    Functioni

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