    Room-temperature crystallography reveals altered binding of small-molecule fragments to PTP1B

    Tamar Skaist Mehlman, Justin T Biel ... Daniel A Keedy
    Many small-molecule fragments bind differently to the allosteric protein PTP1B in room-temperature instead of cryogenic crystal structures, which may be relevant for structure-based drug design.

    Cryo-EM structures of mitochondrial respiratory complex I from Drosophila melanogaster

    Ahmed-Noor A Agip, Injae Chung ... Judy Hirst
    Structures of respiratory complex I from the insect and metazoan model system Drosophila melanogaster reveal its close relationships with the mammalian complex and provide a foundation for new approaches to disentangle mechanisms of complex I catalysis and regulation.

    Chloride ions evoke taste sensations by binding to the extracellular ligand-binding domain of sweet/umami taste receptors

    Nanako Atsumi, Keiko Yasumatsu ... Atsuko Yamashita
    Sweet and umami taste receptors are capable of sensing chloride ions, a component of table salt other than the salty taste-inducing component, sodium ions, and induce preferable taste sensations such as sweet taste.

    Structural features stabilized by divalent cation coordination within hepatitis E virus ORF1 are critical for viral replication

    Robert LeDesma, Brigitte Heller ... Alexander Ploss
    A combined computational, genetic, and biochemical analysis of the hepatitis E virus open reading frame 1 (ORF1) protein identifies a novel domain-domain interaction that is vital for fitness and supports a proposed structural model of the ORF1 polyprotein.

    Gating interactions steer loop conformational changes in the active site of the L1 metallo-β-lactamase

    Zhuoran Zhao, Xiayu Shen ... Shozeb Haider
    Extremely significant interactions between α3-β7 and β12-α5 loops in the tetrameric L1 metallo-β-lactamase play an important role in the structural remodeling of the active site and offer insights into the potential for novel drug development by exploiting these interactions.

    Structure of Dunaliella photosystem II reveals conformational flexibility of stacked and unstacked supercomplexes

    Ido Caspy, Maria Fadeeva ... Nathan Nelson
    Photosystem II, the pigment-protein complex responsible for water oxidation in photosynthesis, was found to exist in two different core conformations with altered antennae connectivity.

    Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution

    Josep Martí-Solans, Aina Børve ... Timothy Lynagh
    Expression patterns and biophysical properties of acid-sensing ion channels in numerous bilaterian animals offer insight into the deployment of ion channels by the evolving nervous system in complex animals.

    State-specific morphological deformations of the lipid bilayer explain mechanosensitive gating of MscS ion channels

    Yein Christina Park, Bharat Reddy ... José D Faraldo-Gómez
    A theory is presented that explains why some ion channels tend to open in response to membrane stretching, which posits that channel closing is disfavored by the morphological energetics of the lipid bilayer, and increasingly so under lateral tension.

    Activation-pathway transitions in human voltage-gated proton channels revealed by a non-canonical fluorescent amino acid

    Esteban Suárez-Delgado, Maru Orozco-Contreras ... Leon D Islas
    Combined patch-clamp fluorometry with ANAP, a fluorescent non-canonical amino acid, uncovers transitions in the activation pathway of human HV1 that are modulated by voltage and the pH gradient.

    Targeting RNA:protein interactions with an integrative approach leads to the identification of potent YBX1 inhibitors

    Krystel El Hage, Nicolas Babault ... David Pastré
    The development of an integrative computational-experimental approach for identifying small molecules that can disrupt RNA:protein interactions in vitro and in cells led to the identification of several inhibitors of YBX1 in the micromolar range, including a previously approved drug.
