[bionet.molbio.genbank] Protein sequence searches on nucleotide sequence database

MICPRF@latvax8.lat.oz (07/09/90)

I am not sure if this news group takes questions but here goes -
Can the nucleic acid data bank be used to search for homologous sequences
at the protein sequence level and not just the nucleotide sequence level?
Is this publicly accessible in the way that searches at the nucleotide
sequence level are? Thanks.		Paul Fisher (micprf@latvax8.lat.oz.au).

Hi,
Your question: YES - TFASTA will take a query amino acid sequence
and translate Genbank DNA entries into 3 reading frames and score
alignments.  It's neat and it's free - written by Pearson and Lipman.

Paul,

	We have two programs on the GenBank On-line Service (GOS)
which can compare a protein sequence against the translated nucleic
acid sequence databank.  One is TFASTA as mentioned in one reply to
your message and another possibility is the IntelliGenetics program
FASTDB which will translate the nucleic acid sequence databanks in up
to six frames during the search.

	Both of these programs are available on GOS, but only to
interactive users of the system (not by e-mail).  The GenPept database
is available free of charge from genbank.bio.net by anonymous FTP.
That databank contains translation of all annotated coding regions in
GenBank.  Also note that GenPept and the GenBank and EMBL databases
are updated daily with the latest sequence data.

This is a note to thank publicly the several people who responded to my
query. The responses here cover it fairly well, but Bill Pearson was kind
enough to email me more detailed info. I would be happy to send this on to
anyone who may be interested, to save Bill the trouble. (Bill, I assume
you don't mind).		Thanks,   Paul Fisher.
