    A single K+-binding site in the crystal structure of the gastric proton pump

    Kenta Yamamoto et al.
    Crystal structures provide structural rationales for the transport stoichiometry of the gastric proton pump, which suffices the energy requirement for the generation of a million-fold proton gradient across the membrane.

    Coupling of remote alternating-access transport mechanisms for protons and substrates in the multidrug efflux pump AcrB

    Thomas Eicher et al.
    A transport mechanism is uncovered in the major drug-efflux system in E. coli involving two remote alternating-access conformational cycles, which could provide the basis for the development of allosteric inhibitors against multidrug resistance.

    Clathrin coat controls synaptic vesicle acidification by blocking vacuolar ATPase activity

    Zohreh Farsi et al.
    Parallel measurements of pH gradient and membrane potential at the single vesicle level have revealed that the synaptic vesicle acidification is initiated by removal of its clathrin coat, which blocks vesicular ATPase activity.

    Dynamic density shaping of photokinetic E. coli

    Giacomo Frangipane et al.
    The concentration of motile bacteria, expressing a light-driven proton pump, can be precisely controlled in space and time by spatially modulating their swimming speeds with a structured light pattern.

    2018 Gairdner Awards: The past, present and future of light-gated ion channels and optogenetics

    Sheena A Josselyn
    Research into light-gated ion channels called channelrhodospins laid the foundations for the development of optogenetics, a technique that has gone on to revolutionize neuroscience.
