_______________________________________________Hi all,
We have been finalising a structure with a ligand complexed to heme. I have been checking the close to final structure and I noticed that the ligand looks distorted away from what one would expect. We use Phenix.refine
We initially used the grade server for our restraints files. I also just used elbow to generate a new one. Looking at both, the restraints look reasonable (similar in both) however the initial output pdb from elbow is distorted further. The angles /lengths looked reasonable and are similar to small molecule structures (CCDC).
The planarity of a bi-phenyl moiety is very distorted.
Are we missing something?
Do we need to tell phenix.refine to not over refine the model?
Should elbow give a distorted model?
Apologies if this is all online but my uni cant seem to access phenix.org!
Thanks in advance
Joel
