Three hundred arid fifty three lactating sows were used to determine the effects of increased dietary lysine on sow and litter performance. At farrowing, sows were assigned to com-soybean meal lactation diets consisting of either 1.0 or 1.3% total lysine. A treatment by parity interaction was observed, with first parity sows fed 1.3% lysine having heavier litter weaning weights than sows fed 1.00/0 lysine. Surprisingly, third and fourth parity sows fed 1.3% lysine had lower litter weaning weights than those fed 1.0% lysine. No other treatment by parity interactions existed. No differences were observed in the number of pigs weaned or pig survivability. Sows fed 1.3 % lysine tended to consume less feed in the first week of lactation than sow fed 1.0% lysine (9.6 vs 10.0 Ibid), with no differences observed during week 2 or overall. No differences were observed in subsequent performance of the sows on days to estrus; farrowing rate; or number of pigs born, born alive, stillborn, or born mummified. ...
TY - JOUR. T1 - Effects of dietary lysine supplementation in cats with enzootic upper respiratory disease. AU - Maggs, David J. AU - Sykes, Jane E. AU - Clarke, Heather E.. AU - Yoo, Seung H.. AU - Kass, Philip H. AU - Lappin, Michael R.. AU - Rogers, Quinton. AU - Waldron, Mark K.. AU - Fascetti, Andrea J. PY - 2007/4. Y1 - 2007/4. N2 - To determine the effectiveness of dietary lysine supplementation in cats with enzootic upper respiratory disease (URD), 50 cats were fed a ration containing 11 or 51 g lysine/kg diet for 52 days. Food intake, body weight, clinical signs, plasma amino acid concentrations and presence of Chlamydophila felis or feline herpesvirus (FHV)-1 DNA within the conjunctival fornix were assessed. Food and lysine intake of both dietary groups decreased between days 17 and 22, coinciding with peak disease and viral presence. Mean disease score for cats fed the supplemented ration (0.94) was higher than for those fed the basal diet (0.21); however, this could be attributed to a ...
A 14-day growth trial was conducted to determine the threonine: lysine ratio necessary to optimize growth performance of the segregated early-weaned (SEW) pig. Twelve experimental diets included two levels of lysine (1.15% and 1.5% apparent digestible lysine) and six apparent digestible threonine: lysine ratios (40, 45, 50, 55, 60, and 65 %) in a 2 x 6 factorial arrangement. Growth performance was improved by feeding 1.5% rather than 1.15% digestible lysine. Growth performance decreased linearly as the digestible threonine: lysine ratio increased. Although a significant quadratic response was not observed, this reduction in growth performance did not appear to occur until the threonine ratio exceeded 45% of lysine on an apparent digestible basis. These data indicate that the threonine requirement for the SEW pig is approximately 45% of digestible lysine ...
Enoyl-coenzyme A hydratase/3-hydroxyacyl-coenzyme A (EHHADH) is an important enzyme which catalyze two steps in fatty acid oxidation. There are four acetylated lysine residues been identified in EHHADH, which are Lys165, Lys171, Lys346 and Lys584. Immunoprecipitation of ectopically expressed FLAG-tagged EHHADH and Western blotting with antibody to acetyllysine confirmed that EHHADH was indeed acetylated(Zhao, et al). In order to explore the effect of acetylation on fatty acid oxidation. Isobaric tags are used, which is TSA and NAM. TSA and NAM treatment increased all the four lysine residues acetylation. Consistently, corresponding unacetylated peptide was decreased. Scientists treat TSA and NAM to Chang Human Liver cells doubled the activity of EHHADH, which indicates that acetylation of EHHADH would increase fatty acid oxidation pathway. In order to confirm the result, site-directed mutagenesis was used and the four lysine residue was replaced by glutamine, TSA and NAM can no longer ...
Histidine - Arthritis Fighter. Lysine - Herpes Killer. L-lysine is an essential amino acid. Experimental animals on a lysine-deficient diet showed depressed growth and altered immune system function for several generations.. Normal requirements for lysine have been found to be about 8 g per day or 12 mg/kg in adults. Children and infants need more- 44 mg/kg per day for an eleven to-twelve-year old, and 97 mg/kg per day for three-to six-month old. Lysine is highly concentrated in muscle compared to most other amino acids.. Lysine is high in foods such as wheat germ, cottage cheese and chicken. Of meat products, wild game and pork have the highest concentration of lysine. Fruits and vegetables contain little lysine, except avocados.. Normal lysine metabolism is dependent upon many nutrients including niacin, vitamin B6, riboflavin, vitamin C, glutamic acid and iron. Excess arginine antagonizes lysine.. Several inborn errors of lysine metabolism are known. Most are marked by mental retardation with ...

