This server allow user to predict SAM binding residues in a protein by mapping known peptides that contains SAM interacting central residue. We compute probabiliy (between 0 to 9) of each tri and penta peptides contains SAM interacting central residues from known protein structure in PDB. These tri/penta-peptides are mapped on sequence submitted by user as well propensity in range 0 to 9 also mapped. Based on propensity, server predict a residue SAM interacting or non-interacting. If propensity of a residue is more than threshold propensity selected by user then residue is assigned SAM interacting residues. This module will be useful to map known SAM binding peptide on a query protein. For more information see help page
