    摘要： The present invention is to provide an excellent peptide-synthesizing protein and a method for efficiently producing a peptide. A peptide is synthesized by reacting an amine component and a carboxy component in the presence of at least one of proteins shown in the following (I) and (II): (I) The mutant protein having the amino acid sequence containing one or more mutations of the above mutations 1 to 38 in the amino acid sequence described in SEQ ID NO:2; and (II) The mutant protein having the amino acid sequence containing one or more mutations selected from the group consisting of substitution, deletion, insertion, addition and inversion at positions other than one or more mutation positions of the above mutation 1 to 38 in the mutant protein described in the above (I), and having a peptide-synthesizing activity.
