITAL.CSIC: Effects of Stir-Fry Cooking with Different Edible Oils on the Phytochemical Composition of BroccoliDIGITAL.CSIC: Effects of Stir-Fry Cooking with Different Edible Oils on the Phytochemical Composition of Broccoli
Numerous epidemiological studies indicate that Brassica vegetables in general and broccoli in particular protect humans against cancer; they are rich sources of glucosinolates and posses a high content on flavonoids, vitamins, and mineral nutrients. The contents of total intact glucosinolates, total phenolics, vitamin C, and minerals (potassium, sodium, calcium, magnesium, iron, manganese, zinc, and copper) in the edible portions of freshly harvested broccoli (florets), which was subjected to stir-frying treatments, were evaluated. In the present work, the stir-fry cooking experiments were carried out using different edible oils from plant origin (refined olive oil, extra virgin olive oil, sunflower oil, peanut oil, soyabean oil, and safflower oil) known and used worldwide. Results showed that during stir-frying, phenolics and vitamin C were more affected than glucosinolates and minerals. Stir-fry cooking with extra virgin olive, soybean, peanut, or safflower oil did not reduce the total ...

Analysis of flavor precursors in radish and radish color extractsAnalysis of flavor precursors in radish and radish color extracts
Radish anthocyanin extract has potential as a natural colorant because of its pigment stability and attractive red hue. Presence of undesirable aroma compounds could limit its applications in foods. The pungent principle of radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG), and undergoes subsequent degradation to produce a number of volatiles. To evaluate the potential of flavor formation, juices were prepared from winter and spring radish cultivars. Whole radishes, peels and flesh, as well as radish extracts, were analyzed for glucosinolates and isothiocyanates. Aroma intensities of radish juice extracts were evaluated using sensory analysis. MTBI was monitored by HPLC (detection level 160 ppb). MTBG was extracted from freeze-dried radish tissue with boiling methanol, purified by anion exchange and enzymatically desulfated. DesulfoMTBG was quantified by HPLC, using ...

In the current study, we demonstrated that glucoraphanin, a stable precursor of the Nrf2 inducer sulforaphane, mitigated HFD-induced weight gain, insulin resistance, hepatic steatosis, oxidative stress, and chronic inflammation in mice. The weight-reducing and insulin-sensitizing effects of glucoraphanin were abolished in Nrf2−/− mice. Additionally, glucoraphanin lowered plasma LPS levels in HFD-fed mice and decreased the relative abundance of Desulfovibrionaceae. At the molecular level, glucoraphanin increased Ucp1 protein expression in WAT depots while suppressing the hepatic mRNA expression of genes involved in lipogenesis, NADPH oxidase, and inflammatory cytokines. The data suggest that in diet-induced obese mice, glucoraphanin restores energy expenditure and limits gut-derived metabolic endotoxemia, thereby preventing hepatic steatosis, insulin resistance, and chronic inflammation.. Consistent with previous reports demonstrating the antiobesity effects of synthetic Nrf2 inducers (9-11), ...

Isothiocyanates are naturally occurring small molecules that are formed from glucosinolate precursors of cruciferous vegetables. Many isothiocyanates, both natural and synthetic, display anticarcinogenic activity because they reduce activation of carcinogens and increase their detoxification. Recent studies show that they exhibit anti-tumor activity. Moreover, this work focused on the mitochondrial pathway. Cells were incubated with isothiocyanates concentrations, 50µM/L, 70µM/L, 90µM/L and 120µM/L for 72h at 37°C and 5%CO2. Isothiocyanates induced cells death in a dose-dependent manner. Isothiocyanates treated cells had an antiproliferative effect, additionally, a typical characteristics of apoptosis as: DNA fragmentation, caspase-3 over expression and fall of mitochondrial membrane potential by Bcl-2 expression down regulating, p53 activation as signal for cell cycle arrest and cytological alterations.

Epidemiological data indicate that dietary consumption of cruciferous vegetables may reduce the risk of many cancers including breast cancer. Cruciferous vegetables contain high levels of glucosinolates; stable phytochemicals that when metabolized produce cancer-preventing active isothiocyanates. Isothiocyanates, such as sulforaphane (SFN) found in broccoli sprouts, are thought to prevent tumorigenesis through epigenetic mechanisms controlling the expression of tumor-related genes. Ingestion of broccoli sprouts results in rapid distribution of SFN to breast epithelium, however, the effect of chronic exposure to low levels of SFN on the growth of breast cells has not been fully explored.. In the present study we assessed the effect of SFN on the growth of an immortalized breast cell line (MCF10A), and two breast cancer cell lines; the estrogen receptor positive MCF-7 cell line, and the estrogen receptor negative TMX2-28 cell line.

