Re: [ccp4bb] torsion restraints and phi/psi

If memory serves correctly Ramachandran based his plot on VDW. Therefore all programs which use VDW will tend to put residues in the right place. Certainly in phenix.refine adding H's to one of my problematic structures (twinning) not only improved the clash score but pushed a further 4% into th

[ccp4bb] TLSANAL

I have a multidomain multimeric protein. I would be interested to see if the TLS parameters correlate with some functional data. TLSANAL tanks with overlap error (no overlap that I am aware of). I fed it tls file and final pdb. Does anyone know any other way to interpret TLS parameters? (preferabl

[ccp4bb] Low resol structure

Dear All, I have an interesting problem, we have a 3.45A structure of a membrane protein. We have just been told that the structure is "too low resolution to be considered as the uncertainty is too high". We use the structure to identify helices which have moved. Is there a blanke

[ccp4bb] restrain water metal distance

I have a metal centre and I have constructed my dictionary. What I cannot do is restrain the metal to water distance. All my amino acid links are working. However even though I have created the dictionary and put the link in PDB header REFMAC ignores it and pushes the water back to 2.45A (rather th

[ccp4bb] NAp dictionary

I don't know how many of you are frustrated with AO5* in NADP NAP (and in NAD). I trolled the web looking for a solution but did not find it. I think I have converted the current NAP nomenclature from the EBI in REFMAC and COOT to use the new agreed nomenclature for this residue. Simply replace yo

Dear All, Thanks to many of you who posted comments and suggestions. The review process concluded on our paper. I will try to distil the suggestions I found useful with some comments from my own experience. 1 Do not be put off by editor, argue for a technical review in advance of
