It was shown that preparations of bovine kidney gamma-glutamyl transferase with different degree of purity are phosphorylated by cAMP-dependent protein kinase. Phosphorylation is accompanied by a simultaneous decrease of both transferase and hydrolase activities of the enzyme. Hence, gamma-glutamyltransferase may serve as a substrate and target of regulation by cAMP-dependent protein kinase.
