Abstract
Process for the production of a disaccharide-tripeptide and disaccharide-tetrapeptide which comprises applying an endo-N-acetylmuramidase from Streptomyces globisporus and a D-alanyl-meso-2,6-diaminopimelic acid endopeptidase from Streptomyces nitrosporeus SK (FERM BP-216) or Streptomyces globisporus to hydrolyze cell walls of bacteria such as Lactobacillus plantarum and Corynebacterium diphtheriae. Said process can give the desired disaccharide-tripeptide and disaccharide-tetrapeptide having excellent pharmacological activities such as immunostimulant activity and potentiating activity of nonspecific resistance to bacterial infections in the form of a single compound (i.e. not mixture thereof) in a high yield.
