In oxygenic photosynthesis, the two protein–pigment complexes photosystem I and photosystem II are involved in the light-driven charge separation across the thylakoid membrane, which results in the oxidation of water to O2 and in the reduction of NADP+ to NADPH. In addition to a photosynthetic reaction centre, each of these photosystems contains a core antenna system. The crystal structure of photosystem I reveals the spatial organization of protein subunits and cofactors.
