    Non-catalytic motor domains enable processive movement and functional diversification of the kinesin-14 Kar3

    Christine Mieck, Maxim I Molodtsov ... Stefan Westermann
    The kinesin-14 motor Kar3 moves along microtubules using a previously undescribed mechanism that critically requires the presence of a non-catalytic head.

    Methylation at the C-2 position of hopanoids increases rigidity in native bacterial membranes

    Chia-Hung Wu, Maja Bialecka-Fornal, Dianne K Newman
    Methylation specifically enhances the ability of hopanoids to rigidify membranes under physiologically relevant conditions, which impacts the current interpretation of the 2-methylhopane fossil record.

    Noncanonical binding of BiP ATPase domain to Ire1 and Perk is dissociated by unfolded protein CH1 to initiate ER stress signaling

    Marta Carrara, Filippo Prischi ... Maruf MU Ali
    The chaperone protein BiP forms complexes with Ire1 and Perk that dissociate when unfolded proteins bind to BiP to activate the unfolded protein response in the ER.

    Recognition of the small regulatory RNA RydC by the bacterial Hfq protein

    Daniela Dimastrogiovanni, Kathrin S Fröhlich ... Ben F Luisi
    The regulatory RNA RydC binds to Hfq to make an effector complex for the recognition of targeted mRNA in the regulation of genetic information.

    Cofilin-induced unidirectional cooperative conformational changes in actin filaments revealed by high-speed atomic force microscopy

    Kien Xuan Ngo, Noriyuki Kodera ... Taro QP Uyeda
    A cluster of cofilin along an otherwise bare actin filament induces distinctively asymmetric cooperative conformational changes to the filament on either side of the cluster.

    Structure of a low-population intermediate state in the release of an enzyme product

    Alfonso De Simone, Francesco A Aprile ... Michele Vendruscolo
    Product release from human lysozyme is mediated by an intermediate state with transient weak interactions between the product and enzyme.

    A novel N-terminal extension in mitochondrial TRAP1 serves as a thermal regulator of chaperone activity

    James R Partridge, Laura A Lavery ... David A Agard
    Cytosolic and organellar Hsp90s from higher eukaryotes have evolved a variable, and environmentally responsive N-terminal extension to regulate their activity.

    Sequential conformational rearrangements in flavivirus membrane fusion

    Luke H Chao, Daryl E Klein ... Stephen C Harrison
    The West Nile Virus envelope protein catalyzes membrane fusion through low-pH induced conformational rearrangement, with a rate determined by the formation of two trimeric complexes at the contact zone between the virus and target membrane.

    Native architecture of the Chlamydomonas chloroplast revealed by in situ cryo-electron tomography

    Benjamin D Engel, Miroslava Schaffer ... Wolfgang Baumeister
    The first 3D views of the native algal chloroplast provide new insights into thylakoid biogenesis, photosynthesis, and carbon fixation.
