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

blastx

compares a nucleotide query sequence translated in all reading frames against a protein sequence database

---

There are some other blast search programs available at NCBI but due to the compatability issues of BacMet protein sequence databases to these search programs, blastn, tblastn and tblastx were not included in the user interface options.

blastn

compares a nucleotide query sequence against a nucleotide 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.
