| Function: | |
This b-type cytochrome is tightly associated with the reaction center of photosystem II (PSII). 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. {ECO:0000255|HAMAP-Rule:MF_00643}. |

| Cofactor: | |
Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence={ECO:0000255|HAMAP-Rule:MF_00643}; Note=With its partner (PsbE) binds heme. PSII binds additional chlorophylls, carotenoids and specific lipids. {ECO:0000255|HAMAP- Rule:MF_00643}; |
| Subunit: | |
Heterodimer of an alpha subunit and a beta 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, Ycf12, at least 3 peripheral proteins of the oxygen-evolving complex and a large number of cofactors. It forms dimeric complexes. {ECO:0000255|HAMAP-Rule:MF_00643}. |
| Subcellular location: | |
Plastid, chloroplast thylakoid membrane {ECO:0000255|HAMAP-Rule:MF_00643}; Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00643}. |
| Similarity: | |
Belongs to the PsbE/PsbF family. {ECO:0000255|HAMAP- Rule:MF_00643}. |
