Open AccessStructural dynamics in the water and proton channels of photosystem II during the S2 to S3 transition
Light-driven oxidation of water to molecular oxygen is catalyzed by the oxygen-evolving complex (OEC) in Photosystem II (PS II). This multi-electron, multi-proton catalysis requires the transport of two water ...

Open AccessRoom temperature XFEL crystallography reveals asymmetry in the vicinity of the two phylloquinones in photosystem I
Photosystem I (PS I) has a symmetric structure with two highly similar branches of pigments at the center that are involved in electron transfer, but shows very different efficiency along the two branches. We ...

Structures of the intermediates of Kok’s photosynthetic water oxidation clock
Inspired by the period-four oscillation in flash-induced oxygen evolution of photosystem II discovered by Joliot in 1969, Kok performed additional experiments and proposed a five-state kinetic model for photos...

Open AccessNew insights into the mechanism of substrates trafficking in Glyoxylate/Hydroxypyruvate reductases
Glyoxylate accumulation within cells is highly toxic. In humans, it is associated with hyperoxaluria type 2 (PH2) leading to renal failure. The glyoxylate content within cells is regulated by the NADPH/NADH de...
