Membrane glutathione S-transferases from the class of membrane-associated proteins in eicosanoid and glutathione metabolism (MAPEG) form a superfamily of detoxification enzymes that catalyze the conjugation of reduced glutathione (GSH) to a broad spectrum of xenobiotics and hydrophobic electrophiles. Evolutionarily unrelated to the cytosolic glutathione S-transferases, they are found across bac...
Mycolyl-transferases are a family of proteins that are specifically present in the CMN (Corynebacterium, Mycobacterium and Nocardia) genera and are responsible for the synthesis of cell wall components. We modeled the three-dimensional structures of mycolyl-transfersases from Corynebacterium and Nocardia using homology modeling methods based on the crystal structures of mycolyl-transferases fro...
A monoclonal antibody has been produced in the mouse system using purified rat liver ligandin as antigen. The antibody is of the immunoglobulin M class and appears to be specific for the Ya subunit of lowest molecular weight which comprises the isoenzymes of glutathione S-transferases in rat liver. Of the series of glutathione S-transferases, the antibody cross-reacted with purified ligandin (Y...
Chitin synthase is responsible for the biosynthesis of chitin, an essential component of the fungal cell wall. There is a long-standing question as to whether "processive" transferases such as chitin synthase operate in the same manner as non-processive transferases. The question arises from analysis of the polysaccharide structure--in chitin, for instance, each sugar residue is rotated approxi...
We have examined the effects of adding glutathione and isolated cytosolic glutathione S-transferases A, B, and C to rat liver microsomes metabolizing benzo(a)pyrene. Addition of glutathione alone resulted in the conjugation of 15 to 20% of the total metabolites of benzo(a)pyrene, and this conjugation could be inhibited almost entirely by bromosulfophthalein (an inhibitor of glutathione S-transf...
Acrylamide (AC) is a noxious chemical and it is widely used in this modernized world. There by this study aimedto assess the acrylamide induced neurotoxicity and genotoxicityonmale wistar rat brain. Based on the study aim, male at brainwas exposed by short term and long term to acrylamide and investigated the crucial changes in glutathione S-transferases and its associated glutathione peroxidas...
An investigation 111 vitro of pulmonary O-methyl transferases rcvcaled the presence of microsomal phenol-O-methyl transferase and soluble and microsomal catechol-O-methyl transferases in guineapig lung tissue. Both phenol and catechol transferases also were detected in rat and rabbit lung tissue. Substrates of guinea-pig pulmonary phenol-0-mcth!l transfcrasc ~ncludcJ phenols. crcsols and xyleno...
Lipid peroxidation in vitro in rat liver microsomes (microsomal fractions) initiated by ADP-Fe3+ and NADPH was inhibited by the rat liver soluble supernatant fraction. When this fraction was subjected to frontal-elution chromatography, most, if not all, of its inhibitory activity could be accounted for by the combined effects of two fractions, one containing Se-dependent glutathione (GSH) perox...