Lysine is an amino acid, found widely in animal foods like meat, fish, and eggs, but now wildly popular as a supplement. Lysine has multiple benefits for both acne and health. Firstly, lysine is vital for collagen production, and therefore anti-ageing and strong skin. Both lysine and a structurally related compound it forms called allysine are raw materials for all collagen in your skin.. Secondly, lysine is an excellent remedy for stress, being known to reduce stress hormones strongly. Lysine activates the same receptors as benzos, the classic pharmaceutical anti-anxiety drugs, and it does so naturally. Lysine can even control serotonin receptors linked to anxiety.. Who is most at risk of deficiency? Easily vegans, vegetarians, and people who restrict animal foods for health. Unless youre smart and tactically eat the correct nuts and seeds using a meticulous system, lysine can be hard to obtain from plants alone.. That said, anyone can be lysine deficient. Is your skin weak, your face dull and ...
Lysine propionylation and butyrylation are protein modifications that were recently identified in histones. The molecular components involved in the two protein modification pathways are unknown, hindering further functional studies. Here we report identification of the first three in vivo non-histone protein substrates of lysine propionylation in eukaryotic cells: p53, p300, and CREB-binding protein. We used mass spectrometry to map lysine propionylation sites within these three proteins. We also identified the first two in vivo eukaryotic lysine propionyltransferases, p300 and CREB-binding protein, and the first eukaryotic depropionylase, Sirt1. p300 was able to perform autopropionylation on lysine residues in cells. Our results suggest that lysine propionylation, like lysine acetylation, is a dynamic and regulatory post-translational modification. Based on these observations, it appears that some enzymes are common to the lysine propionylation and lysine acetylation regulatory pathways. Our ...
Post-translational modifications (PTMs) play an important role in modulating diverse cellular processes, which are dynamic and reversible modifications of proteins during or after protein biosynthesis [1]. PTMs can change protein functions by introducing new functional groups such as acetyl, phospho, ubiquityl, succinyl and methyl groups. Among these changes, acetylation of lysine has been extensively studied in both eukaryotes and prokaryotes [2, 3]. Similar to lysine acetylation, lysine succinylation is one of the newly discovered PTMs that has been found in both eukaryotes and prokaryotes [1]. As one important PTM of proteins, lysine succinylation was defined as the transfer of a succinyl group to a lysine residue of a protein molecule [4].. Lysine succinylation was firstly discovered in histone proteins, and its role has been investigated in the regulation of gene transcription [5]. In addition to histones, other proteins in the nucleus, cytoplasm and mitochondria were also found to be ...

