    Chemical perturbation of an intrinsically disordered region of TFIID distinguishes two modes of transcription initiation

    Zhengjian Zhang et al.
    An inorganic tin oxochloride cluster specifically binds to an intrinsically disordered, histidine-rich, low complexity protein region and arrests de novo transcription initiation without affecting reinitiation.

    Time-resolved serial femtosecond crystallography reveals early structural changes in channelrhodopsin

    Kazumasa Oda et al.
    Time-resolved serial femtosecond crystallography revealed retinal kink and early changes in channelrhodopsin, which leads to the ion pore formation.

    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.

    Functional instability allows access to DNA in longer transcription Activator-Like effector (TALE) arrays

    Kathryn Geiger-Schuller et al.
    Single molecule DNA-binding trajectories and deterministic modeling analyses demonstrate a functional role for high energy partly folded states in Transcription Activator-Like Effectors that could improve future TALEN design.

    A fusion peptide in preS1 and the human protein disulfide isomerase ERp57 are involved in hepatitis B virus membrane fusion process

    Jimena Pérez-Vargas et al.
    The mechanism triggering HBV membrane fusion involves ERp57, a cellular protein disulfide isomerase, and ultimately leads to the exposition of a fusion peptide that was identified in the pre-S1 determinant.

    Optocontrol of glutamate receptor activity by single side-chain photoisomerization

    Viktoria Klippenstein et al.
    Introduction of single photoswitchable unnatural amino acid into a neuronal receptor provides reversible, rapid and robust control of its activity by light, representing an important contribution to the fast expanding field of optopharmacology.

    Mutational analysis to explore long-range allosteric couplings involved in a pentameric channel receptor pre-activation and activation

    Solène N Lefebvre et al.
    A pentameric channel-receptor was studied by combining allosteric mutations, electrophysiology, fluorescent reporters and normal mode analysis, to dissect the long-range allosteric couplings specifically involved in its pre-activation and activation.

    Coupled ion binding and structural transitions along the transport cycle of glutamate transporters

    Grégory Verdon et al.
    Crystal structures of an archaeal homologue of mammalian glutamate transporters in apo and ion-only bound outward- and inward-facing states reveal ion-coupled conformational changes supporting mechanisms of coupling, gating, and transport.

    Structure and dynamics underlying elementary ligand binding events in human pacemaking channels

    Marcel P Goldschen-Ohm et al.
    Single-molecule resolution of cAMP binding to the ligand binding domain of pacemaking channels in zero-mode waveguides reveals the dynamics of the distinct steps underlying both binding and isomerization of the binding domain.

    Structure and topology around the cleavage site regulate post-translational cleavage of the HIV-1 gp160 signal peptide

    Erik Lee Snapp et al.
    Signal-peptide cleavage of HIV-1 envelope glycoprotein is delayed because of alpha-helical structure covering the cleavage site, effecting early cleavage alters the folding pathway and resulting in localized misfolding and reduced viral fitness.
