Hi, I had this exact same problem recently! The 'best' two solutions I
finally found were;

1) Use SRS to map from RefSeq -> uniPark -> SwissProt

(can't find where to get unipark from directly)

2) Use SeqHound to get SwissProt from GI.

I was shown the SRS method, e.g.

http://srs.ebi.ac.uk/srsbin/cgi-bin/wgetz?[UNIPARC-refdbi:NP_001102]%3ESWISSPROT


And I got the following instructions on the use of SeqHound...

If you want a list of GI's that have *exactly* the same sequence as your
input protein GI, then you could use
                                                                                
'SHoundRedundantGroup'

http://www.blueprint.org/seqhound/api_help/apifunctsdet.html#SHoundRedundantGroup
                                                                                
The Perl version of this takes a GI as input and then returns a list of
GI's.  You could use SHoundSeqIDFromGi (or SHoundSeqIDFromGiList) to find
the Swiss-Prot sequence.


Using either of these should get you a full mapping. Let me know how you
get on, 


Dan.