were fed the unlabelled diet for 20 d and then the labelled diet for 10 d while wearing a neck collar to avoid caecotrophy (group COLL), in order to discriminate it from direct intestinal absorption. At day 30 animals were slaughtered and caecal bacteria and liver samples taken. The 15N enrichment in amino acids of caecal bacteria and liver were determined by GC-combustion/isotope ratio MS. Lysine showed a higher enrichment in caecal microflora (0·925 atom% excess, APE) than liver (0·215 APE) in group ISOT animals, confirming the double origin of body lysine: microbial and dietary. The COLL group showed a much lower enrichment in tissue lysine (0·007 (SE 0·0029) APE for liver). Any enrichment in the latter animals was due to direct absorption of microbial lysine along the digestive tract, since recycling of microbial protein (caecotrophy) was avoided. In such conditions liver enrichment was low, indicating a small direct intestinal absorption. From the ratio of [15N]lysine enrichment between ...
MAXY-G34 is a pegylated variant of human granulocyte-colony stimulating factor (G-CSF). This variant contains multiple non-naturally occurring lysines that have been introduced into alpha helixes of wild type human G-CSF as PEGylation sites, and from which multiple undesired, naturally occurring lysines have been removed as compared to wild type human G-CSF to avoid PEGylation of such sites. Specifically, the amino acid sequence of MAXY-G34 differs from that of human wild type G-CSF at residues 16, 34, 40, 105 and 159. This was accomplished by removing the three lysine residues at positions 16, 34 and 40, and replacing them with arginine, and substituting two new lysine residues at positions 105 and 159. MAXY-G34 is pegylated with 5 kd mPEG SPA (succinimidyl propionate) groups at 3 amino acid residues, including PEG groups attached at the amino terminal end of the protein and at two internal lysine residues, while Neulasta has a single 20 Kd PEG group attached at the N terminal end of the wild type G

In clinical study, when Lysine hydrochloride (the form it is metabolized best from) is taken in concentrations of less than 1250mg (2 x 625mg tablets) it has a limited effect on the Herpes and cold sore virus - and when taken at a daily dose higher than 3000mg it is shown to be potentially unsafe.. It is important to find the happy medium, which is why the L-Lysine in Combined Lysine Formula is at a specific dose of 625mg of naturally occurring Lysine hydrochloride per tablet (equiv. 500mg of elemental Lysine). This concentration is like this for a reason.. Two 625 mg tablets is equal to the daily recommended dose of Lysine that is shown to retard Herpes in clinical trials. This is the amount you should be taking daily to help prevent outbreaks - its important not to take too much more than this if you are taking it everyday or for a long period of time.. We recommend increasing the dose only when you have active symptoms, like itching, tingling and pain. There is really no benefit in taking ...
To compare expense, we evaluate the metabolizable lysine cost in cents over grams (¢/g). The metabolizable lysine cost of AjiPro®-L is generally 1.6 ¢/g, whereas the price and quality of blood meal vary over time, resulting in a metabolizable lysine cost range of 1.5-3.0 ¢/g. From this perspective, AjiPro®-L generally delivers lysine in a more affordable way compared to blood meal.. Another advantage of AjiPro®-L is its ability to provide consistent, stable quality in the long term. Contrary to the variability in the quality of blood meal, AjiPro®-L delivers a consistent quality and amount of metabolizable lysine. This ensures a predictable, stable income over feed for dairy farmers.. ...

Both plasma and red blood cells contain amino acids (AA), but the relative amount of AA transferred from each vascular compartment to the tissues remains unclear. For splanchnic tissues, the relative transfers between the plasma, the red blood cells and the tissues may vary with nutritional state, but whether the same situation pertains for other tissues is not known. The current study focused on the transfer of lysine from plasma and red blood cells across the hindquarters of sheep offered four levels of intakes (0.5, 1.0, 1.5 and 2.5×maintenance energy). This design, coupled with use of [U-13C]lysine as tracer, also allowed the effect of intake on protein kinetics to be examined. At all intakes, the concentration of lysine in the sheep red blood cells exceeded that in plasma by 50 % (P,0.001), while the distribution of labelled lysine between the plasma and the red blood cells was 0.71:0.29. Net lysine uptake by the hindquarters increased in a linear manner (P,0.001) with intake, with more ...

The two paths of lysine synthesis seem to be quite unusual in the consistency of their dichotomous distribution over a broad range of biological forms. This consistency suggests that these paths did not arise sporadically, and that their distribution pattern was not disturbed by genetic exchange. It appears probable that neither path emerged in an organism possessing the other, since a partial appearance of either path in the presence of the other may well have been selected against, and an appearance in toto is thought unlikely in view of the number of enzymes involved in each path. It is thus assumed that the two lysine paths arose individually in organisms incapable of lysine synthesis ...

