    Insights into the molecular architecture and histone H3-H4 deposition mechanism of yeast Chromatin assembly factor 1

    Paul Victor Sauer, Jennifer Timm ... Daniel Panne
    The CAF1 complex binds single histone H3-H4 dimers, and two such complexes associate with extended DNA elements to ensure the deposition of H3-H4 tetramers, the first step in the assembly of nucleosomes.

    An allosteric transport mechanism for the AcrAB-TolC multidrug efflux pump

    Zhao Wang, Guizhen Fan ... Dijun Du
    The tripartite drug efflux pump AcrA-AcrB-TolC, representative of a wide group of pumps from Gram-negative bacteria, enters a transport-competent state through long-distance conformational changes that switch the channel from a closed to an open state.

    Competition between Tropomyosin, Fimbrin, and ADF/Cofilin drives their sorting to distinct actin filament networks

    Jenna R Christensen, Glen M Hocky ... David R Kovar
    Both cooperative and competitive associations of actin binding proteins with actin filaments help drive the self-organization of functionally diverse F-actin networks in fission yeast.

    Structural insights into the molecular mechanisms of myasthenia gravis and their therapeutic implications

    Kaori Noridomi, Go Watanabe ... Lin Chen
    Autoantibodies from myasthenia gravis patients bind a common core region on the nicotinic acetylcholine receptor through a largely conserved mechanism.

    Dissection of the interaction between the intrinsically disordered YAP protein and the transcription factor TEAD

    Yannick Mesrouze, Fedir Bokhovchuk ... Patrick Chène
    A structure-function analysis of the YAP:TEAD interaction permits a thermodynamic mapping of this interface.

    Identification of a pre-active conformation of a pentameric channel receptor

    Anaïs Menny, Solène N Lefebvre ... Pierre-Jean Corringer
    Allosteric reorganizations of a bacterial channel receptor are mapped along the protein structure, using the site-directed bimane quenching fluorescence technique, through parallel real-time conformational and electrophysiological recordings.

    Structural reorganization of the chromatin remodeling enzyme Chd1 upon engagement with nucleosomes

    Ramasubramanian Sundaramoorthy, Amanda L Hughes ... Tom Owen-Hughes
    Structural models of the chromatin remodeling enzyme Chd1 in solution and when bound to chromatin indicate that conformational changes to both the enzyme and the nucleosome occur upon nucleotide dependent engagement.

    Elucidation of the anti-autophagy mechanism of the Legionella effector RavZ using semisynthetic LC3 proteins

    Aimin Yang, Supansa Pantoom, Yao-Wen Wu
    Legionella effector RavZ evades host autophagy by extracting LC3-PE from the membrane before deconjugation.

    Bacterial flagella grow through an injection-diffusion mechanism

    Thibaud T Renault, Anthony O Abraham ... Marc Erhardt
    Single cell, fluorescent microscopy and mathematical modeling reveal how bacterial flagella dynamically assemble outside the cell.

    Structural basis of transcription arrest by coliphage HK022 Nun in an Escherichia coli RNA polymerase elongation complex

    Jin Young Kang, Paul Dominic B Olinares ... Seth A Darst
    Cryo-electron microscopy structures show how coliphage HK022 Nun blocks Escherichia coli RNA polymerase translocation by mediating multiple interactions between the RNA polymerase and nucleic acids.
