Sequencing of tryptic peptides by ESI-QqTOF MS/MS for protein identification via sequence-similarity searching. (A) MS spectrum of the peptide precursors of an unknown protein digested with trypsin, three double charged precursors of m/z 702.81, 784.31 and 892.43 were further fragmented to obtain their MS/MS sequence spectra; (B) MS/MS spectrum of the precursor m/z 892.43, shown at the bottom of the spectrum is the sequencing result of this peptide precursor.
