    Structural basis for an unprecedented enzymatic alkylation in cylindrocyclophane biosynthesis

    Nathaniel R Braffman, Terry B Ruskoski ... Emily P Balskus
    The X-ray crystal structure of the unusual carbon–carbon bond-forming biosynthetic enzyme CylK reveals a unique biochemical strategy for selective alkyl halide activation and substitution.

    A saturation-mutagenesis analysis of the interplay between stability and activation in Ras

    Frank Hidalgo, Laura M Nocka ... John Kuriyan
    Deep mutagenesis experiments demonstrate that while cancer-causing mutations in Ras selectively alter regulatory interactions with GTPase-activating proteins, Ras is also activated by many mutations that decrease protein stability.

    Identification of electroporation sites in the complex lipid organization of the plasma membrane

    Lea Rems, Xinru Tang ... Lucie Delemotte
    Advanced data analysis of molecular dynamics simulations of complex lipid membranes provides a quantitative and predictive model of the molecular features that control electroporation.

    How clustered protocadherin binding specificity is tuned for neuronal self-/nonself-recognition

    Kerry Marie Goodman, Phinikoula S Katsamba ... Barry Honig
    Surface plasmon resonance studies reveal that clustered protocadherins have precisely tuned trans homophilic binding interactions and promiscuous but variable cis interactions, consistent with the requirement of forming error-free linear molecular zippers used by mammalian neurons to distinguish self from nonself.

    Cryo-EM structures reveal high-resolution mechanism of a DNA polymerase sliding clamp loader

    Christl Gaubitz, Xingchen Liu ... Brian A Kelch
    Cryo-EM structures of the eukaryotic clamp loader illustrate the large conformational changes that the clamp loader ATPase undergoes to open the circular sliding clamp and place it onto primer–template DNA.

    Structure and ion-release mechanism of PIB-4-type ATPases

    Christina Grønberg, Qiaoxia Hu ... Pontus Gourdon
    A biochemical approach unveils the overall shape of a subclass of heavy-metal transporting pumps, thereby shedding light on principle molecular determinants linked to the transport mechanism of these elusive machines, information that is critical well beyond basic science.

    Conformational decoupling in acid-sensing ion channels uncovers mechanism and stoichiometry of PcTx1-mediated inhibition

    Stephanie A Heusser, Christian B Borg ... Stephan A Pless
    A peptide toxin with therapeutic potential in stroke and pain induces multiple long-lasting conformational changes in acid-sensing ion channels and affects how the channels respond to endogenous ligands.

    Creation of photocyclic vertebrate rhodopsin by single amino acid substitution

    Kazumi Sakai, Yoshinori Shichida ... Takahiro Yamashita
    Through a single mutation at position 188, vertebrate rhodopsin acquires the ability to recover the dark state from the active state by a thermal reaction and by a photoreaction.

    Mg2+-dependent conformational equilibria in CorA and an integrated view on transport regulation

    Nicolai Tidemand Johansen, Marta Bonaccorsi ... Lise Arleth
    The Mg2+-channel CorA explores a wide conformational landscape of non-conducting states irrespective of bound Mg2+, but only in abscence of Mg2+, conducting states become accessible due to increased backbone dynamics.

    An empirical energy landscape reveals mechanism of proteasome in polypeptide translocation

    Rui Fang, Jason Hon ... Ying Lu
    Empirical energy landscape allows simulating the structural dynamics of the proteasomal ATPase complex, which yields predictions that are widely consistent with experimental observations and reveals the functional mechanism of the proteasome in substrate degradation.
