Glutathione transferases (GST) were purified from locally isolated bacteria, Acinetobacter calcoaceticus Y1, by glutathione-affinity chromatography and anion exchange, and their substrate specificities were investigated. SDS-polyacrylamide gel electrophoresis revealed that the purified GST resolved into a single band with a molecular weight (MW) of 23 kDa. 2-dimensional (2-D) gel electrophoresi...

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...

An imbalance between phase I drug metabolizing enzymes and phase II detoxification enzymes may contribute to the development of pre-eclampsia. Polymorphic variants in the phase I enzyme, cytochrome P450 genes may lead to increased toxification, whereas polymorphisms in the phase II enzyme, glutathione S-transferase genes may result in impaired detoxification. Most abundant in placenta and decid...

glutathione s-transferases (gsts) are encoded by a superfamily of genes and play a role in the detoxification of potential carcinogens. the human gsts are divided into four classes: alpha, mu, pi and theta. previous studies indicated that the absence of the glutathione s-transferase m1 (gstm1) protein correlated with an increased risk of developing some types of cancers. association between spe...

An immunohistochemical study of glutathione S-transferase (GST) expression in hepatocellular carcinoma and cholangiocarcinoma is described. Unlike most animal models of hepatic malignancy pi class GST was not consistently overexpressed in hepatocellular carcinoma. This tumour type either predominantly expressed alpha class GST or failed to express GST. By contrast, cholangiocarcinoma always exp...

An initial stage of fibrillogenesis in solutions of glutathione S-transferase-huntingtin (GST-HD) fusion proteins has been studied by using dynamic light scattering. Two GST-HD systems with poly-L-glutamine (polyGln) extensions of different lengths (20 and 51 residues) have been examined. For both systems, kinetics of z-average translation diffusion coefficients (Dapp) and their angular depende...

Glutathione S-transferases (GSTs) are a family of isoenzymes that play an important role in protecting cells from cytotoxic and carcinogenic agents. The pi-class GST has been associated with preneoplastic and neoplastic changes. Recently, it has been reported that regulatory sequences near the GSTP1 gene, which encodes the human pi-class GST, are commonly hypermethylated in prostatic carcinomas...

The chromate reductase purified from Pseudomonas ambigua was found to be homologous with several nitroreductases. Escherichia coli DH5alpha and Vibrio harveyi KCTC 2720 nitroreductases were chosen for the present study, and their chromate-reducing activities were determined. A fusion between glutathione S-transferase (GST) and E. coli DH5alpha NfsA (GST-EcNfsA), a fusion between GST and E. coli...

Cells expressing elevated levels of allelic variants of human glutathione S-transferase P1 (GSTP1) and/or efflux transporters, MRP1 or MRP2, were used to evaluate the role of GSTP1-1 in cisplatin resistance. These studies revealed that GSTP1-1 confers low-level resistance (1.4- to 1.7-fold) to cisplatin-induced cytotoxicity in MCF7 cells. However, expression of MRP1 (MCF7 cells) or MRP2 (HepG2 ...
