I am refining a 1.71A X-ray structure with phenix refine. I have everything modelled in - ~150 residues in the ASU and a heme - and my R-work/R-free is 0.17/0.22. But when I went to deposit it, PDB pointed out that two of my sidechains have distorted geometries. One is a His, and looking at it in Coot, I can clearly see the 2Fo-Fc density for the correct geometry, but the actual coordinates that phenix refine produce don't lie in that density; there are significant difference map peaks showing that the coordinates are in the wrong place. If I use real space refine in Coot to put the coordinates back into the correct density and refine it again in phenix, they get distorted again.
What settings in phenix should I check to try to get it to properly refine the coordinates?
