Informations about Sequence Databases

General databases

Nucleotide sequence databases:

nt: nucleotide sequence database, with entries from all traditional divisions of GenBank, EMBL, and DDBJ excluding bulk divisions (gss, sts, pat, est, and htg divisions. wgs entries are also excluded. Not non-redundant.

est: EST division of GenBank, EMBL,and DDBJ

gss: GSS division of GenBank, EMBL,and DDBJ

htgs: HTG division of GenBank, EMBL,and DDBJ

env_nt: Enviromental samples database

Protein sequence databases:

nr: non-redundant protein sequence database with entries from GenPept, Swissprot, PIR, PDF, PDB, and NCBI RefSeq

env_nr: enviromental samples database

Specialized Databases
