  The present invention provides a method for producing a peptide, comprising culturing a transformant introduced with an expression vector to prepare a culture, and mixing the culture with a carboxy component and an amine component to form the peptide. The expression vector comprises a polynucleotide encoding a protein: (A) having selected deletions in the amino acid sequence of SEQ ID NO:2, (B) having a mutation of one or several amino acid residues in any protein selected from said group (A); (C) having 70% or more amino acid sequence identity to any protein selected from said group (A), (D) encoded by a polynucleotide that hybridizes under a stringent condition with a polynucleotide consisting of a nucleotide sequence complementary to a polynucleotide encoding any protein selected from said group (A), and (E) encoded by a polynucleotide having 70% or more nucleotide sequence identity to the polynucleotide encoding any protein selected from the group (A).
