CC   -!- FUNCTION: PsaD can form complexes with ferredoxin and ferredoxin-
CC       oxidoreductase in photosystem I (PS I) reaction center.
CC   -!- SUBUNIT: The cyanobacterial PSI reaction center is composed of one copy
CC       each of PsaA,B,C,D,E,F,I,J,K,L,M and X, and forms dimeric and
CC       tetrameric complexes. {ECO:0000269|PubMed:24550276}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane
CC       {ECO:0000269|PubMed:24550276}; Peripheral membrane protein; Cytoplasmic
CC       side.
CC   -!- SIMILARITY: Belongs to the PsaD family. {ECO:0000305}.