Protein therapeutics suffer from low oral bioavailability, mainly due to poor membrane permeability and digestion by gastrointestinal proteases. To improve proteolytic stability, intramolecular thioether crosslinks were introduced into a three-helix affibody molecule binding the human epidermal growth factor receptor (EGFR). Solid-phase peptide synthesis was used to produce an unmodified control protein domain and three different crosslinked protein domain variants: one with a thioether crosslink between the N-terminal lysine residue and a cysteine residue in the second loop region (denoted K4), a second with a crosslink between the C-terminal lysine residue and a cysteine residue in the first loop region (denoted K58), and a third with crosslinks in both positions (denoted K4K58). Circular dichroism (CD) and surface-plasmon-resonance-based (SPR-based) biosensor studies of the protein domains showed that the three-helix structure and high-affinity binding to EGFR were preserved in the ...

Epigenetic regulators of gene expression and chromatin state include so-called writers, erasers, and readers of chromatin modifications.Well-characterized examples of reader domains include bromodomains typically binding acetyllysine and chromatin organization modifier (chromo), malignant brain tumor (MBT), plant homeodomain (PHD), and Tudor domains generally associating with methyllysine. Research on epigenetic readers has been tremendously influenced by the discovery of selective inhibitors targeting the bromodomain and extraterminal motif (BET) family of acetyl-lysine readers. The human genome encodes 46 proteins containing 61 bromodomains clustered into eight families. Distinct experimental approaches are used to identify the first BET inhibitors, GSK 525762A and (+)-JQ-1..

In the feed industry :. Lysine is a kind of amino acid, which cant be compounded automatically in the animal body. It is indispensable for lysine to compound brain nerve, generative cell core protein and hemoglobin. Growing animals are prone to lack lysine. The faster animals grow, the more lysine animals need. So it is called the growing amino acid So it has the function of increasing the practical utilities of feed, improving the meat quality and promoting the growth of animals. In the food industry :. Lysine is one of the important compositions of protein. The body requires Lysine which is one of eight essential amino acids but cannot synthesize it so it must be provided in the diet. For a good enhancing agent, add lysine to potables, rice, flour, and it will rise up the rate for utilizing protein so that it can enhance food nutrition greatly. It is also an efficient dietary supplement in improving growth, adjusting appetite, reducing diseases, and making the body stronger. It can ...

The PHD finger of bromodomains serves as an epigenetic reader by recognizing the N-terminal histone H3 tail when it is methylated [14]. The function of BAZ1A-PHD, N-terminal to its bromodomain, is however unknown [12]. This can be attributed to the fact that BAZ1A-PHD lacks the "aromatic cage" as well as other key residues crucial for the recognition of trimethylated lysine [15]. BAZ1A-PHD also lacks acidic residues which particularly recognize unmethylated histone H3 lysine 4 (H3K4) peptides [16]. These information show proof that the PHD finger of BAZ1A might interact with DNA through its other biochemical properties other than the canonical residues which are absent [12]. The PHD of BAZ1A is structurally similar to its paralog, BAZ1B-PHD and the dual-zinc binding motif characteristic of their PHD fold have been found to be structurally conserved. BAZ1A-PHD is 54% identical and 73% similar to BAZ1B-PHD [12]. However, BAZ1A-PHD has been found to contain a positively charged feature possibly due ...

