Molecular weight, amino acid composition and physicochemical properties of the exocellular dd-carboxypeptidase–transpeptidase of Streptomyces R39

摘要: The exocellular dd-carboxypeptidase–transpeptidase from Streptomyces R39 was purified to protein homogeneity and in milligram amounts. isolated enzyme consisted of one polypeptide chain molecular weight about 53300. Its amino acid composition several physicochemical properties were determined compared with those the exo-cellular R61.
