Re: [ccp4bb] quaternary structure comparison
Dear Eike, depending on what your structure is - you can try interface search in PISA (google on "ebi pisa"). Select the most "representative" interface in your complex (the one that makes the non-standard arrangement) and see whether there are similar interfaces in the PDB. It shouldn't be a too long list, you may then shorthen it to structures with given oligomeric state and finally check them by eye. Cheers, Eugene.

In order to check whether this arrangement that I see is something new I would like to perform a quaternary structure comparison. Is there any such tool available? A Google search wasn't very conclusive. Or is there a clever combination of available resources? Kind regards Eike
Re: [ccp4bb] quaternary structure comparison
The human intelligance system "Alexey Murzin" of the LMB in Cambridge comes to mind - helpful and knowledgable about "all" known folds. Mark Quoting Roberto Steiner : Hi Eike, PISA (http://www.ebi.ac.uk/msd-srv/prot_int/pistart.html) or SCOPPI (http://www.scoppi.org ) might be useful. Interested in hearing about other alternatives.
