Fig. 4. A potential mechanism for proton-dependent drug
translocation by EmrE. For clarity, only the three putative
gating helices (A1, A2, and B1) and two membrane-embedded Glu-14
side chains are shown explicitly. Drug substrates and protons
are represented by the yellow sphere and red balls,
respectively.
