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=1 {ECO:0000250}, 27 {ECO:0000250}, 34
CC {ECO:0000250}; Note=The initiator methionine is created by RNA editing.
CC The stop codon at position 34 is created by RNA editing. {ECO:0000250};
CC -!- SIMILARITY: Belongs to the PetL family. {ECO:0000255|HAMAP-
CC Rule:MF_00433}.
CC -!- CAUTION: The transcript is probably edited at the RNA level as has been
CC shown for P.thunbergii, P.armandii, P.mugo, Larix kaempferi and Abies
CC homolepis (see PubMed:15240834). {ECO:0000305}.
