HUMAN PROCARBOXYPEPTIDASE A4.

Overview

Treatment of advanced stages of prostate carcinoma with, histone-deacetylase inhibitors entails expression of human, procarboxypeptidase-A4 (hPCPA4). The three-dimensional structure of hPCPA4, has been solved and shows the features of related metallocarboxypeptidase, zymogens, with a preformed alpha/beta/-hydrolase active-enzyme moiety, (hCPA4) and an inhibiting pro-domain (PD). The protease moiety recalls a, sphere, out of which a spherical cone has been cut. This results in a, funnel-like structure, at the bottom of which the active-site cleft, resides. The border of this funnel is shaped by loops, which are, responsible for the interaction with the PD, characterised by a large, interface area and relatively few contacts. Such an inhibitory mode is, evocative of the recently reported ... [(full description)]
