    Efficient conversion of chemical energy into mechanical work by Hsp70 chaperones

    Salvatore Assenza et al.
    A multiscale modeling approach reveals how the energy from ATP hydrolysis is used by Hsp70 chaperones to remodel the conformation of their substrates through a novel force-generating mechanism.

    Inducing conformational preference of the membrane protein transporter EmrE through conservative mutations

    Maureen Leninger et al.
    Conservative mutations within a secondary active transport protein influenced the conformational equilibrium probed using NMR spectroscopy which correlated to the functional output in vivo.

    Allosteric conformational ensembles have unlimited capacity for integrating information

    John W Biddle et al.
    The effective higher-order binding cooperativities arising from an ensemble of dynamically interchanging conformations are identified and shown to fully describe integration of binding information at thermodynamic equilibrium.

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

    Cedric Leyrat et al.
    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.

    Allosteric communication in class A β-lactamases occurs via cooperative coupling of loop dynamics

    Ioannis Galdadas et al.
    A combination of equilibrium and nonequilibrium molecular dynamics simulations is an effective tool to study allosteric communications in ultrafast enzymes that show little or no conformational changes.

    Defining the function of OmpA in the Rcs stress response

    Kilian Dekoninck et al.
    In vivo and in vitro approaches uncover a new function for the β-barrel OmpA and reveal how it interacts with the stress sensor lipoprotein RcsF.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

    Kinetic mechanism of coupled binding in sodium-aspartate symporter GltPh

    SeCheol Oh, Olga Boudker
    Sodium ions control the rates of both substrate binding and dissociation of an archaeal homologue of glutamate transporters in a manner that minimizes binding intermediates and maximizes transport efficiency.

    Complexin induces a conformational change at the membrane-proximal C-terminal end of the SNARE complex

    Ucheor B Choi et al.
    Complexin can have two conformations when bound to a ternary SNARE complex, one of which induces a conformational change of the SNARE complex at the C-terminus.
