Table 1 BLAST programs
From: Having a BLAST with bioinformatics (and avoiding BLASTphemy)
Program | Query sequence type | Target sequence type | Â |
|---|---|---|---|
BLASTP | Protein | Protein | Compares an amino acid query sequence against a protein sequence database |
BLASTN | Nucleotide | Nucleotide | Compares a nucleotide query sequence against a nucleotide sequence database |
BLASTX | Nucleotide (translated) | Protein | Compares a nucleotide query sequence translated in all reading frames against a protein sequence database |
TBLASTN | Protein | Nucleotide (translated) | Compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames |
TBLASTX | Nucleotide (translated) | Nucleotide (translated) | Compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database |
