    Structure and transport mechanism of the sodium/proton antiporter MjNhaP1

    Cristina Paulino et al.
    The inward-open and outward-open structures of MjNhaP1 explain the mechanism of electroneutral sodium-proton antiport across the cell membrane.

    ENaC-mediated sodium influx exacerbates NLRP3-dependent inflammation in cystic fibrosis

    Thomas Scambler et al.
    Dysfunction and overexpression of ENaC-mediated sodium influx exacerbates activation of NLRP3-inflammasome mediated inflammation in cells with CF-associated mutations and is modulated by inhibition of these amiloride-sensitive sodium (Na+) channels.

    Evolution of cation binding in the active sites of P-loop nucleoside triphosphatases in relation to the basic catalytic mechanism

    Daria N Shalaeva et al.
    In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.

    Structure and substrate ion binding in the sodium/proton antiporter PaNhaP

    David Wöhlert et al.
    The X-ray structure of the PaNhaP provides a unique view of substrate-ion binding and release in electroneutral sodium/proton antiporters.

    Kinetic mechanism of coupled binding in sodium-aspartate symporter GltPh

    SeCheol Oh, Olga Boudker
    Sodium ions control the rates of both substrate binding and dissociation of an archaeal homologue of glutamate transporters in a manner that minimizes binding intermediates and maximizes transport efficiency.

    pH- and sodium-induced changes in a sodium/proton antiporter

    Cristina Paulino, Werner Kühlbrandt
    Sodium ions but not protons induce defined helix movements in a sodium/proton antiporter and suggest a mechanism for Na + binding and transport.

    Profound regulation of Na/K pump activity by transient elevations of cytoplasmic calcium in murine cardiac myocytes

    Fang-Min Lu et al.
    Transient Ca elevations of cytoplasmic calcium in cardiac myocytes profoundly activate cardiac Na/K pump activity in parallel with physical-chemical changes of the sarcolemma but without involvement of conventional signaling mechanisms.

    Intraflagellar Transport: Moving proteins along in the cilium

    Narcis Adrian Petriman, Esben Lorentzen
    The structures of the bovine and human BBSome reveal that a conformational change is required to recruit the complex to the ciliary membrane.

    Bacterial Evolution: The road to resistance

    Devon M Fitzgerald
    The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.
