Structure of a tau class glutathione S-transferase from wheat active in herbicide detoxification.
Glutathione S-transferases (GSTs) from the phi (GSTF) and tau (GSTU) classes are unique to plants and play important roles in stress tolerance and secondary metabolism as well as catalyzing the detoxification of herbicides in crops and weeds. We have cloned and functionally characterized a group of GSTUs from wheat treated with fenchlorazole-ethyl, a herbicide safener. One of these enzymes, TaG...
متن کاملA phi class glutathione S-transferase from Oryza sativa (OsGSTF5): molecular cloning, expression and biochemical characteristics.
A glutathione S-transferase (GST) related to the phi (F) class of enzymes only found in plants has been cloned from the Oryza sativa. The GST cDNA was cloned by PCR using oligonucleotide primers based on the OsGSTF5 (GenBank Accession No. AF309382) sequences. The cDNA was composed of a 669-bp open reading frame encoding for 223 amino acids. The deduced peptide of this gene shared on overall ide...
متن کاملChemopreventive effect of S-allylcysteine and its relationship to the detoxification enzyme glutathione S-transferase.
Sulfur-containing substances derived from garlic and onion have been shown to prevent experimental carcinogenesis. One of the hypotheses explaining the mechanisms of the chemopreventive activity of these substances is that they activate detoxification systems such as glutathione S-transferase (GST). In this study the effects of S-allylcysteine (SAC), a water-soluble organosulfur compound derive...
متن کاملBinding of heme by glutathione S-transferase: a possible role of the erythrocyte enzyme.
Human erythrocyte glutathione S-transferase activity is inhibited, probably competitively, by hemin with a Ki of 10(-7) M. It is postulated that glutathione S-transferase functions physiologically as a hemin-binding and/or transport protein in developing erythroid cells.
متن کاملErythrocyte glutathione S-transferase. Electrophoretic identification of two enzyme forms.
Starch-gel electrophoresis was used to demonstrate two forms of glutathione S-transferase in human erythrocytes. Whereas considerable inter-individual differences in enzyme activity and electrophoretic patterns were detected, intra-individual differences were small.
