A novel class of protein from wheat which inhibits xylanases. (1/3819)We have purified a novel class of protein that can inhibit the activity of endo-beta-1,4-xylanases. The inhibitor from wheat (Triticum aestivum, var. Soisson) is a glycosylated, monomeric, basic protein with a pI of 8.7-8.9, a molecular mass of 29 kDa and a unique N-terminal sequence of AGGKTGQVTVFWGRN. We have shown that the protein can inhibit the activity of two family-11 endo-beta-1, 4-xylanases, a recombinant enzyme from Aspergillus niger and an enzyme from Trichoderma viride. The inhibitory activity is heat and protease sensitive. The kinetics of the inhibition have been characterized with the A. niger enzyme using soluble wheat arabinoxylan as a substrate. The Km for soluble arabinoxylan in the absence of inhibitor is 20+/-2 mg/ml with a kcat of 103+/-6 s-1. The kinetics of the inhibition of this reaction are competitive, with a Ki value of 0.35 microM, showing that the inhibitor binds at or close to the active site of free xylanase. This report describes the first isolation of a xylanase inhibitor from any organism. (+info)
Purification of gibberellic acid-induced lysosomes from wheat aleurone cells. (2/3819)Using isopycnic density gradient centrifugation, lysosomes were concentrated in a single region of a sucrose-Ficoll gradient (p = 1-10 g cm-3), well separated from most other cell organelles. Gibberellic acid-induced lysosomes were found to be rich in alpha-amylase and protease but not ribonuclease. The lysosomal band also contained a majority of the NADH2-cytochrome c reductase, a marker enzyme for endoplasmic reticulum, found in the gradient. Examination of electron micrographs revealed that a purified band of lyosomes contained at least 3 vesicle types, ranging in size from 0-1 to 0-5 mum. The significance of these findings to proposed mechanisms of action of gibberellic acid is discussed. (+info)
Evolutionary dynamics of Ty1-copia group retrotransposons in grass shown by reverse transcriptase domain analysis. (3/3819)The evolutionary dynamics of Ty1-copia group retrotransposons in grass were examined by reverse transcriptase (RT) domain analysis. Twenty-three rice RT sequences were newly determined for this report. Phylogenetic analysis of 177 RT sequences, mostly derived from wheat, rice, and, maize, showed four distinct families, which were designated G1, G2, G3, and G4. Three of these families have elements obtained from distantly related species, indicative of origins prior to the radiation of grass species. Results of Southern hybridization and detailed comparisons between the wheat and rice sequences indicated that each of the families had undergone a distinct pattern of evolution. Multiple families appear to have evolved in parallel in a host species. Analyses of synonymous and nonsynonymous substitutions suggested that there is a low percentage of elements carrying functional RT domains in the G4 family, indicating that the production of new G4 elements has been controlled by a small number of elements carrying functional RT domains.

The influence of a diet rich in wheat fibre on the human faecal flora. (4/3819)The effect on the faecal flora of adding wheat fibre to a controlled diet in four healthy volunteers for a 3-week period has been observed. No change in the concentration of the bacteria in the bacterial groups counted was found, although there was a slight increase in total output associated with increased faecal weight. The predominant organisms in all subjects were non-sporing anaerobes, but the dominant species in each subject was different and was unaffected by changing the diet. Similarly, the concentration of faecal beta-glucuronidase detected in two subjects was unaltered and the concentration of clostridia able to dehydrogenate the steroid nucleus found in one subject was unaltered. It is suggested that the faecal microflora is not primarily controlled by the presence of undigested food residues in the large bowel. (+info)
Physical and functional heterogeneity in TYMV RNA: evidence for the existence of an independent messenger coding for coat protein. (5/3819)Turnip yellow mosaic virus RNA can be separated into two distinct components of 2 times 10(6) and 300 000 daltons molecular weight after moderate heat treatment in the presence of SDS or EDTA. The two species cannot have arisen by accidental in vitro degradation of a larger RNA, as they both possess capped 5' ends. Analysis of the newly synthesized proteins resulting from translation of each RNA by a wheat germ extract shows that the 300 000 molecular weight RNA can be translated very efficiently into coat protein. When translated in vitro the longer RNA gave a series of high molecular weight polypeptides but only very small amounts of a polypeptide having about the same mass as the coat protein. Thus our results suggest that the small RNA is the functional messenger for coat protein synthesis in infected cells. (+info)
