Localization of members of the gamma-glutamyl transpeptidase family identifies sites of glutathione and glutathione S-conjugate hydrolysis.

Plant physiology - 1 Aug 2007

Abstract excerpt

gamma-Glutamyl transpeptidases (GGTs) are essential for hydrolysis of the tripeptide glutathione (gamma-glutamate-cysteine-glycine) and glutathione S-conjugates since they are the only enzymes known to cleave the amide bond linking the gamma-carboxylate of glutamate to cysteine. In Arabidopsis thaliana, four GGT genes have been identified based on homology with animal GGTs. They are designated GGT1 (At4g39640),...