Plants use diverse mechanisms influenced by vast regulatory networks of indefinite scale to adapt to their environment. These regulatory networks have an unknown potential for epistasis between genes within and across networks. To test for epistasis within an adaptive trait genetic network, we generated and tested 47 Arabidopsis thaliana double mutant combinations for 20 transcription factors, which all influence the accumulation of aliphatic glucosinolates, the defense metabolites that control fitness. The epistatic combinations were used to test if there is more or less epistasis depending on gene membership within the same or different phenotypic subnetworks. Extensive epistasis was observed between the transcription factors, regardless of subnetwork membership. Metabolite accumulation displayed antagonistic epistasis, suggesting the presence of a buffering mechanism. Epistasis affecting enzymatic estimated activity was highly conditional on the tissue and environment and shifted between both ...

Broccoli (Brassica oleracea italica) - Nutri PeopleBroccoli (Brassica oleracea italica) - Nutri People
By Nutri People. First cultivated by the Romans, broccoli is related to the cabbage, cauliflower and Brussels sprout. Broccoli sprouts contain high amounts of active parts called sulphoraphanes. These act as indirect antioxidants, boosting what are called phase 2 detoxification enzymes, which trigger antioxidant activity throughout the body. Indirect antioxidants last longer in the body than direct antioxidants. Sulphoraphane levels drop as the broccoli plant grows older. Three-day old broccoli sprouts contain 20 to 50 times more sulphoraphanes than the mature cooked vegetable. Broccoli supplements should be free from goitrens.. ...

Degradation of glucosinolates1
  • Internal degradation of glucosinolates might also be involved in diurnal or developmental adaptations of the glucosinolate profile. (mpg.de)
Composition of glucosinolates2
  • The findings were supported by the composition of glucosinolates in the coronatine-insensitive mutant coi1 , the ctr1 mutant displaying constitutive triple response, and the SA-overproducing mpk4 and cpr1 mutants. (plantphysiol.org)
  • Content and composition of glucosinolates in leaves of 2 traditional and 8 low-glucosinolate (LG) varieties of oilseed rape (B. napus) grown in Poznan during 1994-95 was determined by HPLC at 3 different stages of development. (eurekamag.com)
Amino acids3
  • They are synthesized from certain amino acids: So-called aliphatic glucosinolates derived from mainly methionine, but also alanine, leucine, isoleucine, or valine. (wikipedia.org)
  • Glucosinolates are derived from amino acids and have a core structure consisting of a β-D-glucopyranose residue linked to a ( Z )- N -hydroximino sulfate ester via a sulfur atom and a variable side chain ( Halkier and Gershenzon, 2006 ). (frontiersin.org)
  • The first committed step in biosynthesis of the core structure of glucosinolates is the conversion of amino acids to the corresponding aldoximes. (plantphysiol.org)
Glucobrassicin1
  • They are the aliphatic glucosinolates progoitrin (PRO), gluconapin (NAP), glucobrassicanapin (GBN), the indolyl glucosinolates 4-hydroxyglucobrassicin (4OH), glucobrassicin (GBC), 4-methoxyglucobrassicin (4ME), neoglucobrassicin (NEO) and the aromatic glucosinolate gluconasturtiin (NAS). (wur.nl)
Progoitrin1
  • This is largely due to 5-vinyloxazolidine2-thione (Fig. 2), derived from 2-hydroxy-3-butenyl glucosinolate ("progoitrin"), which, as the name suggests, has goitrogenic activity. (springer.com)
Indolyl2
  • Purification and Analysis of Desulfo Indolyl Glucosinolates. (barnesandnoble.com)
  • These compounds, along with indolyl glucosinolate degradation products, have also been shown to have anticarcinogenic activity. (springer.com)
Crucifers1
  • 1-Isothiocyanato-3-(methylsulfinyl)-propane (IMSP) is a glucosinolate hydrolysis product formed from 3-methylsulfinylpropylglucosinolate when crucifers are eaten. (illinois.edu)
