Abstract:
1. A method for producing a dipeptide, comprising: allowing a protein having proline iminopeptidase activity to act on an L-amino acid ester and an L-amino acid to form the dipeptide, wherein said protein is selected from the group consisting of (A) and (B): (A) a protein comprising the amino acid sequence of SEQ ID NO: 5, (B) a protein comprising an amino acid sequence that includes substitution, deletion, insertion or addition of one to ten of amino acid(s) in the amino acid sequence of SEQ ID NO: 5, and has activity to produce a dipeptide from an L-amino acid ester and an L-amino acid, wherein said L-amino acid ester is one or more members selected from the group consisting of an L-alanine ester, a glycine ester, and L-valine ester, an L-isoleucine ester, an L-methionine ester, an L-phyenylalanine ester, an L-serine ester, an L-threonine ester, an L-glutamine ester, an L-tyrosine ester, an L-arginine ester, an L-aspartic acid-α-ester, an L-aspartic acid-β-ester, an L-leucine ester, an L-asparagine ester, an L-lysine ester, an L-aspartic-α,β-dimethyl ester and L-glutamine-γ-ester.