Borrelia burgdorferi, the causative agent of Lyme disease, expresses on its surface two decorin binding adhesins, DbpA and DbpB. Previous studies have demonstrated that vaccination of mice with DbpA provided protection against challenge with heterologous Borrelia strains despite considerable sequence variability among DbpA in these strains. We have now examined the importance of individual amino acid residues in DbpA for decorin binding. We demonstrated that chemical modification of lysine residues resulted in loss of ligand binding activity. Of the 27 lysine residues in native DbpA from strain 297, 6 are present in most and 5 are conserved in all 30 DbpA sequences examined so far. Analysis of recombinant DbpA in which individual lysine residues have been mutated to alanine suggested that three of the conserved residues distributed throughout the DbpA sequence are required for decorin binding. These mutants lost their ability to bind decorin in Western ligand blot assay and bound reduced amounts of
Efforts to increase lysine in maize. Efforts to increase maize lysine using traditional breeding have been pursued for many years. In 1964 the opaque2 mutants were found to produce elevated levels of lysine, essentially by decreasing zein storage proteins, allowing lysine-rich proteins to accumulate in the endosperm. The original mutants were unsuitable for commercial production, but introducing a battery of modifier genes improved the field and storage qualities of the maize. Breeding for quantitative trait loci have also resulted in the production of high-lysine maize in countries where it can impact human nutrition [6].. The mutant high lysine strains selected by conventional breeding have therefore succeeded in producing proteins richer in lysine than the existing maize lines.. Nevertheless Monsanto Corporation has created a GM maize line that employs a synthetic approximation of a bacterial gene to increase the level of lysine in the amino acid pools in the grain, and Monsanto has lodged a ...
Lysine methyltransferase which catalyze methylation of histone and nonhistone proteins, play a crucial role in diverse biological processes and has emerged as a promising target for the development of various human diseases, including cancer, inflammation, and psychiatric disorders. However, inhibiting Lysine methyltransferases selectively has presented many challenges to medicinal chemists. During the past decade, lysine methyltransferase inhibitors covering many different structural classes have been designed and developed. In this review, we describe the development of selective, small-molecule inhibitors of lysine methyltransferases with an emphasis on their discovery and chemical synthesis. We highlight the current state of lysine methyltransferase inhibitors and discuss future directions and opportunities for lysine methyltransferase inhibitor discovery.
Proteins lysine deacetylases (KDACs), like the vintage Zn2+-reliant histone deacetylases (HDACs) as well as the nicotinamide adenine dinucleotide (NAD+)-requiring sirtuins, are enzymes that play critical functions in various biological processes, specially the epigenetic rules of global gene manifestation applications in response to internal and exterior cues. manipulation of endogenous signaling pathways.

The present investigation was carried out to analyze the variation in lysine content in thirty six durum wheat genotypes under irrigation conditions. The cereal proteins are low in lysine one of the essential amino acids that cannot be synthesized by humans and must therefore be obtained entirely from dietary sources. Thus, lysine content constitutes an important feature for defining the nutritive value of flour obtained from cereals. Lysine content was found maximum in WHD 954 (3.53 g/16g N) followed by UAS 448 (3.52 g/16g N) and minimum was observed in MACS 3944 (2.05 g/16g N). These genotypes were found promising and may be used in crossing programme in order to improve grain quality.

