The proteolytic activity of human prostate-specific antigen

Biochem Biophys Res Commun. 1984 Sep 17;123(2):482-8. doi: 10.1016/0006-291x(84)90256-0.

Abstract

Human prostate-specific antigen has been found to exhibit a mild activity of protease at neutral pH. This finding is based on two observations: a proteolytic activity was always associated with the antigen fractions during purification, and the proteolytic activity and the antigen were precipitated with specific antibody to the antigen. In comparison with physico-chemical and catalytic properties of known proteases, human prostate-specific antigen is a distinct neutral protease.
