CC   -!- FUNCTION: One of the components of the core complex of photosystem II
CC       (PSII), required for its stability and/or assembly. PSII is a light-
CC       driven water:plastoquinone oxidoreductase that uses light energy to
CC       abstract electrons from H(2)O, generating O(2) and a proton gradient
CC       subsequently used for ATP formation. It consists of a core antenna
CC       complex that captures photons, and an electron transfer chain that
CC       converts photonic excitation into a charge separation.
case <OC:Cyanobacteriota>
CC   -!- SUBUNIT: PSII is composed of 1 copy each of membrane proteins PsbA,
CC       PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT,
CC       PsbX, PsbY, PsbZ, Psb30/Ycf12, peripheral proteins PsbO, CyanoQ (PsbQ),
CC       PsbU, PsbV and a large number of cofactors. It forms dimeric complexes.

case <OG:Chloroplast>
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Single-
CC       pass membrane protein.

CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Single-pass membrane
CC       protein.
else
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Single-pass membrane
CC       protein.
end case
case <FTTag:phospho>
CC   -!- PTM: Phosphorylation is a light-dependent reaction catalyzed by a
CC       membrane-bound kinase; phosphorylation occurs on Thr residue(s) in the
CC       N-terminus of the protein.
end case
CC   -!- SIMILARITY: Belongs to the PsbH family.
