BL2SEQ

BL2SEQ uses BLAST to find local alignments between exactly two sequences. Bl2seq is a part of NCBI's BLAST (Basic Local Alignment Search Tool) suite. It performs a comparison between any two sequences provide by the user.
The following BLAST options are available:

  • blastp compares two protein sequences
  • blastn compares two nucleic acid sequences
  • blastx compares the six-frame conceptual translation products of a nucleic acid sequence with a protein sequence
  • tblastn compares a protein sequence with the six-frame conceptual translation products of a nucleic acid sequence
  • tblastx compares the six-frame translations of a nucleic acid sequence with the six-frame translations of a nucleic acid sequence.
