Protein
Photosystem II reaction center protein I
Gene
psbI
Organism
Triticum aestivum (Wheat)
Status
Functioni
One of the components of the core complex of photosystem II (PSII), required for its stability and/or assembly. PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H2O, generating O2 and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation.UniRule annotation
