Secreted aspartic proteinase (SAP2) from Candida albicans complexed with A70450


Function and Biology Details

Reaction catalysed:
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.
