== Function ==
 +
[https://www.uniprot.org/uniprot/PSAC_SYNP2 PSAC_SYNP2] Apoprotein for the two 4Fe-4S centers FA and FB of photosystem I (PSI); essential for photochemical activity. FB is the terminal electron acceptor of PSI, donating electrons to ferredoxin. The C-terminus interacts with PsaA/B/D and helps assemble the protein into the PSI complex. Required for binding of PsaD and PsaE to PSI. PSI is a plastocyanin/cytochrome c6-ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized acceptors A0, A1, FX, FA and FB in turn.[HAMAP-Rule:MF_01303] Mutant proteins with a 3Fe-4S center are not observed bound to PSI in vitro, and are probably not able to do so in vivo.[HAMAP-Rule:MF_01303]
