    Discovery and characterization of Hv1-type proton channels in reef-building corals

    Gisela Rangel-Yescas, Cecilia Cervantes ... Leon D Islas
    Proton channels are present in reef-building corals and constitute important molecular players that should help understand calcification and the response of these organisms to ocean acidification.

    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.

    Development of antibacterial compounds that constrain evolutionary pathways to resistance

    Yanmin Zhang, Sourav Chowdhury ... Eugene Shakhnovich
    Integrated multi-scale, multi-tool approach to design novel 'evolution drugs' which can delay the emergence of antibiotic resistance by constraining bacterial evolutionary escape strategies.

    Homo-oligomerization of the human adenosine A2A receptor is driven by the intrinsically disordered C-terminus

    Khanh Dinh Quoc Nguyen, Michael Vigers ... Songi Han
    The C-terminus of A2A receptor drives oligomer formation via an intricate network of disulfide bonds, hydrogen bonds, electrostatic interactions, and hydrophobic interactions, all of which are enhanced by depletion interactions.

    Structurally distributed surface sites tune allosteric regulation

    James W McCormick, Marielle AX Russo ... Kimberly A Reynolds
    Deep mutational scanning of a synthetic allosteric chimera revealed that a sparse set of mutations on the protein surface improved regulation.

    Analysis of the PcrA-RNA polymerase complex reveals a helicase interaction motif and a role for PcrA/UvrD helicase in the suppression of R-loops

    Inigo Urrutia-Irazabal, James R Ault ... Mark S Dillingham
    RNA polymerase recruits the PcrA DNA helicase via a conserved interaction motif in order to remove R-loops and prevent conflicts with replication.

    The fluoride permeation pathway and anion recognition in Fluc family fluoride channels

    Benjamin C McIlwain, Roja Gundepudi ... Randy B Stockbridge
    In the extremely selective fluoride channels from the bacterial Fluc family, fluoride ions access the pore via two points, an electropositive vestibule and a triad of conserved residues involved in anion recognition.
