    Dynamic basis of lipopolysaccharide export by LptB2FGC

    Marina Dajka, Tobias Rath ... Benesh Joseph
    LptC regulates the LPS entry gate in LptB2FG, likely through a dynamic behavior of its transmembrane helix, while the β-jellyroll domains are tethered in the periplasm.

    Dynamic allostery in substrate binding by human thymidylate synthase

    Jeffrey P Bonin, Paul J Sapienza, Andrew L Lee
    The mechanism of substrate binding cooperativity in human thymidylate synthase does not derive from millisecond dynamic interconversion between active and inactive conformations in solution, but instead results primarily from differential changes in faster side-chain motions (conformational entropy), facilitated by a disordered N-terminus.

    Hsp40s play complementary roles in the prevention of tau amyloid formation

    Rose Irwin, Ofrah Faust ... Rina Rosenzweig
    Chaperones from different families and classes synergistically target different stages of tau aggregation, thus preventing pathological amyloid formation.

    Structural intermediates observed only in intact Escherichia coli indicate a mechanism for TonB-dependent transport

    Thushani D Nilaweera, David A Nyenhuis, David S Cafiso
    Pulse electron paramagnetic resonance on intact Escherichia coli reveals a substrate-induced structural transition in BtuB, the vitamin B12 transporter, which is not seen in reconstituted membranes and indicates a mechanism of transport.

    Structural basis for allosteric control of the SERCA-Phospholamban membrane complex by Ca2+ and phosphorylation

    Daniel K Weber, U Venkateswara Reddy ... Gianluigi Veglia
    A spectroscopic analysis of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)-phospholamban membrane complex reveals the importance of the relative transmembrane orientation for inhibition or activation of the ATPase.

    The frequency gradient of human resting-state brain oscillations follows cortical hierarchies

    Keyvan Mahjoory, Jan-Mathijs Schoffelen ... Joachim Gross
    The strongest peak frequency of brain oscillations in a brain area decreases significantly, gradually and robustly along the posterior-anterior axis following the global hierarchy from early sensory to higher order areas.

    Local frustration determines loop opening during the catalytic cycle of an oxidoreductase

    Lukas S Stelzl, Despoina AI Mavridou ... Christina Redfield
    The cysteine pair oxidation state in nDsbD acts as a ‘switch’ controlling the presence or absence of frustration in the active-site and determining the dynamic behavior of the cap loop.
