Acrosin
Definition:
EC Tree > 3 Hydrolases > 3.4 Acting on peptide bonds (peptidases) > 3.4.21 Serine endopeptidases > 3.4.21.10 acrosin
Acrosin is a sperm serine endopeptidase in family S1, formed from proacrosin by limited proteolysis and inhibited by naturally occurring trypsin inhibitors; it preferentially cleaves Arg and Lys bonds. By digesting the zona pellucida it enables sperm penetration during fertilisation.
