    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.

    摘要： The present invention describes a method for generating a serine derivative and an optically active isomer thereof by a convenient technique, and an enzyme and the like useful in the method. In the presence of the following protein (A) and/or (B) having an enzymatic activity, an α-amino acid is reacted with an aldehyde to form a serine derivative: (A) a protein comprising the amino acid sequence of SEQ ID NO:5, and (B) a protein comprising an amino acid sequence of SEQ ID NO: 5, but which includes substitution, deletion, insertion and addition of one or more amino acids and is able to catalyze the reaction to form the serine derivative.
