plastocyanin : ウィキペディア英語版 | plastocyanin
Plastocyanin is a copper-containing protein involved in electron-transfer. The protein is monomeric, with a molecular weight around 10,500 Daltons, and 99 amino acids in most vascular plants. It is a member of the plastocyanin family of copper-binding proteins. ==Function== In photosynthesis, plastocyanin functions as an electron transfer agent between cytochrome f of the cytochrome ''b''6''f'' complex from photosystem II and P700+ from photosystem I. Cytochrome ''b''6''f'' complex and P700+ are both membrane-bound proteins with exposed residues on the lumen-side of the thylakoid membrane of chloroplasts. Cytochrome f acts as an electron donor while P700+ accepts electrons from reduced plastocyanin.
