STUDIES ON SEVERAL DYNAMIC PROPERTIESOF THE ACID PROTEASE OBTAINED FROMASPERGILLS NIGER HD-404

Gao Lujiao Wang Huizhong Weng Xinghua(Dept.of Biolo,East China Normal University)(Dept.of Biolo)(College of life science HangZhou University)  
The effects of metal ions. EDTA,surface active reagent -and indoacetic acid on the activity of the acid protease obtained from Aspergillus niger HD-404 were studied. The results showed that Cu2+ and Mn2+ could stimulate the activity of the enzyme stongly. When Cu2+ ,Mn2+ and Al3+ were added at the same time.they produced coordinate effect. thus the enzyme was activated highly. And the results also showed that this enzyme was inhibited dramatically by sodiurnlauryl sulfonate (SDS) or West Lake effective detergent, and that while Casein was used as sbtrate. AgNO3 was an irreversible inhibitor of the enzyme.
