Entrez _____________________________ "Entrez provides integrated access to nucleotide and protein sequence data from >130,000 organisms, along with 3D protein structures, genomic mapping information, PubMed MEDLINE, and more. Sequence data is combined from various sources, including GenBank, EMBL, DDBJ, RefSeq, PIR-International, PRF, Swiss-Prot, and PDB. Two unique features of Entrez are: (1) pre-computed similarity searches for each database record, identifying the related records ("neighbors") within that database. The algorithm used to identify related records depends upon the database. (2) links from a record in one database to associated records in the other Entrez databases, providing integrated access across the various databases. For exmaple, if a MEDLINE record cites a GenBank nucleotide sequence record, which in turn is linked to a protein translation, there will be a link between those three records." _____________________________ Help document Tutorial Detailed information about the individual databases |
