| FUNCTION | Loosely associated component of the core of photosystem II (PSII). PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating a proton gradient subsequently used for ATP formation. |
| 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. |
| else | |
| SUBUNIT | PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbY, PsbZ, Psb30/Ycf12, at least 3 peripheral proteins of the oxygen- evolving complex and a large number of cofactors. It forms dimeric complexes. |
| end case | |
| case not <OG:Chloroplast> | |
| SUBCELLULAR LOCATION | Cellular thylakoid membrane; Single-pass membrane protein. |
| else case <OG:Chloroplast> | |
| SUBCELLULAR LOCATION | Plastid, chloroplast thylakoid membrane; Single- pass membrane protein. |
| end case | |
| SIMILARITY | Belongs to the PsbY family. |
