    How IGF-1 activates its receptor

    Jennifer M Kavran, Jacqueline M McCabe ... Daniel J Leahy
    Ligand binding to the ectodomain of the insulin-like growth factor receptor destabilises an autoinhibitory inter-subunit interaction, which allows the transmembrane domains to associate and the intracellular regions to autophosphorylate.

    Structure of catalase determined by MicroED

    Brent L Nannenga, Dan Shi ... Tamir Gonen
    Building on previous work (Shi et al., 2013), we have used MicroED to determine the structure of catalase at 3.2 Å resolution from a single crystal.

    Conserved mechanisms of microtubule-stimulated ADP release, ATP binding, and force generation in transport kinesins

    Joseph Atherton, Irene Farabella ... Carolyn A Moores
    Cryo-electron microscopy reconstructions of two microtubule-bound transport kinesins at 7 Å resolution reveal how microtubule track binding stimulates ADP release, primes the active site for ATP binding and enables force generation.

    A Ras-like domain in the light intermediate chain bridges the dynein motor to a cargo-binding region

    Courtney M Schroeder, Jonathan ML Ostrem ... Ronald D Vale
    The dynein light intermediate chain is a member of the G protein superfamily and links the motor to several intracellular cargo adaptors.

    Analysis of the crystal structure of an active MCM hexamer

    Justin M Miller, Buenafe T Arachea ... Eric J Enemark
    Building on previous work (Froelich et al., 2014), we present the X-ray crystal structure of an active MCM hexamer, which suggests a mechanism for MCM regulation and demonstrates a key interaction between the major domains.

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

    Thomas Eicher, Markus A Seeger ... Klaas M Pos
    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.

    How lamina-associated polypeptide 1 (LAP1) activates Torsin

    Brian A Sosa, F Esra Demircioglu ... Thomas U Schwartz
    LAP1 adopts an AAA+ like fold that, while unable to bind nucleotide, can enhance ATPase activity in the neighboring TorsinA protomer in an unusual heterohexameric ring, via an arginine finger.

    Common intermediates and kinetics, but different energetics, in the assembly of SNARE proteins

    Sylvain Zorman, Aleksander A Rebane ... Yongli Zhang
    The energy landscape of SNARE folding and assembly is optimized for efficient stage-wise membrane fusion.
