Re: [ccp4bb] Thanks and outcome of ([ccp4bb] Looking for method to find similar oligomeric arrangement)

A further note on assembly search: since April the RCSB PDB offers structure search for assemblies. See the "Structure Similarity" section in https://www.rcsb.org/search/advanced. This works only for PDB-deposited structures but we are working on making it available for 3D coordinates submitted by

Dear All Many thanks to Johann for the suggestion of Topsearch - rather pleasingly our tetramer is novel in the tetrameric arrangement, but each of the dimers has its DNA recognition helices in agreement with several hits 😊a win all round Bringing joy to my lockdown. Best Andy ###

Re: [ccp4bb] Looking for method to find similar oligomeric arrangement

Thanks to all of you pointing me towards ProtCID, but unless I'm mistaken this works only for deposited co-ordinates / PDB entries? I was more looking for something that would take my (yet to be deposited) PDB file, with its inherent tetrametric hth fold, and find similar folds in similar arra

Hi Andy, Are you familiar with ProtCID? http://dunbrack2.fccc.edu/ProtCiD/Default.aspx Might be relevant. Best, Orly On Sun, Jun 21, 2020 at 12:02 AM Andrew Lovering wrote: > Dear colleagues, > > > I have a structure of a simple, common fold (hth, dna-binding) that I > believe has oligomerize

Re: [ccp4bb] Looking for method to find similar oligomeric arrangement

Thanks Boaz for the SSM heads up. I was much too DALI-centric! One last point, if anyone can offer an opinion - I presume most methods will match but only within ASU contents. Does any approach utilize deposited "biological unit" classification or (better still) crystallographic symmetry oper

Re: [ccp4bb] Looking for method to find similar oligomeric arrangement

Hi, You can try the SSM from the pdbe tools, also described in Krissinel and Henrick (2004), Acta D63, 366-380. It worked for us nicely on a similar problem of a dimeric structure. Cheers, Boaz. Boaz Shaanan, Ph.D. Department of Life Sciences Ben Gurion University of the Negev Beer Sheva Israe

[ccp4bb] Looking for method to find similar oligomeric arrangement

Dear colleagues, I have a structure of a simple, common fold (hth, dna-binding) that I believe has oligomerized in a different way to that observed for any members of the superfamily that I can reasonably analyze. So if I run fold comparison analysis (e.g. DALI) it will find similar structur
