title: Molecular weight and amino acid composition of the exocellular DD-carboxypeptidase-transpeptidase of Streptomyces R61.
abstract: A procedure allowing the purification of milligram amounts of the exocellular dd-carboxypeptidase-transpeptidase from Streptomyces R61 to protein homogeneity (95% purity) is described. The isolated protein has a molecular weight of about 38000 and consists of one polypeptide chain. Its amino acid composition is presented.