Lysine-ketoglutarate reductase catalyzes the first step of lysine catabolism in maize (Zea mays L.) endosperm. The enzyme condenses L-lysine and alpha-ketoglutarate into saccharopine using NADPH as cofactor. It is endosperm-specific and has a temporal pattern of activity, increasing with the onset of kernel development, reaching a peak 20 to 25 days after pollination, and thereafter decreasing as the kernel approaches maturity. The enzyme was extracted from the developing maize endosperm and partially purified by ammonium-sulfate precipitation, anion-exchange chromatography on DEAE-cellulose, and affinity chromatography on Blue-Sepharose CL-6B. The preparation obtained from affinity chromatography was enriched 275-fold and had a specific activity of 411 nanomoles per minute per milligram protein. The native and denaturated enzyme is a 140 kilodalton protein as determined by polyacrylamide gel electrophoresis. The enzyme showed specificity for its substrates and was not inhibited by either ...
Posttranslational modification of proteins by acetylation and phosphorylation regulates most cellular processes in living organisms. Surprisingly, the evolutionary conservation of phosphorylated serine and threonine residues is only marginally higher than that of unmodified serines and threonines. With high-resolution mass spectrometry, we identified 1981 lysine acetylation sites in the proteome of Drosophila melanogaster. We used data sets of experimentally identified acetylation and phosphorylation sites in Drosophila and humans to analyze the evolutionary conservation of these modification sites between flies and humans. Site-level conservation analysis revealed that acetylation sites are highly conserved, significantly more so than phosphorylation sites. Furthermore, comparison of lysine conservation in Drosophila and humans with that in nematodes and zebrafish revealed that acetylated lysines were significantly more conserved than were nonacetylated lysines. Bioinformatics analysis using ...
The objective of this meta-analysis was to evaluate the response of growing-finishing pigs to different dietary methionine sources and to determine the ideal methionine:lysine ratio for nursery to finishing pigs. Data were obtained from peer-reviewed journals. Information were extracted from the material and methods and results sections of pre-selected articles. Forty one articles were included in the first database. Graphical and correlation analyses, multivariate exploratory analysis of factors, variance-covariance analysis, and non-linear models were applied to estimate nutritional requirements. Eighty-three percent of the articles in the database were not used for the determination of the methionine:lysine ratio because the diets did not meet the pigs lysine requirements. Methionine sources were compared using 21 articles of the first database, and performance differences were not found (P,0.05) among pigs fed diets containing L-methionine, DL-methionine, or methionine hydroxy analog. The ...

