Data base searches were performed using Mascot and annotation of the MS/MS spectra was done manually. Amino-acid residues that differ from the published salmon sequence (C0H9B6) are bold. Amino-acid modifications: pyroQ, pyroglutamate, (delta mass: −17); ox, oxidized methionine (delta mass: +16); cam, carbamidomethyl, (delta mass: +57).
