CC -!- FUNCTION: PsaD can form complexes with ferredoxin and ferredoxin-
CC oxidoreductase in photosystem I (PS I) reaction center.
CC -!- SUBUNIT: PS I from Synechocystis PCC 6803 contains seven different
CC polypeptides. The polypeptide corresponding to subunit II from higher
CC plants is missing.
CC -!- INTERACTION:
CC P19569; P27320: petF; NbExp=3; IntAct=EBI-595298, EBI-863421;
CC -!- SIMILARITY: Belongs to the PsaD family. {ECO:0000305}.
