FindMod tool

If your protein is not in Swiss-Prot or TrEMBL, please specify (if known) the source of your protein:
Eukaryote or Prokaryote or Archaebacteria or Virus ( Phage).

(This information will be used to determine whether certain post-translational modifications are likely to occur in your sequence.)

Check all or unmatching peptides for the following:

potential post-translational modifications (max. 1 2 within one peptide)
single amino acid substitutions.

If you wish to take into account other post-translational modifications than those already predictable by FindMod, you can specify them here:

	modification name	amino acids this modification can be observed on	atom composition
