Interactioni

Subunit structurei

The psbA/B heterodimer binds the P680 chlorophylls and subsequent electron acceptors. PSII consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. PSII forms dimeric complexes By similarity.
