On coupling factors of oxidative phosphorylation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1968
Abstract 1. The isolation of three ATPase preparations from beef-heart mitochondria is described. One of these (F 1 -X) is soluble, oligomycin insensitive, cold labile and has a high coupling activity. The second is insoluble, oligomycin sensitive, cold stable and without coupling activity.

Binding of adenine nucleotides to the purified 13S coupling factor of bacterial oxidative phosphorylation

Archives of Biochemistry and Biophysics, 1976
Abstract The 13S coupling factor of oxidative phosphorylation from Alcaligenes faecalis forms an unusually stable complex with ADP which can be isolated by simple gel filtration. Most preparations of enzyme exhibit an apparent binding ratio of 1 mol of ADP per mol of enzyme with a dissociation constant of approximately 15 μ m .

Coupling Factors in Oxidative Phosphorylation

1978
A classical approach to the study of the mechanism of multienzyme systems involves resolution of the constituent parts and reconstitution of the system from the purified components. Application of this approach to the study of the mechanism of oxidative phosphorylation was first initiated in David Green’s laboratory.

On the identity of photo- and oxidative phosphorylation coupling factors in Rhodopseudomonas capsulata

Archives of Biochemistry and Biophysics, 1973
Abstract The nonsulfur purple photosynthetic bacterium Rhodopseudomonas capsulata can obtain energy for growth either by anaerobic photophosphorylation or dark oxidative (aerobic) phosphorylation. Earlier evidence for the in vitro interchangeability of phosphorylation coupling factor preparations from dark (aerobically) grown and photosynthetically ...

Electrophoretic microheterogeneity and subunit composition of the 13S coupling factors of oxidative and photosynthetic phosphorylation

Biochemistry, 1975
Two electrophoretically distinguishable species of the 13S coupling factor of oxidative phosphorylation from Alcaligenes faecalis are detectable by standard polyacrylamide gel electrophoresis in the absence of urea, detergents, or any other protein-denaturing reagents.

Studies on the mechanism of oxidative phosphorylation IV. A factor for coupled oxidation in the electron transport particle

Biochimica et Biophysica Acta, 1960
A procedure is described for the separation of the electron transport particle, ETPH, into two components, one a non-phosphorylating ETPH, the other a soluble protein. From these in the presence of Mg++ the phosphorylating system can be re-constituted; the maximum P/O ratios are respectively 1.0 and 0.6 for DPNH and succinate as substrates.

Interaction between coupling factors of oxidative phosphorylation and submitochondrial particles

Biochemical and Biophysical Research Communications, 1969
Abstract Coupling factor F3 does not bind to submitochondrial particles (A particles) unless F1 is simultaneously present. The same seems to be true for X, a coupling factor isolated together with F1.
