Description
This protein also has EC 2.3.2.2 (γ-glutamyltransferase) activity. The enzyme consists of two chains that are created by the proteolytic cleavage of a single precursor polypeptide. The N-terminal L-threonine of the C-terminal subunit functions as the active site for both the cleavage and the hydrolysis reactions. The human enzyme also hydrolyses oxidized glutathione and leukotriene C4 with similar efficiency, while the mouse enzyme does not
