^aThe calculated molecular mass was used to determine the theoretical peak position of the single (m/z) or double [m/(2z)] charged ion of the unmodified or demethionated (dMet) form of the protein.

^bAmino acid substitutions that lead to a mass change are underlined. Ellipses within brackets indicate parts of the sequence without differences; asterisks indicate stop codons.
