ENTRY EC 3.4.23.24
NAME Candidapepsin
Candida albicans aspartic proteinase
CLASS Hydrolases
Acting on peptide bonds (peptidases)
Aspartic endopeptidases
REACTION Preferential cleavage at the carboxyl of hydrophobic amino acids,
but fails to cleave Leu15-Tyr, Tyr16-Leu and Phe24-Phe of insulin
B chain. Activates trypsinogen, and degrades keratin
SUBSTRATE Protein
Peptide
Trypsinogen
Keratin
H2O
PRODUCT Protein
Peptide
Trypsin
INHIBITOR Pepstatin
COMMENT 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. Formerly
included in EC 3.4.23.6.
