Class-Pi of Glutathione S-Transferases
Class-Pi of glutathione s-transferases (GST-Pi) is the specific form of GSTs that are known to participate particularly in the mechanisms of resistance to drugs and carcinogens. This class of the enzyme is referred to as class-P or class-Pi or class π. The accepted terminology in this review article is class-Pi. In this article following a brief description of identified molecular forms of GSTs...
متن کاملGlutathione S-transferases Null Genotype in Acute Myeloid Leukaemia
Background: The glutathione S-transferase (GST) family of metabolising enzymes plays an important role in the detoxification of mutagens and carcinogens. The expression of many of these cancer susceptibility enzymes is genetically polymorphic. An increased frequency of GST-null genotypes has been associated with several malignancies. Objective: To investigate the rate of GSTT1 and GSTM1 null ge...
متن کاملGlutathione S Transferases: Biochemistry, Polymorphism and Role in Colorectal Carcinogenesis
Glutathione S-transferases (GSTs) are enzymes detoxifying a wide range of hazardous substances both of endogenous or exogenous origin, such as reactive oxygen species (ROS) or xenobiotics and environmental carcinogens; thereby imparting protection to DNA against oxidative damage. GST gene polymorphisms on the other hand, exert an effect on the functioning of enzymes encoded by these genes at bo...
متن کاملGlutathione S - transferases of the bovine retina
We have purified two isoenzymes of glutathione S-transferase from bovine retina to apparent homogeneity through a combination of gel-filtration chromatography, affinity chromatography and isoelectric focusing. The more anionic (pI = 6.34) and less anionic (pI = 6.87) isoenzymes were comparable with respect to kinetic and structural parameters. The Km for both substrates, reduced glutathione and...
متن کاملRat lung glutathione S - transferases
Two immunologically distinct types of 22000-Mr subunits are present in rat lung glutathione S-transferases. One of these subunits is probably similar to Ya subunits of rat liver glutathione S-transferases, whereas the other subunit Ya' is immunologically distinct. Glutathione S-transferase II (pI7.2) of rat lung is a heterodimer (YaYa') of these subunits, and glutathione S-transferase VI (pI4.8...
