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 FX. CC PSI 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. Oxidized P700 is reduced on CC the lumenal side of the thylakoid membrane by plastocyanin. CC {ECO:0000256|ARBA:ARBA00003162, ECO:0000256|HAMAP-Rule:MF_00458}. CC -!- CATALYTIC ACTIVITY: CC Reaction=hnu + oxidized [2Fe-2S]-[ferredoxin] + reduced [plastocyanin] CC = oxidized [plastocyanin] + reduced [2Fe-2S]-[ferredoxin]; CC Xref=Rhea:RHEA:30407, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001, CC Rhea:RHEA-COMP:10039, Rhea:RHEA-COMP:10040, ChEBI:CHEBI:29036, CC ChEBI:CHEBI:30212, ChEBI:CHEBI:33737, ChEBI:CHEBI:33738, CC ChEBI:CHEBI:49552; EC=1.97.1.12; CC Evidence={ECO:0000256|ARBA:ARBA00000994, ECO:0000256|HAMAP- CC Rule:MF_00458}; CC -!- COFACTOR: CC Note=P700 is a chlorophyll a/chlorophyll a' dimer, A0 is one or more CC chlorophyll a, A1 is one or both phylloquinones and FX is a shared 4Fe- CC 4S iron-sulfur center. {ECO:0000256|HAMAP-Rule:MF_00458}; CC -!- SUBUNIT: The PsaA/B heterodimer binds the P700 chlorophyll special pair CC and subsequent electron acceptors. PSI consists of a core antenna CC complex that captures photons, and an electron transfer chain that CC converts photonic excitation into a charge separation. The eukaryotic CC PSI reaction center is composed of at least 11 subunits. CC {ECO:0000256|ARBA:ARBA00026002, ECO:0000256|HAMAP-Rule:MF_00458}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Plastid, CC chloroplast thylakoid membrane {ECO:0000256|HAMAP-Rule:MF_00458}; CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00458}. CC -!- SIMILARITY: Belongs to the PsaA/PsaB family.
