    Redox-controlled reorganization and flavin strain within the ribonucleotide reductase R2b–NrdI complex monitored by serial femtosecond crystallography

    Juliane John, Oskar Aurelius ... Martin Högbom
    The flavoprotein NrdI in class Ib ribonucleotide reductase controls superoxide generation and metal site oxidation by tuning the redox properties of its flavin cofactor via steric strain induced by the formation of the R2b–NrdI protein complex.

    Single-molecule analysis of the entire perfringolysin O pore formation pathway

    Conall McGuinness, James C Walsh ... Till Böcking
    Arc-shaped PFO oligomers consisting of at least four subunits can insert into the membrane in a kinetically controlled process opening a transmembrane pore, whereby post-insertion growth may ultimately lead to formation of a complete ring.

    Structural model of microtubule dynamics inhibition by kinesin-4 from the crystal structure of KLP-12 –tubulin complex

    Shinya Taguchi, Juri Nakano ... Ryo Nitta
    Structural, functional, and genetic analyses reveal how kinesin-4 motor KLP-12 precisely modulates the curvature of the microtubule plus-end to inhibit the microtubule dynamics for achieving the proper length control of axons.

    Proton-transporting heliorhodopsins from marine giant viruses

    Shoko Hososhima, Ritsu Mizutori ... Hideki Kandori
    A viral heliorhodopsin from Emiliania huxleyi virus 202 (V2HeR3) is a light-activated proton transporter, which has the potential to depolarize the host cells by light, possibly to overcome the host defense mechanisms or to prevent superinfection.

    In situ single particle classification reveals distinct 60S maturation intermediates in cells

    Bronwyn A Lucas, Kexin Zhang ... Nikolaus Grigorieff
    Comparing the relative similarity of cellular molecules to alternate templates allows classification of related complexes in the cell using fewer particles than needed for 3D classification and is more practicable for low abundance complexes.

    Impact of energy limitations on function and resilience in long-wavelength Photosystem II

    Stefania Viola, William Roseby ... A William Rutherford
    Comparisons of enzyme efficiency and electron transfer show that, to oxidize water using lower energy light, the two types of far-red photosystem II have adopted opposite trade-offs between efficiency of light use and resilience to light damage.

    Photosynthesis: Surviving on low-energy light comes at a price

    Elisabet Romero
    Two species of photosynthetic cyanobacteria can thrive in far-red light but they either become less resilient to photodamage or less energy efficient.

    Double NPY motifs at the N-terminus of the yeast t-SNARE Sso2 synergistically bind Sec3 to promote membrane fusion

    Maximilian Peer, Hua Yuan ... Gang Dong
    A novel dual-site binding between the yeast t-SNARE Sso2 and Sec3 (a component of the exocyst tethering complex) facilitates the fusion of secretory vesicles with the plasma membrane.
