    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz et al.
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    Kinetic mechanism of coupled binding in sodium-aspartate symporter GltPh

    SeCheol Oh, Olga Boudker
    Sodium ions control the rates of both substrate binding and dissociation of an archaeal homologue of glutamate transporters in a manner that minimizes binding intermediates and maximizes transport efficiency.

    AFF4 binding to Tat-P-TEFb indirectly stimulates TAR recognition of super elongation complexes at the HIV promoter

    Ursula Schulze-Gahmen et al.
    AFF4 increases the combined selectivity of HIV Tat and TAR for super elongation complexes 330-fold over P-TEFb alone.

    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.

    Dynamics of venom composition across a complex life cycle

    Yaara Y Columbus-Shenkar et al.
    Different developmental stages of a venomous animal (e.g. Nematostella vectensis) with a complex life cycle produce vastly different venoms that can serve in different antagonistic interactions with other species.

    DNA polymerase V activity is autoregulated by a novel intrinsic DNA-dependent ATPase

    Aysen L Erdem et al.
    DNA synthesis by DNA polymerase V is regulated by an intrinsic DNA-dependent ATPase activity which has not been observed for any other polymerase.

    Structure of the SAS-6 cartwheel hub from Leishmania major

    Mark van Breugel et al.
    The X-ray structure of the SAS-6 cartwheel hub from Leishmania major demonstrates that SAS-6 can be sufficient to determine centriolar cartwheel symmetry.

    Phosphorylation-mediated PTEN conformational closure and deactivation revealed with protein semisynthesis

    David Bolduc et al.
    C-terminal phosphorylation of the lipid phosphatase PTEN drives a reduction in membrane affinity and leads to a more compact conformation that involves a C2 domain-tail interaction.

    Conformational dynamics in TRPV1 channels reported by an encoded coumarin amino acid

    Ximena Steinberg et al.
    Single-molecule measurement of conformational dynamics using a genetically encoded fluorescent probe suggests that the selectivity filter region of TRPV1 channels undergoes dynamic motion during agonist activation.
