Abstract:
1. An isolated enzyme having peptide-forming activity, said enzyme consisting of a sequence selected from the group consisting of (A), (B), (M), and (N): (A) an amino acid sequence consisting of amino acid residue numbers 23 to 616 of SEQ ID NO:6, (B) an amino acid sequence including substitution, deletion, insertion, and/or addition, of one to 30 amino acids in amino acid residue numbers 23 to 616 of SEQ ID NO:6, and has at least 50% of the peptide-forming activity of a protein corresponding to unmutated amino acid residue numbers 23 to 616 of SEQ ID NO:6 at 50° C. and apH of 8, (M) an amino acid sequence consisting of SEQ ID NO:6, and (N) an amino acid sequence including substitution, deletion, insertion, and/or addition, of one to 30 amino acids in an amino acid sequence consisting of SEQ ID NO:6, and has at least 50% of the peptide-forming activity of a protein corresponding to unmutated SEQ ID NO:6 at 50° C. and a pH of 8.
