Oryzin (EC 3.4.21.63, Aspergillus alkaline proteinase, aspergillopeptidase B, API 21, aspergillopepsin B, aspergillopepsin F, Aspergillus candidus alkaline proteinase, Aspergillus flavus alkaline proteinase, Aspergillus melleus semi-alkaline proteinase, Aspergillus oryzae alkaline proteinase, Aspergillus parasiticus alkaline proteinase, Aspergillus serine proteinase, Aspergillus sydowi alkaline proteinase, Aspergillus soya alkaline proteinase, Aspergillus melleus alkaline proteinase, Aspergillus sulphureus alkaline proteinase, prozyme, P 5380, kyorinase, seaprose S, semi-alkaline protease, sumizyme MP, prozyme 10, onoprose, onoprose SA, protease P, promelase) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

Hydrolysis of proteins with broad specificity, and of Bz-Arg-OEt > Ac-Tyr-OEt. Does not hydrolyse peptide amides

This enzyme is a predominant extracellular alkaline endopeptidase of the mold Aspergillus oryzae.