Genetic selection of mutations in the high affinity K+ transporter HKT1 that define functions of a loop site for reduced Na+ permeability and increased Na+ tolerance. (6/3819)Potassium is an important macronutrient required for plant growth, whereas sodium (Na+) can be toxic at high concentrations. The wheat K+ uptake transporter HKT1 has been shown to function in yeast and oocytes as a high affinity K+-Na+ cotransporter, and as a low affinity Na+ transporter at high external Na+. A previous study showed that point mutations in HKT1, which confer enhancement of Na+ tolerance to yeast, can be isolated by genetic selection. Here we report on the isolation of mutations in new domains of HKT1 showing further large increases in Na+ tolerance. By selection in a Na+ ATPase deletion mutant of yeast that shows a high Na+ sensitivity, new HKT1 mutants at positions Gln-270 and Asn-365 were isolated. Several independent mutations were isolated at the Asn-365 site. N365S dramatically increased Na+ tolerance in yeast compared with all other HKT1 mutants. Cation uptake experiments in yeast and biophysical characterization in Xenopus oocytes showed that the mechanisms underlying the Na+ tolerance conferred by the N365S mutant were: reduced inhibition of high affinity Rb+ (K+) uptake at high Na+ concentrations, reduced low affinity Na+ uptake, and reduced Na+ to K+ content ratios in yeast. In addition, the N365S mutant could be clearly distinguished from less Na+-tolerant HKT1 mutants by a markedly decreased relative permeability for Na+ at high Na+ concentrations. The new mutations contribute to the identification of new functional domains and an amino acid in a loop domain that is involved in cation specificity of a plant high affinity K+ transporter and will be valuable for molecular analyses of Na+ transport mechanisms and stress in plants.

Cloning and expression of a wheat (Triticum aestivum L.) phosphatidylserine synthase cDNA. Overexpression in plants alters the composition of phospholipids. (7/3819)We describe the cloning of a wheat cDNA (TaPSS1) that encodes a phosphatidylserine synthase (PSS) and provides the first strong evidence for the existence of this enzyme in a higher eukaryotic cell. The cDNA was isolated on its ability to confer increased resistance to aluminum toxicity when expressed in yeast. The sequence of the predicted protein encoded by TaPSS1 shows homology to PSS from both yeast and bacteria but is distinct from the animal PSS enzymes that catalyze base-exchange reactions. In wheat, Southern blot analysis identified the presence of a small family of genes that cross-hybridized to TaPSS1, and Northern blots showed that aluminum induced TaPSS1 expression in root apices. Expression of TaPSS1 complemented the yeast cho1 mutant that lacks PSS activity and altered the phospholipid composition of wild type yeast, with the most marked effect being increased abundance of phosphatidylserine (PS). Arabidopsis thaliana leaves overexpressing TaPSS1 showed a marked enhancement in PSS activity, which was associated with increased biosynthesis of PS at the expense of both phosphatidylinositol and phosphatidylglycerol. Unlike mammalian cells where PS accumulation is tightly regulated even when the capacity for PS biosynthesis is increased, plant cells accumulated large amounts of PS when TaPSS1 was overexpressed. High levels of TaPSS1 expression in Arabidopsis and tobacco (Nicotiana tabacum) led to the appearance of necrotic lesions on leaves, which may have resulted from the excessive accumulation of PS. The cloning of TaPSS1 now provides evidence that the yeast pathway for PS synthesis exists in some plant tissues and provides a tool for understanding the pathways of phospholipid biosynthesis and their regulation in plants.

Plant cell-directed control of virion sense gene expression in wheat dwarf virus. (8/3819)We have used particle bombardment (biolistics) to deliver replication-competent wheat dwarf virus (WDV)-based constructs, carrying reporter gene sequences fused to the virion sense promoter (Pv) or the CaMV 35S promoter, to suspension culture cells and immature zygotic embryos of wheat. While the replication of WDV double-stranded DNA forms (replicons) was equivalent between wheat suspension culture cells and embryos, GUS reporter gene activity was 20-40 times higher in the embryo cultures. Maximum expression of WDV replicons occurred in the embryonic axis tissue of wheat embryos but their expression in suspension cells was compromised, compared with transiently maintained input plasmid DNA containing the same sequences. From these studies, we propose that WDV replicons are subject to a host cell-controlled competency for virion sense transcription. The term competency is used to distinguish between the phenomenon described here and control of gene expression by specific transcription factors. Control of competency is independent of Pv, the replacement 35S promoter and of the complementary sense control of virion sense expression involving specific sequences in Pv. We propose that factors controlling the competency for replicon expression may be present in cells which, as well as maintaining high rates of DNA synthesis, are totipotent. Cell type control of active chromatin, methylation of specific sequences in WDV minichromosomes and/or interaction of virus-encoded proteins with specific host factors are considered as possible mechanisms.

