Found in a variety of Aspergillus species (imperfect fungi): Aspergillus awamori (awamorin, aspergillopepsin A: ), A. foetidus (aspergillopepsin F: ), A. fumigatus , A. kawachii , A. niger (proteinase B, proctase B: [2,4]), A. oryzae (trypsinogen kinase: [3,10]), A. saitoi (aspergillopeptidase A: ), and A. sojae [5,10]. In peptidase family A1 (pepsin A family). Formerly included in EC 3.4.23.6

The enzyme appears in viruses and cellular organisms
Reaction Schemes
hydrolysis of proteins with broad specificity. Generally favours hydrophobic residues in P1 and P1', but also accepts Lys in P1, which leads to activation of trypsinogen. Does not clot milk

Synonyms
aspartic protease, aspartic proteinase, acid protease, carboxyl proteinase, carboxyl protease, aspergillopepsin i, aspergillopepsin, aspergillopepsin a, aspergillus protease, asp f 13, more
