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. PetL is
CC       important for photoautotrophic growth as well as for electron transfer
CC       efficiency and stability of the cytochrome b6-f complex.
CC       {ECO:0000255|HAMAP-Rule:MF_00433}.
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:0000255|HAMAP-
CC       Rule:MF_00433}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_00433}; Single-pass membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_00433}.
CC   -!- RNA EDITING: Modified_positions=19 {ECO:0000269|PubMed:15240834};
CC   -!- SIMILARITY: Belongs to the PetL family. {ECO:0000255|HAMAP-
CC       Rule:MF_00433}.
