Abstract

Abstract A factor from spinach chloroplasts stimulates both photoreduction of ferricyanide and photophosphorylation where assayed using isolated chloroplasts. This factor consists of a low molecular weight chromophore attached by non-covalent bonds to a protein. Spectral and chemical evidence suggests that the factor is a direct link in the photosynthetic electron transport chain and does not act as an uncoupling agent nor in pseudo-cyclic phosphorylation.
