Hi Yasser, Sorry, mutation with the Rotamers tool (or swapaa command) is only to L-amino acids. Some less convenient alternatives: - use Build Structure (under Tools... Structure Editing) to build out the D- side chain manually. Note the resulting bond lengths and angles are approximate. - open another structure that contains the D- amino acid, match the backbone atoms of the residue you wish to substitute, write out coordinates "relative to" the first structure, then manually edit the PDB file to substitute that sidechain for the one originally in the structure. I hope this helps, Elaine ----- Elaine C.

Can Chimera mutate by D-residues? If this is possible, how i can do it?
