Overview
Plastocyanin is an important copper-containing protein involved in photosynthesis by all higher plants and some algae namely by Enteromorpha prolifera. Plastocyanin extracted from this alga, was the first alga blue copper protein characterized by X-ray crystallography and one of the best characterized electron transfer protein of the photosynthetic apparatus. This protein was intensively studied between 1981 and 1994 because of these particular spectroscopic and electronic properties. The high resolution structural analysis by molecular replacement in 19891 provided an accurate description of the structure of this protein. Plastocyanin is an electron donor localized in the intern membrane of thylakoïd in chloroplast. This is a monomeric protein with a single polypeptide chain of 98 amino acids and one copper atom. The molecular weight of plastocyanin is around 10,500 Daltons.
