| Function | Involved in the binding and/or turnover of quinones at the Q(B) site of Photosystem II. |
| Subunit | 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. |
