TrEMBL databases or a user-entered protein sequence with a chosen enzyme, and computes the masses of the generated peptides. The tool also returns theoretical isoelectric point and mass values for the protein of interest. If desired, PeptideMass can return the mass of peptides known to carry posttranslational modifications, and can highlight peptides whose masses may be affected by database conflicts, isoforms or splicing variants.
Instructions are available.
1750 Dalton sorted by peptide masses or in chronological order in the protein.
