Studies on the Proteolytic Enzymes of Black Aspergilli

Part VI. Further Studies on the Specificity of Crystalline Aspergitlus Saitoi Protease

Abstract

In order to determine the specificity of Aspergillus Saitoi protease, the hydrolyzate of Bchainof insulin oxidized by this enzyme was investigated on paperchromatography accordingto the 2, 4-dinitrofluorobenzene technique. Specificity was compared with pepsin and other proteolytic enzymes.
