== Function ==

[https://www.uniprot.org/uniprot/~~PSAA_CHLRE PSAA_CHLRE~~] ~~PsaA and PsaB bind P700, the primary electron donor of photosystem I~~ (~~PSI~~), as ~~well as the electron acceptors A0~~, A1 and ~~FX. 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. Oxidized P700~~ is reduced on the lumenal side of the thylakoid membrane by plastocyanin or cytochrome c6. Both potential cofactor branches in PSI seem to be active; however, electron transfer seems to proceed preferentially down the path including the phylloquinone bound by PsaA.

[https://www.uniprot.org/uniprot/Q75VY9_CHLRE Q75VY9_CHLRE] The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated.[RuleBase:RU363080]
