Hello Giacomo,

There is probably more than one solution.  My first idea is to try and
use the Entrez utilities.  Have you tried searching Entrez for your
locus tag via this web page?
http://www.ncbi.nlm.nih.gov/Entrez/

If this work, then I would try using the Bio.Entrez module in
Biopython, and request the desired records in FASTA or GenBank format
according to your needs.
