Inhibition of aspartic proteinases by propart peptides of human procathepsin D and chicken pepsinogen

FEBS Lett. 1991 Aug 5;287(1-2):160-2. doi: 10.1016/0014-5793(91)80040-a.

Abstract

Two propart peptides of aspartic proteinases, the propart peptide of chicken pepsin and human cathepsin D, respectively, were investigated from the point of view of their inhibitory activity for a set of aspartic proteinases. These peptides display a very broad inhibitory spectrum. The strongest inhibition was observed for pepsin A-like proteinases where propart peptides can be used as titrants of active enzymes.
