Clearly a task for SRS.

No, not the lame version in GCG 8.x - you need the real SRS for this.

1. Make a list of PDB entries in a file
2. Use this as a query (@filename) in SRS
3. Link it to SwissProt and (nagically) you have the full set of
   sequences you need:

   % getz "@filename > SWISSPROT"

I guess what you really want to do is to use PileUp to get the tree of
related sequences, rather than a full alignment - or maybe they really
do align.

Anyway, you can try further tests in SRS, like looking for PROSITE motifs
to see whether your PDB entries share a common motif - then you could
of course just align around that part.

If you have HSSP, you can also look for alignments directly from your PDB

You can try the bionet.software.srs for more help on SRS.
