Abstract
SUMMARY: Levansucrase in the corynebacterium studied is apparently an adaptive enzyme. Its optimal formation is dependent on the presence of an inducer (sucrose) and an organic nitrogen source. High nitrogen concentrations increase growth rate and sucrose hydrolysis and significantly decrease levansucrase formation. The pH activity curve of the levansucrase studied is asymmetric and the optimal pH value for its activity is 7·0. These findings suggest that this levansucrase differs from other levansucrases so far described.
