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. |
| case <OC:Cyanobacteriota> | |
| SUBUNIT | PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Psb30/Ycf12, peripheral proteins PsbO, CyanoQ (PsbQ), PsbU, PsbV and a large number of cofactors. It forms dimeric complexes. |

| end case | |
| case <OG:Chloroplast> | |
| SUBCELLULAR LOCATION | Plastid, chloroplast thylakoid membrane; Single- pass membrane protein. |
| else case <OC:Gloeobacter> | |

| 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. |
