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

CC   -!- COFACTOR:

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 is
CC       most probably FB. {ECO:0000255|HAMAP-Rule:MF_01303};
CC   -!- SUBUNIT: The eukaryotic PSI reaction center is composed of at least 11
CC       subunits. {ECO:0000255|HAMAP-Rule:MF_01303}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000255|HAMAP-Rule:MF_01303}; Peripheral membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01303}; Stromal side {ECO:0000255|HAMAP-
CC       Rule:MF_01303}.
CC   -!- CAUTION: A stretch of the chloroplast genome is duplicated within
CC       chromosomes 6 and 7 resulting in the duplication of the gene. The
CC       expression of these duplicated genes has not been demonstrated.
CC       {ECO:0000305}.
