GeneBee BLAST 2.2.8 Services

Nucleotide BLAST
allows one to input nucleotide sequences and compare these against other nucleotides.
Standard nucleotide-nucleotide BLAST [blastn]
Takes nucleotides sequences in FASTA format, GenBank Accession numbers or GI numbers and compares them against the NCBI nucleotide databases.

Protein BLAST
allows one to input protein sequences and compare these against other protein sequences.
Standard protein-protein BLAST [blastp]
Takes protein sequences in FASTA format, GenBank Accession numbers or GI numbers and compares them against the NCBI protein databases.

Translated BLAST Searches
These searches translate either query sequences or databases from nucleotides to proteins so that protein - nucleotide sequences can be performed.
Nucleotide query - Protein db [blastx]
Converts a nucleotide query sequence into protein sequences in all 6 reading frames. The translated protein products are then compared against the NCBI protein databases.
Protein query - Translated db [tblastn]
Takes a protein query sequence and compares it against an NCBI nucleotide database which has been translated in all six reading frames.
Nucleotide query - Translated db [tblastx]
Converts a nucleotide query sequence into protein sequences in all 6 reading frames and then compares this to an NCBI nucleotide database which has been translated in all six reading frames.
