CC   -!- FUNCTION: May play a key role in regulating the relative amounts of
CC       cyclic and non-cyclic electron flow to meet the demands of the plant
CC       for ATP and reducing power. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + NADP(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NADPH + 2
CC         oxidized [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:20125, Rhea:RHEA-

CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC   -!- PATHWAY: Energy metabolism; photosynthesis. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma {ECO:0000250}.
CC       Plastid, chloroplast thylakoid membrane {ECO:0000250}; Peripheral
CC       membrane protein {ECO:0000250}; Stromal side {ECO:0000250}. Note=In the
CC       vicinity of the photosystem I in the non-stacked and fringe portion of
CC       the membrane. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ferredoxin--NADP reductase type 1 family.
CC       {ECO:0000305}.