SET domain lysine methyltransferases (KMTs) methylate specific lysine residues in histone and non-histone substrates. These enzymes also display product specificity by catalyzing distinct degrees of methylation of the lysine epsilon-amino group. To elucidate the molecular mechanism underlying this specificity, we have characterized the Y245A and Y305F mutants of the human KMT SET7/9 (also known as KMT7) that alter its product specificity from a monomethyltransferase to a di- and a trimethyltransferase, respectively. Crystal structures of these mutants in complex with peptides bearing unmodified, mono-, di-, and trimethylated lysines illustrate the roles of active site water molecules in aligning the lysine epsilon-amino group for methyl transfer with S-adenosylmethionine. Displacement or dissociation of these solvent molecules enlarges the diameter of the active site, accommodating the increasing size of the methylated epsilon-amino group during successive methyl transfer reactions. Together, ...
Protein methylation is a common posttranslational modification that mostly occurs on arginine and lysine residues. Arginine methylation has been reported to regulate RNA processing, gene transcription, DNA damage repair, protein translocation, and signal transduction. Lysine methylation is best known to regulate histone function and is involved in epigenetic regulation of gene transcription. To better study protein methylation, we have developed highly specific antibodies against monomethyl arginine, asymmetric dimethyl arginine, and monomethyl, dimethyl, and trimethyl lysine motifs respectively. These antibodies were used to perform immunoaffinity purification (IAP) of methyl peptides followed by LC-MS/MS analysis to identify and quantify arginine and lysine methylation sites in several model studies. Overall, we identified over 1000 arginine methylation sites in human cell lines and mouse tissues, and approximately 160 lysine methylation sites in human cell line HCT116. The methylation sites ...
An extensive heterogeneous kinetic study was carried out for acid catalysed propionylation of cotton cellulose. In this study a series of metal chlorides and sulphuric acid as catalysts were used, and the effect of temperature, solvent medium, propionylation solution composition, and catalyst concentration on propionylation were investigated. The degree of propionylation was determined by a saponification method and, where necessary, confirmed by infrared spectroscopy and microanalysis. The reaction process was described on the basis of an initial, first, and second stage. Up to 15% of the completed reaction appeared to take place in the initial stage which is suggested to be diffusion controlled. Whereas the first and second stages were shown to be nondiffusion ones since they obeyed pseudo first-order kinetics with respect to the reacting hydroxyl groups. A mechanism and transition state complex were proposed for the propionylation reaction. Acid catalysed propionylation conditions (catalyst, ...
Post-translational lysine methylation is well established as a regulator of histone activity; however, it is emerging that these modifications are also likely to play extensive roles outside of the histone code.
Cellular metabolites, such as acyl-CoA, can modify proteins, leading to protein posttranslational modifications (PTMs). One such PTM is lysine succinylation, which is regulated by sirtuin 5 (SIRT5). Although numerous proteins are modified by lysine succinylation, the physiological significance of lysine succinylation and SIRT5 remains elusive. Here, by profiling acyl-CoA molecules in various mouse tissues, we have discovered that different tissues have different acyl-CoA profiles and that succinyl-CoA is the most abundant acyl-CoA molecule in the heart. This interesting observation has prompted us to examine protein lysine succinylation in different mouse tissues in the presence and absence of SIRT5. Protein lysine succinylation predominantly accumulates in the heart whenSirt5is deleted. Using proteomic studies, we have identified many cardiac proteins regulated by SIRT5. Our data suggest that ECHA, a protein involved in fatty acid oxidation, is a major enzyme that is regulated by SIRT5 and ...
© 2014 The Authors. Gene transcription responds to stress and metabolic signals to optimize growth and survival. Histone H3 (H3) lysine 4 trimethylation (K4me3) facilitates state changes, but how levels are coordinated with the environment is unclear. Here, we show that isomerization of H3 at the alanine 15-proline 16 (A15-P16) peptide bond is influenced by lysine 14 (K14) and controls gene-specific K4me3 by balancing the actions of Jhd2, the K4me3 demethylase, and Spp1, a subunit of the Set1 K4 methyltransferase complex. Acetylation at K14 favors the A15-P16. trans conformation and reduces K4me3. Environmental stress-induced genes are most sensitive to the changes atK14 influencing H3 tail conformation and K4me3. By contrast, ribosomal protein genes maintain K4me3, required for their repression during stress, independently of Spp1, K14, and P16. Thus, the plasticity in control of K4me3, via signaling to K14 and isomerization at P16, informs distinct gene regulatory mechanisms and processes involving
INTRODUCTION. Cereal grains contribute to over 60% of the total world food production. In spite of being among the most important species cultivated in the world and serving as a source of dietary calories and protein, maize grains are poor in both oil content (OQuinn et al., 2000; Romanelli & Milan, 2005) and quality protein (Varisi et al., 2007), since their predominant grain storage proteins, the zeins, are deficient in lysine and tryptophan (Azevedo et al., 1997; Ferreira et al., 2006; Landry & Delhaye, 2007) The study of nitrogen (N) metabolism has been a major factor to help understanding amino acids metabolism (Medici et al., 2004, 2005; Lea & Azevedo, 2006, 2007; Samborski et al., 2008). Different strategies have been used to improve these traits by either independent or concomitant approaches. Maize has been improved for high oil content alone (Adams & Jensen, 1987; Thomison et al., 2003), or both high oil and high lysine contents (OQuinn et al., 2000), using traditional plant ...

Speckle-type POZ protein (SPOP) is an E3 ubiquitin ligase adaptor protein that functions as a potential tumor suppressor, and SPOP mutations have been identified in ~10% of human prostate cancers. However, it remains unclear if mutant SPOP proteins can be utilized as biomarkers for early detection, diagnosis, prognosis or targeted therapy of prostate cancer. Moreover, the SPOP mutation sites are distributed in a relatively short region with multiple lysine residues, posing significant challenges for bottom-up proteomics analysis of the SPOP mutations. To address this issue, PRISM (high-pressure, high-resolution separations coupled with intelligent selection and multiplexing)-SRM (selected reaction monitoring) mass spectrometry assays have been developed for quantifying wild-type SPOP protein and 11 prostate cancer-derived SPOP mutations. Despite inherent limitations due to amino acid sequence constraints, all the PRISM-SRM assays developed using Arg-C digestion showed a linear dynamic range of at least

