General annotation (Comments)

Function

This is one of the two reaction center proteins of photosystem II By similarity. HAMAP MF_01379

Catalytic activity

2 H2O + 2 plastoquinone + 4 light = O2 + 2 plastoquinol. HAMAP MF_01379

Cofactor

The psbA/B heterodimer binds P680, the primary electron donor of PSII. It shares a non-heme iron and each subunit binds additional chlorophylls and pheophytin. PsbA provides most of the ligands for the Mn-cluster of the oxygen-evolving complex 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

Plastidchloroplast thylakoid membrane; Multi-pass membrane protein By similarity HAMAP MF_01379.

Miscellaneous

Herbicides such as atrazine, BNT, diuron or ioxynil bind to Q(B) and block electron transport By similarity. HAMAP MF_01379

Sequence similarities

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

Caution

A stretch of the chloroplast genome is duplicated within chromosomes 4 and 8 resulting in the duplication of the gene. The expression of these duplicated genes (Os04g0236400 and Os08g0455300) has not been demonstrated.
