OX NCBI_TaxID=2711; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=cv. Osbeck var. Ridge Pineapple; RX PubMed=17010212; DOI=10.1186/1471-2229-6-21; RA Bausher M.G., Singh N.D., Lee S.-B., Jansen R.K., Daniell H.; RT "The complete chloroplast genome sequence of Citrus sinensis (L.) RT Osbeck var 'Ridge Pineapple': organization and phylogenetic RT relationships to other angiosperms."; RL BMC Plant Biol. 6:21-21(2006). 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. CC PetG is required for either the stability or assembly of the CC cytochrome b6-f complex (By similarity). CC -!- SUBUNIT: The 4 large subunits of the cytochrome b6-f complex are CC cytochrome b6, subunit IV (17 kDa polypeptide, petD), cytochrome f CC and the Rieske protein, while the 4 small subunits are petG, petL, CC petM and petN. The complex functions as a dimer (By similarity). CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; CC Single-pass membrane protein (By similarity). CC -!- SIMILARITY: Belongs to the petG family.
