Re: [ccp4bb] How to define the DNA bond between P and O3’ from two different symmetric units?

2018-01-30 Thread Edward A. Berry
Dear Peng, The choice of asymmetric unit is somewhat arbitrary. Please forgive me and ignore this if I am saying something obvious and you already know this does not apply in your case, but I see most of your previous posts concern EM structures, so perhaps you are relatively new to solving

Dear Nicolas, Thank you for your help. Our DNA is not a palindromic sequence, and I think it should not be degraded easily. The data can be processed in the space groups C2221, P41212 or lower, with 12bp, 6bp ,24bp or longer in one NCS. I can see the connection between two symmetric DNA

Hi Claudia, another program that I used with success is Hollow ( https://www.ncbi.nlm.nih.gov/pubmed/19014592). It is really easy to use. You can get is here http://hollow.sourceforge.net/ It finds pockets in a defined area, fills them with water molecules and generates a pdb with those waters.

Hi Claudia, For the identification of cavities and residues linning them, metapocket is one of the preferred choice as it uses prediction from various program. Output of the server is pdb file. I found caver program represent cavities in a best manner. There is caver plugin available for pymol.

Hi Claudia, Another possibility is CastP: http://sts.bioe.uic.edu/castp/index.html They also have a Pymol plugin. I have not used this plugin since I'm displaying the CastP o/p files in UCSF-chimera which handles them nicely. Cheers,             Boaz     Boaz Shaanan, Ph.D.

Hi Claudia Two options I've used recently, liked and displayed without fuss in PyMOL are ProFunc (https://www.ebi.ac.uk/thornton-srv/databases/profunc/) and Ghecom (http://strcomp.protein.osaka-u.ac.jp/ghecom/). Ghecom gives you PDB files directly. ProFunc gives you rasmol scripts but they

I am trying to convince XChemExplorer to refine my PANDDA models – i.e. those which have had ligands saved / placed into promising density. However, the large majority of refinement jobs (started by exporting all PANDDA models) simply fail. Is there a log file or something I can look at to see

Dear Peng, to me your problem sound a bit strange, except if it's a palindromic sequence. I don't understand how you can have one part of the DNA in one asymmetric unit and one in another one. My question are : maybe you considering a NCS as a true symmetry and underestimate the unit-cell
