| EC Number | 3.4.23.18 |
| Enzyme Function | FUNCTION: Secreted aspartic endopeptidase that allows assimilation of proteinaceous substrates. The scissile peptide bond is attacked by a nucleophilic water molecule activated by two aspartic residues in the active site. Shows a broad primary substrate specificity. Favors hydrophobic residues at the P1 and P1' positions, but also accepts a lysine residue in the P1 position, leading to the activation of trypsinogen and chymotrypsinogen A. {ECO:0000250|UniProtKB:Q12567}. |
