Hi all, I'm using phenix.refine to refine a structure of a Molybo-protein at 1.9Å. The MGD cofactors (molybdopterin guanine dinucleotide) are being refined with a weird distorted geometry causing some clashes. The Fo-Fc maps show that something is going wrong in the aromatic rings interatomic distances. I'm using the readyset to pick up MGD and metal restraints. Am I using the right protocol?
