In oxygen-evolving photosynthesis, the conversion of
light energy into electrochemical potential requires
two photosystems working in close collaboration. In
higher plants, these photosystems are integrated into
the thylakoid membrane of the chloroplast, a
cytoplasmic organelle (Fig. 1). The two photosystems
­ photosystem I and photosystem II ­ are wired
electrically, in series, therefore the electrons flowing
through one photosystem must travel at the same
rate as those flowing through the other1,2. In all green
