Studies on the Proteolytic Enzymes of Black Aspergilli

Part V. The Specificity of Crystalline Asp. Saitoi Proteinase by Application of the Sanger DNP-Method

Abstract

1. The oxidized egg-white lysozyme was hydrolyzed with crystalline Asp. Saitoi pro-teinase and the resulting N-terminal residues were detected by the DNP-technique of Sanger.
2. It was proved that Asp. Saitoi proteinase has a considerably wider range of specificity than pepsin and Bac. subtilis proteinase.
