Enzyme Information

3.4.23.24
Candidapepsin.
based on mapping to UniProt P0CY27
Preferential cleavage at the carboxyl of hydrophobic amino acids, but fails to cleave 15-Leu-|-Tyr-16, 16-Tyr-|-Leu-17 and 24-Phe-|-Phe-25 of insulin B chain. Activates trypsinogen, and degrades keratin.
-!- This endopeptidase from the imperfect yeast Candida albicans is inhibited by pepstatin, but not by methyl 2-diazoacetamido-hexanoate or 1,2-epoxy-3-(p-nitrophenoxy)propane. -!- Belongs to peptidase family A1. -!- Formerly EC 3.4.4.17 and EC 3.4.23.6.
