Abstract
The number of extracellular and intracellular Cx enzyme components and their interrelations were studied using enzymes from strains, N–l (H 373) and C–3 (N 87), of P. oryzae. When P. oryzae was grown on carboxymethyl cellulose (CMC) as the carbon source, high activities were detected in Cx enzyme and β-glucosidase, with essentially no C1 enzyme activity. Purification of extracellular and intracellular Cx enzymes showed that the former consisted of three components (Ex–I, Ex–II and Ex–III) and the latter of two components (In–I and In–II). When the culture filtrate was incubated for 11 days at 28°C under sterile condition, the amount of component Ex–III, which was undetectable within the cell, increased with the concomitant decrease of that of component Ex–II. Thus, component Ex–II was suggested as converting to component Ex–III.This publication has 0 references indexed in Scilit:
