SEQUEST proteomic database

Gene names, predicted pi, and moleculai mass values are from the Yeast Proteome Database (YPD) (13). Peptide sequences were identified automatically and verified manually by using SEQUEST (12). ... [Pg.17]

A complementary approach to protein identification is based on peptide seqnencing analysis (PSA) by collision-induced dissociation (CID) in MS-MS. Por proteomics studies, the de novo sequencing of MS-MS spectra is too time-consuming. Therefore, algorithms have been developed to either provide antomated MS-MS spectmm interpretation, or perform protein identification by means of a SEQUEST database search [6-7]. In the latter case, the precursor m/z values are matched against a virtual digestion of all the proteins in the database. Sequence ions are predicted for the peptides that match the precnrsor m/z values, and compared with the measured MS-MS data. A correlation score is calculated for each match. [Pg.496]
