Class
Hydrolases;
Acting on peptide bonds (peptidases);
Aspartic endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Specificity similar to that of pepsin A. Cleaves Z-Lys!Ala-Ala-Ala and activates trypsinogen
Comment
From the imperfect yeast Rhodotorula glutinis. Somewhat similar enzymes have been isolated from the imperfect yeast-like organism Cladosporium sp. [4,6] and the imperfect fungus Paecilomyces varioti [1,2].
