General annotation (Comments)

Function

One of the two reaction center proteins of photosystem II (PSII), D2 is needed for assembly of a stable PSII complex By similarity. HAMAP MF_01383

Catalytic activity

2 H2O + 2 plastoquinone + 4 light = O2 + 2 plastoquinol. HAMAP MF_01383

Cofactor

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

Subunit structure

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.

Subcellular location

Cellular thylakoid membrane; Multi-pass membrane protein By similarity HAMAP MF_01383.

Miscellaneous

The peripheral chlorophyll-a D2 molecule has been identified as the spectroscopic species ChlzD2 By similarity. HAMAP MF_01383

Sequence similarities

Belongs to the reaction center pufL/M/psbA/D family.
