Abstract

The chemical identity of the primary electron acceptor of photosystem I has been an active area of investigation for several years. Early proposals were that a chlorophyll molecule might be involved as a primary acceptor for photosystem I (Kamen 1961, 1963). The discovery and characterization of a soluble chloroplast iron-sulfur protein, ferredoxin, by Tagawa and Arnon(1962) led to the proposal that this protein functions as the primary acceptor. This view was based largely on the half-reduction potential (E m) of −420 mV for soluble ferredoxin at pH 7.0, a value equivalent to that of the hydrogen electrode.
