Glutathione S-transferases (GSTs) are proteins synthesized in plants and responsible for their tolerance to environmental stresses. However, little information is available on the GST gene family of sweet potato, a globally important crop. The genetic evolution GSTs potato remains unclear. present study investigated by transcriptomic comparative genomic analyses. A total 51 were identified. Gen...
Dermal 7alpha- and 7beta-hydroperoxycholest-5-en-3beta-ols (cholesterol 7alpha- and 7beta-hydroperoxides), regarded as good aging markers in the rat (Ozawa, N., Yamazaki, S., Chiba, K., Aoyama, H., Tomisawa, H., Tateishi, M., and Watabe, T. (1991) Biochem. Biophys. Res. Commun. 178, 242-247), were reduced in the presence of glutathione (GSH) with concomitant formation of GSSG by cytosol from ra...
Glutathione transferases(GSTs) are a diverse family of enzymes found ubiquitously in aerobic organisms. They play a central role in the detoxification of both endogenous and xenobiotic compounds and are also involved in intracellular transport, biosynthesis of hormones and protection against oxidative stress. Interest in insect GSTs has primarily focused on their role in insecticide resistanc...
By BLAST searching a large expressed sequence tag database for glutathione S-transferase (GST) sequences we have identified 25 soybean (Glycine max) and 42 maize (Zea mays) clones and obtained accurate full-length GST sequences. These clones probably represent the majority of members of the GST multigene family in these species. Plant GSTs are divided according to sequence similarity into three...
PURPOSE The glutathione S-transferases (GSTs) constitute a family of cytosolic isoenzymes that are involved in the detoxication of electrophilic xenobiotics. The purpose of this investigation was to determine the concentration and cellular distribution of the various classes of cytosolic GSTs in the retina of control and triethyl lead-treated rats and thereby reveal mechanisms by which the cell...
Glutathione S-transferases (GSTs) are enzymes that detoxify electrophilic compounds. Earlier studies from our laboratory showed that anti-GST antibodies interfered with the fertilising ability of spermatozoa from Capra hircus (goat) in vitro, suggesting that GSTs are localised at the cell surface. In this study, we provide evidence for the presence of GSTs of 24 kDa on the sperm plasma membrane...
The biotransformation of foreign substances (xenobiotic) including drugs in the body is divided into phase I, II and III. But phase II enzymes are playing a key role in the biotransformation of endogenous compounds and xenobiotics to easily excretable forms and also the metabolic inactivation of pharmacologically active substances. The phase II enzymes can perform biotransformation through conj...
Microarray transcript profiling and RNA interference are two new technologies crucial for large-scale gene function studies in multicellular eukaryotes. Both rely on sequence-specific hybridization between complementary nucleic acid strands, inciting us to create a collection of gene-specific sequence tags (GSTs) representing at least 21,500 Arabidopsis genes and which are compatible with both ...
The underlying need for glutathione S-transferase (Gst) induction is thought to be an adaptive response to chemical stress within the cell. Classical microsomal enzyme inducers (MEIs) increase the expression of biotransformation enzymes (phase I and II) and transporters through transcription factors, such as the aryl hydrocarbon receptor (AhR), constitutive androstane receptor (CAR), pregnane X...
recent research highlights the importance of gsts in the establishment of chronic helminth infections. gsts have the potential to protect the parasite against the host immune response. in this present study, gst enzyme assay has been investigated on whole extract of f. hepatica and sheep liver tissue. to the 1-ml plastic cuvette, added 200 mm potassium phosphate buffer. then added 50 mm gsh red...
