    Structural mapping of oligomeric intermediates in an amyloid assembly pathway

    Theodoros K Karamanos, Matthew P Jackson ... Sheena E Radford
    Solution NMR provides structural and kinetic information about oligomers on pathway to amyloid fibrils that are precisely structured but not cytotoxic.

    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.

    Ligand modulation of sidechain dynamics in a wild-type human GPCR

    Lindsay D Clark, Igor Dikiy ... Daniel M Rosenbaum
    Generation of a highly deuterated 13C-methyl labeled wild-type GPCR sample is used to facilitate characterization of the molecular environments and fast ps-ns dynamics of sidechains when the receptor is bound to ligands of different efficacy.

    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.

    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.
