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 ...
