γ-Glutamyltransferase bound to prostatic subcellular organelles and in free form in human seminal plasma
Most of the γglutamyltransferase occurring in semen was found to be bound to the membranes of prostatic organelles, as is the case with Mg+plus;-Ca+plus;-dependent ATPase, and Zn+plus;-dependent peptidase hydrolysing succinyl (alanine)3-paranitroanilide. Organelie-bound γglutamyltransferase was released in a water-soluble form by papain. Charge shift electrophoresis revealed the presence in semina
