CC   -!- FUNCTION: PsaD can form complexes with ferredoxin and ferredoxin-
CC       oxidoreductase in photosystem I (PS I) reaction center. PSAD may encode
CC       the ferredoxin-docking protein. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Stromal side
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PsaD family. {ECO:0000305}.
