β-Barrel TransMembrane Search Tool


BLAST searches using the bbTM scoring matrices against the NR-NCBI database.


>Transmembrane fragment search for structures of beta barrel membrane proteins with a solved structure using the bbTMout matrix:


>Transmembrane fragment search for human mitochondrial beta-barrel membrane proteins:


> Provide your own transmembrane segment.
Minimal sequence length: 20 amino acids. FASTA format required. Example of FASTA format:

>name of the sequence

Job submitted: please be patient while BLAST runs

(The NCBI non-redundant database is very large... and our computational power very limited)
