|
||
| Function: | |
Involved in the binding and/or turnover of quinones at the Q(B) site 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. {ECO:0000269|PubMed:12518057, ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:23426624}. |
|

| Cofactor: | |
Note=PSII binds multiple chlorophylls, carotenoids and specific lipids. {ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260, ECO:0000269|PubMed:23426624}; |
| Subunit: | |
Cyanobacterial 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, Ycf12, 3 peripheral proteins PsbO, PsbU, PsbV and a large number of cofactors. It forms dimeric complexes. {ECO:0000269|PubMed:12518057, ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260, ECO:0000269|PubMed:23426624}. |
| Subcellular location: | |
Cellular thylakoid membrane {ECO:0000269|PubMed:12518057, ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260, ECO:0000269|PubMed:23426624}; Single-pass membrane protein {ECO:0000269|PubMed:12518057, ECO:0000269|PubMed:19433803, ECO:0000269|PubMed:21499260, ECO:0000269|PubMed:23426624}. |
| Similarity: | |
Belongs to the PsbX family. Type 1 subfamily. {ECO:0000305}. |
