CC   -!- FUNCTION: Apoprotein for the two 4Fe-4S centers FA and FB of
CC       photosystem I (PSI); essential for photochemical activity. FB is
CC       the terminal electron acceptor of PSI, donating electrons to
CC       ferredoxin. The C-terminus interacts with PsaA/B/D and helps
CC       assemble the protein into the PSI complex. Required for binding of
CC       PsaD and PsaE to PSI. PSI is a plastocyanin-ferredoxin
CC       oxidoreductase, converting photonic excitation into a charge
CC       separation, which transfers an electron from the donor P700
CC       chlorophyll pair to the spectroscopically characterized acceptors
CC       A0, A1, FX, FA and FB in turn. {ECO:0000255|HAMAP-Rule:MF_01303}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=hnu + oxidized [2Fe-2S]-[ferredoxin] + reduced
CC         [plastocyanin] = oxidized [plastocyanin] + reduced [2Fe-2S]-
CC         [ferredoxin]; Xref=Rhea:RHEA:30407, Rhea:RHEA-COMP:10000,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01303};
CC       Note=Binds 2 [4Fe-4S] clusters. Cluster 2 is most probably the
CC       spectroscopically characterized electron acceptor FA and cluster 1
CC       is most probably FB. {ECO:0000255|HAMAP-Rule:MF_01303};
CC   -!- SUBUNIT: The eukaryotic PSI reaction center is composed of at
CC       least 11 subunits. {ECO:0000255|HAMAP-Rule:MF_01303}.
