FIELD: biotechnology, microbiology, peptides.
SUBSTANCE: invention relates to a method for preparing dipeptide from L-amino acid ester and L-amino acid using culture of microorganisms possessing ability for producing dipeptide from L-amino acid ester and L-amino acid. Method involves using cells of microorganisms of genus Pseudomonas or Corynebacterium isolated from culture or disrupted cells of these microorganisms, or lyophilized cells of such microorganisms. By other variant method involves using a protein possessing proline iminopeptidase activity instead microorganism culture. Invention provides preparing dipeptides with high effectiveness degree using inexpensive parent substance by industrially economy and simple way.
EFFECT: improved preparing method.
