    I want to get an evolutionary analysis by using NCBI NR database and Uniport database. But NR database has only blastdb and fasta format in which I can not find the taxon information. How can I get the NCBI NR database in genbank format.Thanks.
NCBI does not provide the NR database in GenBank format.

Alternatively, you could try the NCBI taxonomy database:

ftp://ftp.ncbi.nlm.nih.gov/pub/taxonomy/

The taxdump.* are taxonomy database dumps and the detail introduction is available at: ftp://ftp.ncbi.nlm.nih.gov/pub/taxonomy/taxdump_readme.txt.

The [accession2taxi][1]d folder provided the Accession number - taxonomy id relationships. You might also be interested in the gi_taxid_* files, which provide GI - taxonomy id relationship. But GenBank will not support GI soon.
