Proteinase, Aspergillus oryzae is a serine protease, optimally active at pH 10.5, that hydrolyzes peptide bonds and efficiently degrades substrates like casein. Its activity is inhibited by DFP and potato inhibitor, and it catalyzes proteolysis via serine residues. This enzyme is notable for its high yield and cost-effective production, finding applications in food processing, detergents, and the leather industry.
