Re: [ccp4bb] quaternary structure comparison

2009-06-16 Thread Eugene Krissinel

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.

Dear All,

I solved a structure that has a very common tertiary structure motif but it
appears as if the arrangement of the monomers is somewhat Œnon-standart¹.

Of course I performed a DALI search, which resulted in a great number of
hits  due to the similarity of the tertiary structure (Z¹s: 250 >8; 100 >
10).

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

The human intelligance system "Alexey Murzin" of the LMB in Cambridge  
comes to mind - helpful and knowledgable about "all" known folds.

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.

Best wishes
