Abstract:
:A cDNA containing the entire coding sequence for the subunit protein of rat liver class theta glutathione S-transferase (GST) Yrs-Yrs was isolated from a rat liver lambda gt11 cDNA library. The cDNA, designated GST theta-1, consisted of 1,258 bp which had an open reading frame of 732 bp encoding a polypeptide of 244 amino acid (AA) residues, including the leading AA Met to be removed on expression. The authenticity of the cDNA structure was supported by matching its deduced AA sequence with N-termini of Yrs and peptides obtained thereof by tryptic digestion as well as by CNBr cleavage. The deduced AA sequence of the subunit Yrs (M.W. 27,311) had only a weak homology (19-23%) with those of rat liver classes alpha, mu, and pi GST isozymes. Thus, the first evidence for the molecular cloning of the class theta GST was provided.