Glucosepane is a structurally complex protein posttranslational modification that is believed to exist in all living organisms. Research in humans suggests that glucosepane plays a critical role in the pathophysiology of both diabetes and human aging, yet comprehensive biological investigations of this metabolite have been hindered by a scarcity of chemically homogeneous material available for study. Here we report the total synthesis of glucosepane, enabled by the development of a one-pot method for preparation of the nonaromatic 4H-imidazole tautomer in the core. Our synthesis is concise (eight steps starting from commercial materials), convergent, high-yielding (12% overall), and enantioselective. We expect that these results will prove useful in the art and practice of heterocyclic chemistry and beneficial for the study of glucosepane and its role in human health and disease. ...
Interpretive Summary: Technical Abstract: The objective of this study was to determine the effect of feeding different lysine and metabolizable energy (ME) levels to developing gilts on age at puberty and reproductive tract measurements. Crossbred Large White × Landrace gilts (n = 1221) housed in groups from 100 d of age until slaughter (approximately 260 d of age) were randomly allotted to 6 corn-soybean diets formulated to provided 2 standardized ileal digestible lysine levels [100% (HL), 85% (LL)] and 3 ME levels [90% (LME), 100% (MME), 110% (HME)] at 100 d of age. The 100% lysine and 100% ME were based on an informal survey from the U.S. commercial swine industry to obtain average levels that are currently fed to developing gilts. Gilts were weighed and backfat thickness and loin muscle area were recorded at the beginning of the trial and then every 28 d. Starting at 160 d of age, gilts were exposed daily to vasectomized boars and observed for behavioral estrus. At slaughtered, their ...

The AUA codon-specific isoleucine tRNA (tRNA(Ile)) in eubacteria has the posttranscriptionally modified nucleoside lysidine (L) at the wobble position of the anticodon (position 34). This modification is a lysine-containing cytidine derivative that converts both the codon specificity of tRNA(Ile) from AUG to AUA and its amino acid specificity from methionine to isoleucine. We identified an essential gene (tilS; tRNA(Ile)-lysidine synthetase) that is responsible for lysidine formation in both Bacillus subtilis and Escherichia coli. The recombinant enzyme complexed specifically with tRNA(Ile) and synthesized L by utilizing ATP and lysine as substrates. The lysidine synthesis of this enzyme was shown to directly convert the amino acid specificity of tRNA(Ile) from methionine to isoleucine in vitro. Partial inactivation of tilS in vivo resulted in an AUA codon-dependent translational defect, which supports the notion that TilS is an RNA-modifying enzyme that plays a critical role in the accurate ...

This biotinylated peptide serves as a negative control and contains a scrambled version of the consensus motif sequence (SP-300). It will not be conjugated to SUMO-1, SUMO-2 or SUMO-3 proteins in the presence of the E1 activating (SAE1/SAE2) and UbcH9 conjugating enzymes. The biotin group allows for sensitive and convenient detection using avidin-linked reagents.. SUMO modification of proteins occurs on lysine residues generally found within a short consensus sequence containing the ψΚXE motif. This motif consists of ψ which represents a large hydrophobic amino acid (isoleucine, leucine or valine), K is the lysine that becomes modified, X is any residue and E is glutamic acid. The glutamic acid is the most highly conserved position other than the lysine.. ...

Epigenetic integrity is critical for many eukaryotic cellular processes. An important question is how different epigenetic regulators control development and influence disease. Lysine acetyltransferase 8 (KAT8) is critical for acetylation of histone H4 at lysine 16 (H4K16), an evolutionarily conserved epigenetic mark. It is unclear what roles KAT8 plays in cerebral development and human disease. Here, we report that cerebrum-specific knockout mice displayed cerebral hypoplasia in the neocortex and hippocampus, along with improper neural stem and progenitor cell (NSPC) development. Mutant cerebrocortical neuroepithelia exhibited faulty proliferation, aberrant neurogenesis, massive apoptosis, and scant H4K16 propionylation. Mutant NSPCs formed poor neurospheres, and pharmacological KAT8 inhibition abolished neurosphere formation. Moreover, we describe KAT8 variants in 9 patients with intellectual disability, seizures, autism, dysmorphisms, and other anomalies. The variants altered chromobarrel and ...
