An evolutionary analysis of the reaction mechanisms of photosystem I reduction by cytochrome c(6) and plastocyanin - Rosa, Miguel A. de la; Navarro Carruesco, José Antonio; Díaz-Quintana, Antonio; Cerda, Berta de la; Molina-Heredia, Fernando P.; Balme, Alexis; Murdoch, Piedad del S.; Díaz-Moreno, Irene; Durán, Raúl V.; Hervás, Manuel
Photosystem I reduction by the soluble metalloproteins cytochrome c6 and plastocyanin, which are alternatively synthesized by some photosynthetic organisms depending on the relative availability of copper and iron, has been investigated in cyanobacteria, green algae and plants. The reaction mechanism is classified in three different types on the basis of the affinity of the membrane complex towards its electron donor protein. The role of electrostatic interactions in forming an intermediate transient complex, as well as the structural and functional similarities of cytochrome c6 and plastocyanin are analysed from an evolutionary point of view. The proposal made is that the heme...
