    Revealing an outward-facing open conformational state in a CLC Cl/H+ exchange transporter

    Chandra M Khantwal et al.
    The characterization of a previously unidentified “outward-facing open” conformational state provides a new framework for understanding the CLC transport mechanism.

    Mechanism of environmentally driven conformational changes that modulate H-NS DNA-bridging activity

    Ramon A van der Valk et al.
    The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

    A putative ATPase mediates RNA transcription and capping in a dsRNA virus

    Xuekui Yu et al.
    Atomic structures suggest a novel mechanism for the regulation of mRNA transcription and capping in dsRNA viruses.

    pH- and sodium-induced changes in a sodium/proton antiporter

    Cristina Paulino, Werner Kühlbrandt
    Sodium ions but not protons induce defined helix movements in a sodium/proton antiporter and suggest a mechanism for Na + binding and transport.

    High temperature sensitivity is intrinsic to voltage-gated potassium channels

    Fan Yang, Jie Zheng
    Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.

    Molecular mechanism of thermosensory function of human heat shock transcription factor Hsf1

    Nikolai Hentze et al.
    Heat-induced local unfolding allows Hsf1 to form trimers and bind to DNA, which depends on Hsf1 concentration and is promoted, not inhibited, by Hsp90.

    Sequential conformational rearrangements in flavivirus membrane fusion

    Luke H Chao et al.
    The West Nile Virus envelope protein catalyzes membrane fusion through low-pH induced conformational rearrangement, with a rate determined by the formation of two trimeric complexes at the contact zone between the virus and target membrane.

    FcγRIIB-I232T polymorphic change allosterically suppresses ligand binding

    Wei Hu et al.
    A single-nucleotide I232T polymorphic change in FcγRIIB's transmembrane domain bends FcγRIIB's ectodomains toward cell membrane to allosterically hinder FcγRIIB's ligand association, providing novel molecular mechanism for functional loss of FcγRIIB-I232T.

    Structure of a type IV pilus machinery in the open and closed state

    Vicki AM Gold et al.
    Electron cryo-tomography reveals a huge conformational change in the secretin domain of the type IV pilus machinery that occurs when the channel opens for pilus extrusion.
