Comments [?]

Function 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 H(2)O, generating O(2) 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.
Subunit PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, numerous small proteins, at least 3 peripheral proteins of the oxygen-evolving complex and a large number of cofactors. It forms dimeric complexes.
case <OG:Chloroplast>
Subcellular location Plastid, chloroplast thylakoid membrane; Single-pass membrane protein.
else case <OC:Gloeobacter>
Subcellular location Cell inner membrane; Single-pass membrane protein.
else
Subcellular location Cellular thylakoid membrane; Single-pass membrane protein.
end case
case <FTTag:phospho>
Ptm Phosphorylation is a light-dependent reaction catalyzed by a membrane-bound kinase; phosphorylation occurs on Thr residue(s) in the N-terminus of the protein.
end case
Similarity Belongs to the PsbH family.
