OX NCBI_TaxID=2731864 {ECO:0000313|EMBL:QJQ75593.1}; RN [1] {ECO:0000313|EMBL:QJQ75593.1} RP NUCLEOTIDE SEQUENCE. RA Duan L., Chen H.-F., Wen J.; RL Submitted (FEB-2020) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Component of the cytochrome b6-f complex, which mediates CC electron transfer between photosystem II (PSII) and photosystem I CC (PSI), cyclic electron flow around PSI, and state transitions. PetG is CC required for either the stability or assembly of the cytochrome b6-f CC complex. {ECO:0000256|HAMAP-Rule:MF_00432}. CC -!- SUBUNIT: The 4 large subunits of the cytochrome b6-f complex are CC cytochrome b6, subunit IV (17 kDa polypeptide, PetD), cytochrome f and CC the Rieske protein, while the 4 small subunits are PetG, PetL, PetM and CC PetN. The complex functions as a dimer. {ECO:0000256|HAMAP- CC Rule:MF_00432}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004167}; Single- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004167}. Plastid, CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_00432}; CC Single-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00432}. CC -!- SIMILARITY: Belongs to the PetG family. {ECO:0000256|HAMAP- CC Rule:MF_00432}.
