== Function == | |||
[https://www.uniprot.org/uniprot/PSAA_THEVB PSAA_THEVB] 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.<ref>PMID:10066799</ref> <ref>PMID:10066800</ref> <ref>PMID:11418848</ref> <ref>PMID:8901876</ref> | |||
