Nucleotide
EMBL Database	The EMBL Nucleotide Sequence Database (also known as EMBL-Bank) constitutes Europe's primary nucleotide sequence resource. Main sources for DNA and RNA sequences are direct submissions from individual researchers, genome sequencing projects and patent applications.
GenBank	GenBank® is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences
DDBJ	DDBJ (DNA Data Bank of Japan) began DNA data bank activities in earnest in 1986 at the National Institute of Genetics (NIG).
HIV Database	The HIV databases contain data on HIV genetic sequences, immunological epitopes, drug resistance-associated mutations, and vaccine trials.
IMGT	MGT, the international ImMunoGeneTics project, is a collection of high-quality integrated databases specialising in Immunoglobulins, T cell receptors and the Major Histocompatibility Complex (MHC) of all vertebrate species.
dbEST	dbEST (Nature Genetics 4:332-3;1993) is a division of GenBank that contains sequence data and other information on "single-pass" cDNA sequences, or Expressed Sequence Tags, from a number of organisms.
BERLIN	5S rRNA database
EPD	Eukaryotic Promoter database
Protein
SWISS-PROT	The UniProtKB/Swiss-Prot Protein Knowledgebase is a curated protein sequence database that provides a high level of annotation, a minimal level of redundancy and a high level of integration with other databases.
