Depletion reveals role of bicarbonate in the photosynthetic electron transport chain of Limnospira maxima
Efficient photosynthetic light reactions require tight balancing of electrons and protons. In photosystem II, bicarbonate is coordinated to a non-heme iron positioned between the acceptor-side plastoquinones QA and QB, modulating electron transfer. The hypercarbonate-requiring filamentous cyanobacte...
