Characterization of rat spleen prostaglandin H D-isomerase as a sigma-class GSH transferase.
The prostaglandin H D-isomerase of rat immune accessory cells has been purified from spleen by a simple procedure, and its high specificity and activity [Urade, Fujimoto, Ujihara and Hayaishi (1987) J. Biol. Chem. 262, 3820-3825] have been confirmed in an assay coupled to prostaglandin H synthase. The enzyme also decreases the formation of 12[S]-hydroxy-5,8,10-heptadecatrienoic acid formed by t...
متن کاملSequence, catalytic properties and expression of chicken glutathione-dependent prostaglandin D2 synthase, a novel class Sigma glutathione S-transferase.
The Expressed Sequence Tag database has been screened for cDNA clones encoding prostaglandin D2 synthases (PGDSs) by using a BLAST search with the N-terminal amino acid sequence of rat GSH-dependent PGDS, a class Sigma glutathione S-transferase (GST). This resulted in the identification of a cDNA from chicken spleen containing an insert of approx. 950 bp that encodes a protein of 199 amino acid...
متن کاملPurification and characterization of a new cytosolic glutathione S-transferase (glutathione S-transferase X) from rat liver.
A hitherto unknown cytosolic glutathione S-transferase from rat liver was discovered and a method developed for its purification to apparent homogeneity. This enzyme had several properties that distinguished it from other glutathione S-transferases, and it was named glutathione S-transferase X. The purification procedure involved DEAE-cellulose chromatography, (NH4)2SO4 precipitation, affinity ...
متن کاملIsolation 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...
متن کاملPurification and physical characterization of glutathione S-transferase K
A novel hepatic enzyme, glutathione S-transferase K, is described that, unlike previously characterized transferases, possesses little affinity for S-hexylglutathione-Sepharose 6B but can be isolated because it binds to a glutathione affinity matrix. A purification scheme for this new enzyme was devised, with the use of DEAE-cellulose, S-hexylglutathione-Sepharose 6B, glutathione-Sepharose 6B a...
