UniProt Comments

Function: This is one of the two reaction center proteins of photosystem II

By similarity. HAMAP-Rule MF_01379

Catalytic activity: 2 H2O + 2 plastoquinone + 4 light = O2 + 2 plastoquinol. HAMAP-Rule 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: Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein

By similarity HAMAP-Rule MF_01379.

Miscellaneous: Herbicides such as atrazine, BNT, diuron or ioxynil bind to Q(B) and block electron transport

By similarity. HAMAP-Rule MF_01379

Sequence similarities: Belongs to the reaction center PufL/M/PsbA/D family.
