The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.
20 Ιαν 2006 · Entrez is NCBI’s primary text search and retrieval system that integrates the literature and molecular databases at NCBI including DNA and protein sequence, structure, gene, genome, genetic variation, and gene expression. This document is an overview of the Entrez databases, with general information on searching and displaying data.
Entrez is a search system that locates/retrieves biological sequence information in the Genbank database. There are several interfaces, and we will concentrate in the web interface. This web interface has the protein and nucleic acid data, the tridimensional structures of some proteins and the full genomes in separate places.
As of December 1, 2018, all records from the databases for Expressed Sequence Tags (EST) and Genome Survey Sequences (GSS) will reside in NCBI’s Nucleotide database. This change will provide a single point of access for all GenBank sequence data with a common look and feel.
You can use Entrez query syntax to search a subset of the selected BLAST database. This can be helpful to limit searches to molecule types, sequence lengths or to exclude organisms. more...
