I am refinig a structure at 2.1 A. I have 2 questions:
a) Is the best way to identify a ligand refining the protein and water
molecules and at the end looking at the 2mfo-dfc and mfo-dfc maps? Or
looking at a SA composit omit map?
b) In almost every map i look at during refinement I see density that
smears/joins my ligand (cyclopentenone type molecule) and flavin's
isoalloxazine ring. Has anyone ever seen that? they seem to be 3.1 A
apart?
Thanks
