  • Cyanobacteria evolved carbon-concentration mechanisms to enhance the efficiency of photosynthetic CO2 fixation, but the molecular principles have remained unknown. Here authors use cryo-EM to reveal how modular adaptations enabled the photosynthetic complex I from the cyanobacterium Thermosynechococcus elongatus to concentrate CO2.

  • Photosynthetic Complex I (PS-CI) is proposed to couple ferredoxin oxidation and plastoquinone reduction to proton pumping across thylakoid membranes. Here the authors determine the reduction potentials of the iron-sulphur clusters of PS-CI and thus the bioenergetics of the electron transfer relay.
