چکیده

Glutathione S-transferases (GSTs) are a superfamily of multifunctional enzymes, widely distributed in living organisms. Recently, more and more insect genome sequences are available. Genomic characterizations and comparative analyses of insect GSTs have been performed. In addition, application of high-throughput technologies, such as microarray and next-generation sequencing technology, have accelerated the identification of inducible and resistant GSTs. In this review, we mainly discussed the progress in comparative genomic analysis of insect GSTs and identification of inducible and resistant GSTs using the high-throughput technologies.

Genetic Variations in Human Glutathione Transferase Enzymes: Significance for Pharmacology and Toxicology

Glutathione transferase enzymes (GSTs) catalyze reactions in which electrophiles are conjugated to the tripeptide thiol glutathione. While many GST-catalyzed transformations result in the detoxication of xenobiotics, a few substrates, such as dihaloalkanes, undergo bioactivation to reactive intermediates. Many molecular epidemiological studies have tested associations between polymorphisms (esp...

Isolation and characterization of Phi class glutathione transferase partial gene from Iranian barley

Glutathione transferases are multifunctional proteins involved in several diverse intracellular events such as primary and secondary metabolisms, signaling and stress metabolism. These enzymes have been subdivided into eight classes in plants. The Phi class, being plant specific, is the most represented. In the present study, based on the sequences available at GenBank, different primers were d...

Xenobiotic response in Drosophila melanogaster: sex dependence of P450 and GST gene induction.

The effect of xenobiotics (phenobarbital and atrazine) on the expression of Drosophila melanogaster CYP genes encoding cytochromes P450, a gene family generally associated with detoxification, was analyzed by DNA microarray hybridization and verified by real-time RT-PCR in adults of both sexes. Only a small subset of the 86 CYP genes was significantly induced by the xenobiotics. Eleven CYP gene...

Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...

Effects of DIMBOA on detoxification enzymes of the aphid Rhopalosiphum padi (Homoptera: aphididae).

The presence of glutathione transferases and esterase activity was investigated in Rhopalosiphum padi and the effects of the cereal hydroxamic acid, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) on these detoxification enzymes was studied. Activity of glutathione S-transferases and general esterases was determined for adult aphids feeding on a natural diet lacking DIMBOA and on an artif...
