Programs available for the BLAST search


The NCBI BLAST family of programs includes:

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

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 tblastx program cannot be used with the nr database on the BLAST Web page.
