THE MECHANISM OF PHOTOPHOSPHORYLATION IN CHLOROPLASTS
Abstract
The investigation performed concentrated around four aspects: (1) UV irradiation of chloroplasts: The inhibitory effects of ultraviolet irradiation on photophosphorylation and the Hill Reaction was investigated. The mechanism of the inactivation was related to the chloroplastic components which were destroyed by the treatment. (2) Photophosphorylation as a tool for the synthesis of specifically labelled nucleotides. (3) Light activated adenosine triphosphatase. (4) Reversible uncoupling of photophosphorylation. Treating chloroplasts with ethylenediaminetetraacetate brought about complete uncoupling of the photophosphorylating system. Partial recoupling could be affected by incubation of a three component system consisting of: the treated chloroplasts, the components released by the treatment (containing a small amount of protein), and a metal ion.
