Identification of sorcin by mass spectrometry analysis and database searching. (A) MS/MS spectrum of a doubly-charged peak at m/z 752.8. The corresponding peptide is identified as ITFDDYIACCVK (154–165). (B) MS/MS spectrum of a doubly-charged peak at m/z 490.8. The corresponding peptide is identified as LMVSMLDR (77–84), in which the methionine is oxidized. (C) Identification of sorcin by MS/MS analysis. The data were searched against SwissProt database through Mascot engine.
