BLAST = Basic Local Alignment Search Tool Designed to take protein and nucleic acid sequences and compare them against a selection of NCBI databases. BLAST Entry Page: http: //www. ncbi. nlm. nih. gov/blast/Blast. cgi

Selecting the BLAST Program blastp Compares an amino acid query sequence against a protein sequence database. blastn Compares a nucleotide query sequence against a nucleotide sequence database. blastx Compares a nucleotide query sequence translated in all reading frames against a protein sequence database. You could use this option to find potential translation products of an unknown nucleotide sequence.

Selecting the BLAST Program tblastn Compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames. tblastx Compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database. Please note that the tblastx program cannot be used with the nr database on the BLAST Web page because it is computationally intensive.

Arquivos BLAST (Proteínas) nr All non-redundant Gen. Bank CDS translations+PDB+Swiss. Prot+PIR+PRF month All new or revised Gen. Bank CDS translation+PDB+Swiss. Prot+PIR released in the last 30 days. swissprot The last major release of the SWISS-PROT protein sequence database (no updates). These are uploaded to our system when they are received from EMBL.

Arquivos BLAST (Proteínas) patents Protein sequences derived from the Patent division of Gen. Bank. Yeast (Saccharomyces cerevisiae) protein sequences. This database is not to be confused with a listing of all Yeast protein sequences. It is a database of the protein translations of the Yeast complete genome. E. Coli E. coli (Escherichia coli) genomic CDS translations. PDB Sequences derived from the 3 -dim structure Brookhaven Protein Data Bank.

Arquivos BLAST (DNA) nr All non-redundant Gen. Bank+EMBL+DDBJ+PDB sequences (but no EST, STS, GSS, or HTGS seqs). month All new or revised Gen. Bank+EMBL+DDBJ+ PDB sequences released in the last 30 days. dbest Non-redundant database of Gen. Bank+EMBL+DDBJ EST Divisions. mouse ests The non-redundant Database of Gen. Bank+EMBL+DDBJ EST Divisions limited to the organism mouse.

Arquivos BLAST (DNA) human ests The Non-redundant Database of Gen. Bank+EMBL+DDBJ EST Divisions limited to the organism human. other ests The non-redundant database of Gen. Bank+EMBL+DDBJ EST Divisions all organisms except mouse and human. Yeast (Saccharomyces cerevisiae) genomic nucleotide sequences. Not a collection of all Yeast nucelotides sequences, but the sequence fragments from the Yeast complete genome.
