Entrez Nucleotide database

Entrez nucleotide database, June, 2006 (http //www.ncbi.nlm.nih.gov/entrez). 

Entrez (http //www.ncbi.nlm.nih.gov/Entrez/nucleotide.html) offers 23 search fields (e.g., accession number, protein name, author, keyword, EC number). If the accession number is used, the nucleotide sequence, organism and tissue source of sequence and journal references can be obtained. Entrez also provides direct links to other databases such as PubMed. 

Entrez (http //www.ncbi.nih.gov/entrez), information retrieval system, integrating NCBI databases of protein and nucleotide sequences, genomes, macromolecular stmctures, and MEDLINE literature database. 

The NCBI s Entrez is apowerful database search engine. This integrated search engine provides a menu (http //www.ncbi.nih.gov/Entrez/index.html) offering the user selections to search biomedical literature (PubMed), databases on OMIM, nucleotide sequence, protein sequence, whole genome sequences, 3D macromolecular structures, taxonomy (organisms in GenBank), SNP,... 

The amino acid sequences of proteins and nucleotide sequences of DNA can be retrieved from the integrated database retrieval systems Entrez (http //... 

The amino acid sequences can be searched and retrieved from the integrated retrieval sites such as Entrez (Schuler et al., 1996), SRS of EBI (http //srs.ebi.ac.uk/), and DDBJ (http //srs.ddbj.nig.ac.jp/index-e.html). From the Entrez home page (http //www.ncbi.nlm.nih.gov/Entrez), select Protein to open the protein search page. Follow the same procedure described for the Nucleotide sequence (Chapter 9) to retrieve amino acid sequences of proteins in two formats GenPept and fasta. The GenPept format is similar to the GenBank format with annotated information, reference(s), and features. The amino acid sequences of the EBI are derived from the SWISS-PROT database. The retrieval system of the DDBJ consists of PIR, SWISS-PROT, and DAD, which returns sequences in the GenPept format.

Entrez, to be clear, is not a database itself—it is the interface through which all of its component databases can be accessed and traversed. The Entrez information space includes PubMed records, nucleotide and protein sequence data, three-dimensional structure information, and mapping information. The strength of Entrez lies in the fact that all of this information can be accessed by issuing one and only one query. Entrez is able to offer integrated information retrieval through the use of two types of coimection between database entries neighboring and hard links. 

Research on the galactosyltransferases over the last four decades has resulted in a wealth of information that is now easily accessible in various databases. The reader is encouraged to explore three databases in particular 1) Entrez 2) ExPASy and 3) CAZY. As detailed below, these databases contain information regarding nucleotide sequence, protein sequence and enzyme properties such as reaction catalyzed. Km, metal ion requirements, inhibitors, etc.
