Glucoamylase of Aspergillus niger.

Abstract

Aspergillus niger produces two extracellular glucoamylases (GAI of Mr 85 300 and GAII of Mr 77 600) separable on DEAE-cellulose. The enzymes differes in electrophoretic mobility, thermostability and substrate specificity. The GAI/GAII ratio depends on the concentration and form of nitrogen (nitrate or ammonium) in the culture medium. Proteinase VIII from Bacillus subtilis converts GAI to a form showing properties similar to those of GAII. Possible proteolytic degradation of GAI to GAII by Asp. niger endogenous proteinase(s) is suggested.
