Welcome to Advance Modification Module for Experts

A user can submit the sequence in the box provided below. If a sequence contains modified residues, then user can replace that particular amino acid in that sequence with default Glycine residue and select that particular modified amino acid from the respective modified residues and give their position in the box provided in front of them.
