Abstract
The present invention relates to a mass spectrometric method for determining isomeric amino acid residues of a peptide and comprises the steps of: generating a list of peptide candidates using the amino acid lead sequence of the peptide, said lead sequence comprising positions of determined amino acid residues and at least one position with undetermined isomeric amino acid residues; predicting the collision cross section for each peptide candidate; comparing the predicted collision cross section of each peptide candidate with an experimentally determined collision cross section of the peptide and assigning the isomeric amino acid residues of the best matching peptide candidate to the isomeric amino acid residues of the peptide.
