Tagging

Peptide Mass (neutral):  [Da] within mass range 

Peptide sequence tag:   'X' can be used to mean 'any amino acid'.

 Search for all possible tag permutations.
 Display only the sequences matching the tag.
 Include scan of your tag against all fragments
      in SWISS-PROT/TrEMBL matching your OS/OC
      (and KW terms for SWISS-PROT only).

 Display the predicted of the protein.
