[[http://www.uniprot.org/uniprot/PSAB_PEA PSAB_PEA]] 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-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 (By similarity). [[http://www.uniprot.org/uniprot/PSAC_PEA PSAC_PEA]] 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-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 (By similarity).[HAMAP-Rule:MF_01303] [[http://www.uniprot.org/uniprot/PSAE1_ARATH PSAE1_ARATH]] Stabilizes the interaction between PsaC and the PSI core, assists the docking of the ferredoxin to PSI and interacts with ferredoxin-NADP oxidoreductase (By similarity). [[http://www.uniprot.org/uniprot/PSAH_SPIOL PSAH_SPIOL]] Possible role could be the docking of the LHC I antenna complex to the core complex. [[http://www.uniprot.org/uniprot/PSAJ_SPIOL PSAJ_SPIOL]] May help in the organization of the PsaE and PsaF subunits. [[http://www.uniprot.org/uniprot/PSAD_SPIOL PSAD_SPIOL]] PsaD can form complexes with ferredoxin and ferredoxin-oxidoreductase in photosystem I (PS I) reaction center. PSAD may encode the ferredoxin-docking protein. [[http://www.uniprot.org/uniprot/CB24_PEA CB24_PEA]] The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated.<ref>PMID:2174365</ref>  May channel protons produced in the catalytic Mn center of water oxidation into the thylakoid lumen.<ref>PMID:2174365</ref>  [[http://www.uniprot.org/uniprot/CAB6_ARATH CAB6_ARATH]] The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated. [[http://www.uniprot.org/uniprot/PSAF_SPIOL PSAF_SPIOL]] Probably participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI. [[http://www.uniprot.org/uniprot/PSAI_PEA PSAI_PEA]] May help in the organization of the PsaL subunit. [[http://www.uniprot.org/uniprot/PSAA_PEA PSAA_PEA]] 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-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.
