Available BLAST programs

Both the NCBI-BLAST and WU-BLAST suite contain the following programs :

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 is extremely slow and cpu-intensive
