J. 9:328-333(2011). CC -!- FUNCTION: PsaA and PsaB bind P700, the primary electron donor of CC photosystem I (PSI), as well as the electron acceptors A0, A1 and CC FX. PSI is a plastocyanin-ferredoxin oxidoreductase, converting CC photonic excitation into a charge separation, which transfers an CC electron from the donor P700 chlorophyll pair to the CC spectroscopically characterized acceptors A0, A1, FX, FA and FB in CC turn. Oxidized P700 is reduced on the lumenal side of the CC thylakoid membrane by plastocyanin. {ECO:0000256|HAMAP- CC Rule:MF_00458}. 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 Rhea:RHEA-COMP:10001, Rhea:RHEA-COMP:10039, Rhea:RHEA- CC COMP:10040, ChEBI:CHEBI:29036, ChEBI:CHEBI:30212, CC ChEBI:CHEBI:33737, ChEBI:CHEBI:33738, ChEBI:CHEBI:49552; CC EC=1.97.1.12; Evidence={ECO:0000256|HAMAP-Rule:MF_00458}; CC -!- COFACTOR: CC Note=P700 is a chlorophyll a/chlorophyll a' dimer, A0 is one or CC more chlorophyll a, A1 is one or both phylloquinones and FX is a CC shared 4Fe-4S iron-sulfur center. {ECO:0000256|HAMAP- CC Rule:MF_00458}; CC -!- SUBUNIT: The PsaA/B heterodimer binds the P700 chlorophyll special CC pair and subsequent electron acceptors. PSI consists of a core CC antenna complex that captures photons, and an electron transfer CC chain that converts photonic excitation into a charge separation. CC The eukaryotic PSI reaction center is composed of at least 11 CC subunits. {ECO:0000256|HAMAP-Rule:MF_00458}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane CC {ECO:0000256|HAMAP-Rule:MF_00458}; Multi-pass membrane protein CC {ECO:0000256|HAMAP-Rule:MF_00458}. CC -!- SIMILARITY: Belongs to the PsaA/PsaB family. {ECO:0000256|HAMAP- CC Rule:MF_00458}.
