From: [email protected] [mailto:[email protected]] On Behalf Of Aaron Oakley Sent: Thursday, February 1, 2018 4:37 AM To: [email protected] Subject: [phenixbb] side-chain on special position. Hello fellow Phenix-ers, I have a structure I am trying to finish in Phenix.refine The is one problem: a glutamate residue sitting on a crystallography 2-fold axis with partial occupancy (picture attached). This residue and its symmetry mate appear to take turns sitting at this position: filling the density leads to severe collision with its symmetry mate. Building the side-chain with occupancy 0.5 doesn’t seem to help, as the residue is pushed out of density during refinement. Any work-arounds? Thanks all, Aaron [cid:[email protected]]
