Re: [ccp4bb] 3BDN, 16.5% Ramachandran Outliers!!!!!

[Dr. Mark Mayer]

Its not just the Ramachandran outliers - the attached metrics summary courtesy of the PDB raises a lot of questions about the accuracy of this structure

As for Nature being right, it was an attempt at humor.

Dear crystallographers,



<http://www.rcsb.org/pdb/explore.do?structureId=3BDN>http://www.rcsb.org/pdb/explore.do?structureId=3BDN



In preffered region: 58.04%

In allowed regions: 19.78%

Outliers: 22.17%      !!!!!!!!!




Thanks

Misbha

The PDB entry has 16.5% Ramachandran outliers. When I opened this PDB file in coot and checked for Ramachandran outliers, the results are: With an R-free of 37.4% at 3.9 A resolution, could you please tell me how reliable this structure of Lambda repressor bound to DNA is?
