Structure of Photosystem I Acclimated to Far-red Light

Loading... Status: waiting for Mol* initialization Structural highlights 6pnj is a 30 chain structure with sequence from Fischerella thermalis PCC 7521. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Electron Microscopy, Resolution 3.19Å Ligands: BCR, CA, CLA, F6C, LHG, LMG, LMT, PQN Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function G6FME9_9CYAN 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.[HAMAP-Rule:MF_00458] PsaA and psaB bind P700, the primary electron donor of photosystem I (PSI), as well as the electron acceptors A0, A1 and FX.[RuleBase:RU003775] See Also Photosystem I 3D structures
