Dear all, Thanks for the suggestions. It is synthetic peptide so the residue identity is unambiguous. I am not clear on how to model both MET and SME in coot, do a real space refinement and then save the file for refinement in phenix. I tried alternate conformation and then mutating one of them b

Dear all, I have a peptide crystal structure at 0.97 Å that contains two surface exposed Methionine. The CE atoms of both MET have a suspiciously high b-factor >40 and a positive density. In addition, the sulfur atom SD has a large negative density (b-factor ~23). I initially suspected that the M