RNA, Transfer, Tyr refers to a specific type of transfer RNA (tRNA) molecule that carries the amino acid tyrosine (Tyr) during protein synthesis. Transfer RNAs are small RNA molecules that play a crucial role in the process of translation, which is the process by which the genetic information encoded in messenger RNA (mRNA) is used to synthesize proteins. Each tRNA molecule has a specific sequence of nucleotides that allows it to recognize and bind to a specific codon on the mRNA molecule. The codon is a sequence of three nucleotides that corresponds to a specific amino acid. In the case of RNA, Transfer, Tyr, it binds to the codon UAC, which codes for the amino acid tyrosine. During translation, the tRNA molecule carrying the tyrosine amino acid binds to the mRNA molecule at the corresponding codon, and the ribosome then catalyzes the formation of a peptide bond between the tyrosine and the growing polypeptide chain. This process continues until the ribosome reaches a stop codon on the mRNA molecule, at which point the newly synthesized protein is released. Overall, RNA, Transfer, Tyr is an essential component of the process of protein synthesis, and its proper functioning is critical for the production of functional proteins in cells.

Ribulose-1,5-bisphosphate carboxylase (RuBisCO) is an enzyme that plays a central role in the process of photosynthesis in plants, algae, and some bacteria. It catalyzes the reaction between carbon dioxide and ribulose-1,5-bisphosphate (RuBP), a 5-carbon sugar, to form two molecules of 3-phosphoglycerate (3-PGA), a 3-carbon compound. This reaction is the first step in the Calvin cycle, which is the primary pathway for carbon fixation in photosynthesis. RuBisCO is the most abundant enzyme on Earth and is responsible for fixing approximately 60% of the carbon dioxide in the atmosphere. However, it is also a slow enzyme and is often limited by the availability of carbon dioxide in the environment. This can lead to a phenomenon known as photorespiration, in which RuBisCO instead catalyzes the reaction between RuBP and oxygen, leading to the loss of carbon dioxide and the production of a variety of byproducts. In the medical field, RuBisCO has been studied as a potential target for the development of new drugs to treat a variety of conditions, including cancer, diabetes, and obesity. Some researchers have also explored the use of RuBisCO as a biosensor for detecting carbon dioxide levels in the environment or as a tool for producing biofuels.

In the lungs, cadmium exposure can cause inflammation, scarring, and an increased risk of lung cancer. Long-term exposure to cadmium has also been associated with an increased risk of prostate cancer in men. In the medical field, cadmium is often measured in blood, urine, and hair samples to assess exposure levels and potential health risks. Treatment for cadmium poisoning typically involves supportive care to manage symptoms and prevent further exposure. In some cases, chelation therapy may be used to remove cadmium from the body.
DNA primers are short, single-stranded DNA molecules that are used in a variety of molecular biology techniques, including polymerase chain reaction (PCR) and DNA sequencing. They are designed to bind to specific regions of a DNA molecule, and are used to initiate the synthesis of new DNA strands. In PCR, DNA primers are used to amplify specific regions of DNA by providing a starting point for the polymerase enzyme to begin synthesizing new DNA strands. The primers are complementary to the target DNA sequence, and are added to the reaction mixture along with the DNA template, nucleotides, and polymerase enzyme. The polymerase enzyme uses the primers as a template to synthesize new DNA strands, which are then extended by the addition of more nucleotides. This process is repeated multiple times, resulting in the amplification of the target DNA sequence. DNA primers are also used in DNA sequencing to identify the order of nucleotides in a DNA molecule. In this application, the primers are designed to bind to specific regions of the DNA molecule, and are used to initiate the synthesis of short DNA fragments. The fragments are then sequenced using a variety of techniques, such as Sanger sequencing or next-generation sequencing. Overall, DNA primers are an important tool in molecular biology, and are used in a wide range of applications to study and manipulate DNA.
Glucosyltransferases are a group of enzymes that transfer glucose molecules from a donor substrate to an acceptor substrate. These enzymes play important roles in various biological processes, including the synthesis of complex carbohydrates, glycosylation of proteins and lipids, and the metabolism of drugs and toxins. In the medical field, glucosyltransferases are often studied in the context of diseases such as cancer, diabetes, and inflammatory disorders. For example, certain types of cancer cells overexpress specific glucosyltransferases, which can contribute to the growth and spread of the tumor. Similarly, changes in the activity of glucosyltransferases have been implicated in the development of diabetes and other metabolic disorders. In addition, glucosyltransferases are also important targets for drug development. For example, inhibitors of specific glucosyltransferases have been shown to have anti-cancer and anti-inflammatory effects, and are being investigated as potential therapeutic agents.
