Abstract

The present invention provides a method for chemically removing a N-terminal methionine residue selectively, specifically and efficiently from a peptide or a salt thereof having an optionally oxidized methinine residue at its N-terminal. The method reacts a peptide or a salt thereof having an optionally oxidized methinine residue at its N-terminal with an .alpha.-diketone derivative, followed by hydrolysis.
