FindPept can identify peptides that result from unspecific cleavage of proteins from their experimental masses, taking into account artefactual chemical modifications, post-translational modifications (PTM) and protease autolytic cleavage. If you wish to take into account only specific cleavage, please use FindMod instead.
The experimentally measured peptide masses are compared with the theoretical peptides calculated from a specified UniProtKB (Swiss-Prot or TrEMBL) entry or from a user-entered sequence. If autolysis is to be taken into account, an enzyme entry must be specified from the drop-down list of enzymes for which the sequence is known.
