Subject:	Re: CCL:Utility to superimpose pdb files

Dear David,

One thing is not clear from your question: Do the two PDB files represent the
same protein and
hence have the same number of (say C-alpha) atoms. If this is the case then the
CCL archives
have a program called Quatfit which could surely do this job, although I have not
yet used it for
this purpose.

If they are different proteins rather than different conformations Quatfit could
still be used but
you would need an alignment to establish the atom correspondance.

If you have want to align a given protein structure against those in PDB then try
the DALI
server at
        http://www2.ebi.ac.uk/dali/

Hope this helps.
