Identification of cations in the active centers of the carboxypeptidase ofStreptomyces griseus and the aminopeptidase ofAspergillus oryzae
- 21 Downloads
It has been shown by atomic adsorption spectroscopy that the active center of the molecule of the carboxypeptidase ofStreptomyces griseus contains 1 zinc atom and that of the aminopeptidase ofAspergillus oryzae 1 cobalt atom. The latter was also confirmed by the ESR method. In addition to the cobalt, 0.3 g-atom of strongly bound zinc, upon the pressure of which the enzymatic activity does not depend, has been found in the aminopeptidase.
