Abstract:
1. A method for modifying a target protein or peptide with a molecular weight of 5,000 or more, comprising allowing an enzyme, which is capable of deamidating amido groups in target proteins and peptides by directly acting upon said amido groups, without cutting peptide bonds and without cross-linking said target proteins or peptides, to act on said target protein or peptide, wherein said enzyme is selected from the group consisting of (a) a polypeptide which comprises the amino acid sequence set forth in SEQ ID NO:6, (b) a polypeptide which comprises the amino acid sequence encoded by the nucleotide sequence set forth in SEQ ID NO:5, and (c) a polypeptide which comprises the amino acid sequence encoded by the nucleotide sequence which has a homology of 80% or more with the nucleotide sequence set forth in SEQ ID NO:5.
