| + | [[http://www.uniprot.org/uniprot/MEXA_PSEAE MEXA_PSEAE]] The periplasmic linker 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. Required for assembly of the MexA/MexB/OprM complex. Implicated in the secretion of the siderophore pyoverdine.<ref>PMID:8226684</ref> <ref>PMID:8540696</ref> <ref>PMID:9603892</ref> 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.<ref>PMID:8226684</ref> <ref>PMID:8540696</ref> <ref>PMID:9603892</ref> | ||
