Family: RND superfamily, AcrB/AcrD/AcrF familySequence: FASTA
Cross-database IDs: Link
Organism: Pseudomonas aeruginosa (strain ATCC 15692/PAO1/1C/PRS 101/LMG 12228)Location: Chromosome
Compound: Triclosan [class: Phenolic compounds], n-hexane [class: Alkane], p-xylene [class: Aromatic hydrocarbons]Description: Multidrug resistance protein MexB; The inner membrane transporter component of the MexAB-OprM efflux system that confers multidrug resistance. Also functions as the major efflux pump for n-hexane and p-xylene efflux. Over-Expression of the pump increases antibiotic and solvent efflux capacities. Implicated in the secretion of the siderophore pyoverdine; The ability to Export antibiotics and solvents is dramatically decreased in the presence of the proton conductor carbonyl cyanide m-chlorophenylhydrazone (CCCP), showing that an energized inner membrane is required for efflux. It is thought that the MexB subunit is a proton antiporter.
