    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.

    Crystal structures of virus-like photosystem I complexes from the mesophilic cyanobacterium Synechocystis PCC 6803

    Yuval Mazor, Daniel Nataf ... Nathan Nelson
    The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

    Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria

    Yingying Wang, Xi Chen ... Kirstin Gutekunst
    Synechocystis switches its redox pools under reducing photomixotrophic conditions from utilizing NAD(H)- to ferredoxin-dependent enzymes and thereby balances its metabolism in a trade-off between energy conservation and chemical driving forces.

    The structure of photosystem I from a high-light-tolerant cyanobacteria

    Zachary Dobson, Safa Ahad ... Yuval Mazor
    The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.

    Flavodiiron proteins 1–to-4 function in versatile combinations in O2 photoreduction in cyanobacteria

    Anita Santana-Sanchez, Daniel Solymosi ... Yagut Allahverdiyeva
    In vivo evidence is provided indicating that Flv2/Flv4, together with Flv1/Flv3, mediate O2 photoreduction downstream of PSI in a highly coordinated manner.

    Cyanobacteria use micro-optics to sense light direction

    Nils Schuergers, Tchern Lenn ... Annegret Wilde
    The cells of a cyanobacterium act as spherical micro-lenses, allowing the cell to see a light source and move towards it.
