    Coupled ion binding and structural transitions along the transport cycle of glutamate transporters

    Grégory Verdon et al.
    Crystal structures of an archaeal homologue of mammalian glutamate transporters in apo and ion-only bound outward- and inward-facing states reveal ion-coupled conformational changes supporting mechanisms of coupling, gating, and transport.

    The metal transporter ZIP13 supplies iron into the secretory pathway in Drosophila melanogaster

    Guiran Xiao et al.
    Drosophila ZIP13 (Slc39a13), a presumed zinc importer, is responsible for iron delivery to the secretory pathway.

    Preacinetobactin not acinetobactin is essential for iron uptake by the BauA transporter of the pathogen Acinetobacter baumannii

    Lucile Moynié et al.
    The pathogen Acinetobacter baumannii recognises preacinetobactin not acinetobactin, yet appears likely to translocate both compounds through a mixed complex.

    Real time dynamics of Gating-Related conformational changes in CorA

    Martina Rangl et al.
    High-speed atomic force microscopy reveals that the open state of the divalent ion channel CorA is highly dynamic and defined by the fast exchange between conformations.

    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.

    The ER membrane protein complex interacts cotranslationally to enable biogenesis of multipass membrane proteins

    Matthew J Shurtleff et al.
    The ER membrane protein complex promotes the biogenesis of a subset multipass membrane proteins enriched for transporters and other proteins with destabilizing features in transmembrane domains.

    Helical jackknives control the gates of the double-pore K+ uptake system KtrAB

    Marina Diskowski et al.
    The K(+) uptake system KtrAB is controlled by an allosteric mechanism entirely new for membrane channels, which operates the channel gate over a 35 Å distance.
