CC   -!- FUNCTION: PsaD can form complexes with ferredoxin and ferredoxin-
CC       oxidoreductase in photosystem I (PS I) reaction center.
CC   -!- SUBUNIT: The G.violaceus PSI reaction center is composed of one copy
CC       each of PsaA,B,C,D,E,F,L,M and Z, and forms trimeric complexes.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane protein;
CC       Cytoplasmic side.
CC   -!- SIMILARITY: Belongs to the PsaD family. {ECO:0000305}.
