    Intramolecular domain dynamics regulate synaptic MAGUK protein interactions

    Nils Rademacher et al.
    Binding of ligands to PSD-95 PDZ domains induces a conformational change within the C-terminal domain module that enables differential binding to synaptic interactors.

    Stepwise activation mechanism of the scramblase nhTMEM16 revealed by cryo-EM

    Valeria Kalienkova et al.
    cryo-EM reveals the properties of distinct conformations occupied during activation of the lipid scramblase nhTMEM16 and provides new insights into its interactions with the lipid environment.

    Schnyder corneal dystrophy-associated UBIAD1 inhibits ER-associated degradation of HMG CoA reductase in mice

    Youngah Jo et al.
    UBIAD1 mediates a unique geranylgeranyl pyrophosphate-sensing mechanism that when disrupted, inhibits degradation of HMG CoA reductase and triggers overproduction of corneal cholesterol that characterizes the eye disease Schnyder Corneal Dystrophy.

    Regulating G protein-coupled receptors by topological inversion

    Bray Denard et al.
    Multiple biochemical assays show that the topology of CCR5 and possibly other GPCRs may be inverted by ceramide or other sphingolipids through the process of regulated alternative translocation.

    Structures in multiple conformations reveal distinct transition metal and proton pathways in an Nramp transporter

    Aaron T Bozzi et al.
    Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.

    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

    Optical manipulation of sphingolipid biosynthesis using photoswitchable ceramides

    Matthijs Kol et al.
    Photoswitchable ceramides containing an azobenzene photoswitch behave as light-controllable substrates for both sphingomyelin synthase and glucosylceramide synthase.

    Pyrophosphate modulates plant stress responses via SUMOylation

    M Görkem Patir-Nebioglu et al.
    In vivo inhibition of SUMO activating E1-enzymes by pyrophosphate reveals a mode of integrating metabolism and stress tolerance that is conserved across kingdoms.

    Structure of a bacterial ATP synthase

    Hui Guo et al.
    Construction of a first atomic model for an intact bacterial ATP synthase allows for a structural understanding of the roles of individual amino acids in the mechanism of ATP synthesis.
