Fig. 2.
MS/MS spectra of G6b peptides. Peptides corresponding to each MS/MS spectra are shown in the top right corner of each panel, along with the G6b isoforms from which each peptide may have been derived, the Swiss-Prot/TrEMBL accession number (in parenthesis), and the experiment and band slice identification numbers. The start and end of each peptide are indicated by dots. Adjacent amino acids to the peptide identified are also included (outside dots). Selected b- and y-ions identified are indicated. (A) Peptide TVLHVLGDR is present in all seven isoforms of G6b. (B) Pepetide LPPQPIRPLPR is only present in G6b-A. (C) Peptide IPGDLDQEPSLLYADLDHLALSR is present in G6b-B, -C and -E.
