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.
CC {ECO:0000256|ARBA:ARBA00003402}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=hnu + oxidized [2Fe-2S]-[ferredoxin] + reduced [plastocyanin]
