    Using light and X-ray scattering to untangle complex neuronal orientations and validate diffusion MRI

    Miriam Menzel, David Gräßel ... Marios Georgiadis
    Light and X-ray scattering on the same primate and human brain samples cross-validate each other and enable accurate mapping of axonal trajectories in regions with uni- and multi-directional nerve fibers, which can be used to validate diffusion MRI.

    The C-terminal tail of the bacterial translocation ATPase SecA modulates its activity

    Mohammed Jamshad, Timothy J Knowles ... Damon Huber
    The interaction of SecA with its substrate proteins is regulated by its evolutionarily conserved C-terminal tail, which autoinhibits SecA unless SecA binds to the ribosome.

    Conformational and oligomeric states of SPOP from small-angle X-ray scattering and molecular dynamics simulations

    F Emil Thomasen, Matthew J Cuneo ... Kresten Lindorff-Larsen
    Self-association of speckle-type POZ protein (SPOP), a substrate adaptor in the ubiquitin proteasome system, is studied by combining small-angle X-ray scattering and molecular dynamics simulations to reveal the structure of the protein assemblies in solution.

    Lactoferricins impair the cytosolic membrane of Escherichia coli within a few seconds and accumulate inside the cell

    Enrico F Semeraro, Lisa Marx ... Georg Pabst
    The damage of the bacterial cell envelope is found to be only a secondary effect of the antimicrobial activity of lactoferricin derivatives.

    Allosteric activation of the nitric oxide receptor soluble guanylate cyclase mapped by cryo-electron microscopy

    Benjamin G Horst, Adam L Yokom ... Michael A Marletta
    The full-length structures of the mammalian nitric oxide receptor reveal the molecular activation steps and a binding site for the prototype of FDA-approved stimulators.

    RNA-guided assembly of Rev-RRE nuclear export complexes

    Yun Bai, Akshay Tambe ... Jennifer A Doudna
    Tertiary folding of the Rev-response element (RRE) in HIV RNA ensures the rapid formation of the Rev-RRE viral ribonucleoprotein particle via a two-step process.

    Structure and dynamics of a nanodisc by integrating NMR, SAXS and SANS experiments with molecular dynamics simulations

    Tone Bengtsen, Viktor L Holm ... Kresten Lindorff-Larsen
    Molecular simulations, small-angle X-ray and neutron scattering experiments and previously measured NMR experiments were combined to study the structure and dynamics of the proteins and lipids in a nanodisc.

    Drastic changes in conformational dynamics of the antiterminator M2-1 regulate transcription efficiency in Pneumovirinae

    Cedric Leyrat, Max Renner ... Jonathan M Grimes
    A combination of X-ray crystallography, molecular dynamics and small angle X-ray scattering shows that the transcription antiterminator M2-1 is a structurally dynamic homotetramer that undergoes large concerted conformational changes upon binding its target RNA.

    Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

    Richard B Cooley, John P O’Donnell, Holger Sondermann
    Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.

    Insights into herpesvirus assembly from the structure of the pUL7:pUL51 complex

    Benjamin G Butt, Danielle J Owen ... Stephen C Graham
    A conserved viral protein complex that promotes membrane wrapping of nascent herpesvirus particles shows structural similarity to cellular membrane-remodelling proteins, suggesting functional mimicry.
