A fragmentation model that probabilistically sums up the possible fragmentation routes of a given trial amino acid sequence, in accordance with a set of rules and chemical processes involved, is used to calculate the presence of the trial amino acid sequence from a processable mass spectrum, produced from a peptide or protein. A processable mass spectrum of the peptide or protein is produced. The presence of any given trial amino acid sequence which corresponds to the spectrum, is calculated using a fragmentation model, by which the fragmentation of the trial sequence, based on a set or routes, and fragmentation routes of higher probability corresponding to chemical processes involved, are summed probabilistically. An independent claim is also included for an amino acid sequence identification apparatus which has a mass spectrometer and a data processor. The data generated from the produced mass spectrum is processed of trial amino acid sequence. |
