The stoichiometry of photophosphorylation

Biochemical and Biophysical Research Communications, 1965
Abstract Using chloroplasts from three different plant species in the presence of four different buffer systems we found that the P 2e ratio was consistently above 1.0 if the pH was between 8.4 and 9.4. At pH 8.9 the ratio was usually above 1.25 and indeed no single determination of the ratio fell below 1.1 at this pH unless Tris-HCl was ...

Inhibition of photophosphorylation by ATP and the role of magnesium in photophosphorylation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1976
ATP and pyrophosphate at high concentration (greater than 1 mM) inhibited photophosphorylation of isolated spinach chloroplasts in the normal salt medium and did not cause stimulation of electron transport. The inhibition of photophosphorylation by ATP or pyrophosphate was shown to be abolished by the addition of excess MgCl2, ADP and phosphate. It has

The effects of plastocyanin on photophosphorylation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1969
Abstract 1. 1. A simplified procedure for the large-scale isolation and purification of plastocyanin from spinach chloroplasts is reported. After electrophoresis on polyacrylamide gel, a pure protein was obtained as judged by analytical gel electrophoresis and by the fact that it contained no arginine. 2. 2.

Inhibitors and uncouplers of photophosphorylation

Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1965
Abstract 1. 1. A survey of the effect of inhibitors and uncouplers of oxidative phosphorylation on chloroplast photophosphorylation led to the discovery of new inhibitors and uncouplers of this process. 2. 2. n-Butyl-3,5-diiodo-4-hydroxybenzoate was found to inhibit both electron transport and the coupled ATP formation.

On the origin of photophosphorylation

Journal of Theoretical Biology, 1977
Abstract A model based on quinol phosphates is proposed for the origin of photophosphorylation. This model is divided into three time periods. In the early period, when the primitive earth was under reducing conditions, quinol phosphates were produced through quinol radical intermediates formed by the activation of hydroquinones with ultraviolet ...
