THE NRSUB DATABASE - UPDATE 1997

In the context of the international project aiming at sequencing the w hole genome of Bacillus subtilis we have developed NRSub, a non-redund ant database of sequences from this organism, Starting from the B.subt ilis sequences available in the repository collections we have removed all encountered duplications, then we have added extra annotations to the sequences (e.g, accession numbers for the genes, locations on the genetic map, codon usage index), We have also added cross-references with EMBL/GenBank/DDBJ, MEDLINE, SWISS-PROT and ENZYME databases. NRSu b is distributed through anonymous FTP as a text file in EMBL format a nd as an ACNUC database, It is also possible to access the database th rough two dedicated World Wide Web servers located in France (http://a cnuc.univ-lyon1.fr/nrsub/nrsub.html) and in Japan (http://ddbjs4h.gene s.nig.ac.jp/).
