Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

One of the two reaction center proteins of photosystem II (PSII), D2 is needed for assembly of a stable PSII complex By similarity.UniRule annotation

Catalytic activityi

2 H2O + 2 plastoquinone + 4 light = O2 + 2 plastoquinol.UniRule annotation

Cofactori

The psbA/B heterodimer shares a non-heme iron and each subunit also binds two chlorophylls and pheophytin By similarity.

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.
