Abstract
A new intracellular .beta.-glucosidase was isolated from T. reesei. It was sequentially purified by (NH4)2SO4 precipitation and chromatography and rechromatography on Sephadex G-150. The enzyme has a MW of 98,000, optimal activity at pH 6.5, an isoelectric point of 4.4 and Km values of 6.7 and 3.3 mM for sophorose and cellobiose, respectively. Possible functions of the enzyme may be regulation of cellulase induction and/or to serve as a proenzyme.This publication has 10 references indexed in Scilit:
