Members of this protein family are the PsaK of the photosystem I reaction center. Photosystems I and II occur together in the same sets of organisms. Photosystem I uses light energy to transfer electrons from plastocyanin to ferredoxin, while photosystem II uses light energy to split water and releases molecular oxygen [Energy metabolism, Photosynthesis].

Members of this protein family are the PsaK of the photosystem I reaction center. Photosystems I and II occur together in the same sets of organisms. Photosystem I uses light energy to transfer electrons from plastocyanin to ferredoxin, while photosystem II uses light energy to split water and releases molecular oxygen.

Photosystem II (PSII) has a P680 reaction centre containing chlorophyll 'a' that uses light energy to carry out the oxidation (splitting) of water molecules, and to produce ATP via a proton pump. Photosystem I (PSI) has a P700 reaction centre containing chlorophyll that takes the electron and associated hydrogen donated from PSII to reduce NADP+ to NADPH. Both ATP and NADPH are subsequently used in the light-independent reactions to convert carbon dioxide to glucose using the hydrogen atom extracted from water by PSII, releasing oxygen as a by-product. Photosystem I (PSI) [] is an integral membrane protein complex that uses light energy to mediate electron transfer from plastocyanin to ferredoxin. It is found in the chloroplasts of plants and cyanobacteria. PSI is composed of at least 14 different subunits, two of which, PSI-G (gene psaG) and PSI-K (gene psaK), are small hydrophobic proteins of about 7 to 9 Kd and evolutionary related []. Both seem to contain two transmembrane regions. Cyanobacteria contain only PSI-K.; GO: 0015979 photosynthesis, 0009522 photosystem I, 0016020 membrane; PDB: 2O01_G 2WSF_G 2WSE_G 2WSC_G 3PCQ_K 1JB0_K.
