AbeM, an H+-coupled Acinetobacter baumannii multidrug efflux pump belonging to the MATE family of transporters

We cloned a gene, abeM, for a multidrug efflux pump from Acinetobacter baumannii using Escherichia coli as the host. Sequence analysis revealed that AbeM is a member of the MATE family of pumps. AbeM was found to be an H+-coupled multidrug efflux pump and a unique member of the MATE family.
