various concentrations as a selective inhibitor and have found that ATP at a concentration of lOmM abolishes arylsulphatase B activity but only inhibits 50% of the arylsulphatase A activity. By measuring the total activity and the activity in the presence of 1OmM-ATP we have been able to determine the activity of both forms in defined mixtures of the two. Thus the proportions of the two enzymes...

To explore the contribution of agricultural practices on enzymatic activity in Anopheles gambiae populations, collections gambiaelarve were done cotton vegetable farming (famers use for both,insecticides pest control) and subsistence (no insecticide) from district Banikoara, located Benin. Enzymatic activities such as total protein, monooxygenase P450, Glutathione-S-Transferase esterasewere inv...

Dexamethasone 21-methanesulfonate, an affinity label for glucocorticoid-binding proteins, was incubated with rat liver cytosol preparations. The predominant covalently labeled component was identified as Yb-glutathione-S-transferase on the basis of chromatographic properties, electrophoretic mobility, and specific retention by an anti-Yb-immunoadsorbent. Affinity labeling of this protein was bl...

Introduction: Gaseous air pollutants can cause oxidative stress, which can lead to lung damage by inducing inflammation. Polymorphisms in the glutathione S-transferase (GST) gene are involved in the pathogenesis of many diseases, including lung disease. Two glutathione S-transferase Mu 1 (GSTM1) and glutathione S-transferase theta 1 (GSTT1) genes belong to this family, in which deletions occur ...