In the medical field, carbon dioxide (CO2) is a gas that is produced as a byproduct of cellular respiration and is exhaled by the body. It is also used in medical applications such as carbon dioxide insufflation during colonoscopy and laparoscopic surgery, and as a component of medical gases used in anesthesia and respiratory therapy. High levels of CO2 in the blood (hypercapnia) can be a sign of respiratory or metabolic disorders, while low levels (hypocapnia) can be caused by respiratory failure or metabolic alkalosis.
Plant extracts refer to the active compounds or bioactive molecules that are extracted from plants and used in the medical field for various therapeutic purposes. These extracts are obtained through various extraction methods, such as solvent extraction, steam distillation, and cold pressing, and can be used in the form of powders, liquids, or capsules. Plant extracts have been used for centuries in traditional medicine and are now widely used in modern medicine as well. They are used to treat a wide range of conditions, including inflammation, pain, anxiety, depression, and cancer. Some examples of plant extracts used in medicine include aspirin (extracted from willow bark), quinine (extracted from cinchona bark), and morphine (extracted from opium poppy). Plant extracts are also used in the development of new drugs and therapies. Researchers extract compounds from plants and test them for their potential therapeutic effects. If a compound shows promise, it can be further developed into a drug that can be used to treat a specific condition. It is important to note that while plant extracts can be effective in treating certain conditions, they can also have side effects and may interact with other medications. Therefore, it is important to consult with a healthcare professional before using plant extracts as a form of treatment.
In the medical field, RNA, Messenger (mRNA) refers to a type of RNA molecule that carries genetic information from DNA in the nucleus of a cell to the ribosomes, where proteins are synthesized. During the process of transcription, the DNA sequence of a gene is copied into a complementary RNA sequence called messenger RNA (mRNA). This mRNA molecule then leaves the nucleus and travels to the cytoplasm of the cell, where it binds to ribosomes and serves as a template for the synthesis of a specific protein. The sequence of nucleotides in the mRNA molecule determines the sequence of amino acids in the protein that is synthesized. Therefore, changes in the sequence of nucleotides in the mRNA molecule can result in changes in the amino acid sequence of the protein, which can affect the function of the protein and potentially lead to disease. mRNA molecules are often used in medical research and therapy as a way to introduce new genetic information into cells. For example, mRNA vaccines work by introducing a small piece of mRNA that encodes for a specific protein, which triggers an immune response in the body.
Nitrates are a group of compounds that contain the nitrate ion (NO3-). In the medical field, nitrates are commonly used to treat angina (chest pain caused by reduced blood flow to the heart muscle) and high blood pressure (hypertension). They work by relaxing the smooth muscles in blood vessels, which allows blood to flow more easily and reduces the workload on the heart. Nitrates are available in various forms, including tablets, ointments, and sprays. They are usually taken as needed to relieve symptoms, but may also be taken on a regular schedule to prevent angina attacks or lower blood pressure. It is important to note that nitrates can have side effects, such as headache, flushing, and low blood pressure, and should be used under the guidance of a healthcare provider.
Amino acids are organic compounds that are the building blocks of proteins. They are composed of an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R group) that varies in size and structure. There are 20 different amino acids that are commonly found in proteins, each with a unique side chain that gives it distinct chemical and physical properties. In the medical field, amino acids are important for a variety of functions, including the synthesis of proteins, enzymes, and hormones. They are also involved in energy metabolism and the maintenance of healthy tissues. Deficiencies in certain amino acids can lead to a range of health problems, including muscle wasting, anemia, and neurological disorders. In some cases, amino acids may be prescribed as supplements to help treat these conditions or to support overall health and wellness.
Transcription factors are proteins that regulate gene expression by binding to specific DNA sequences and controlling the transcription of genetic information from DNA to RNA. They play a crucial role in the development and function of cells and tissues in the body. In the medical field, transcription factors are often studied as potential targets for the treatment of diseases such as cancer, where their activity is often dysregulated. For example, some transcription factors are overexpressed in certain types of cancer cells, and inhibiting their activity may help to slow or stop the growth of these cells. Transcription factors are also important in the development of stem cells, which have the ability to differentiate into a wide variety of cell types. By understanding how transcription factors regulate gene expression in stem cells, researchers may be able to develop new therapies for diseases such as diabetes and heart disease. Overall, transcription factors are a critical component of gene regulation and have important implications for the development and treatment of many diseases.
