Evidence for the role of a trypsin-like enzyme in the hamster sperm acrosome reaction.

S Meizel, C W Lui.   

Abstract

Acrosome reactions occurring in vitro in hamster sperm capacitated by bovine follicular fluid were severly inhibited by four synthetic trypsin inhibitors and by Zn2+. Three polypeptide trypsin inhibitors and a synthetic chymotrypsin inhibitor did not inhibit the acrosome reaction, and Ca2+ overcame the inhibition by Zn2+. These results suggest that a trypsin-like enzyme (possibly acrosin) plays a role in the acrosome reaction.
