title: Synthesis of aza and oxaglutamyl-p-nitroanilide derivatives and their kinetic studies with gamma-glutamyltranspeptidase.
abstract: A new series of L-glutamic acid p-nitroanilide analogues has been synthesized and tested as substrates and inhibitors of rat kidney gamma-glutamyltranspeptidase (GGT). Kinetic parameters (K(m) and k(cat)) were determined for each analogue and provide insight into the scope and limits of GGT catalytic efficiency.
