Current models of the photosystem I reaction centre are reviewed. The polypeptide composition of the reaction centre is described and the genetic origin of the peptides is documented. The properties of the redox components bound to the complex are reviewed. The chemical identity of the components, their location in the complex and the kinetics of electron transfer are discussed. It is concluded that a linear electron transport chain remains the best description of the function of the complex, but that the function and identity of the component A 1 remains uncertain.
