EmrE defunct PDB structures 1S7B and 2F2M, and any conclusions derived from these structures, have been retracted due to a software data inversion error (Ma, 2007; Chang, 2007). Correct structures are now available. EmrE belongs to the SMR efflux pump family, DMT superfamily. EmrE accomplishes multidrug efflux by coupling conformational changes between two heterodimers with proton gradient. Dual-topology membrane protein.[4]
