Zusammenfassung

Nach der entwickelten Theorie5 bestimmt man viskosimetrisch die HemmkonstanteK I=2,78·10−2 mMol/ml der hydrolytischen Reaktion der Natriumcarboxymethylcellulose (Na-CMC) unter der katalytischen Wirkung vonC x-Cellulasenenzym [(EC 3.2.1.4), (β-1,4-Glucan-4-glucanohydrolase)], aus Aspergillus oryzae isoliert, und unter der Hemmwirkung des kompetitiven Hemmstoffs Lactose.

Abstract

According to a recently developed theory5, an inhibition constantK I=2,78·10−2 mMol/ml was determined viscosimetrically for the hydrolase reaction of sodium carboxymethyl cellulose (Na-CMC) withC x-cellulase enzyme (EC 3.2.1.4, β-1,4-glucan-4-glucanohydrolase), isolated from Aspergillus oryzae. Lactose was used as a competitive inhibitor.
