An object of the present invention is to provide a method for producing an excellent peptide-producing protein and a peptide having good efficiency. That is, the peptide is produced by reacting the amine component with the carboxy component in the presence of at least one of the proteins shown in the following (I) and (II). (I) a mutant protein having an amino acid sequence comprising the mutation of any one or two or more of mutations 1 to 68, mutations 239 to 290, and 324 to 377 in the amino acid sequence set forth in SEQ ID NO: 2, and (II) sequence A mutant protein having an amino acid sequence comprising the mutation of any one or two or more of the mutations L1 to L335 and M1 to M642 in the amino acid sequence set forth in No. 208. |
