Journal of Biological Chemistry, 1970 Abstract When a purified bovine heart cytochrome c oxidase was polarographically assayed by a method involving initial contact of the enzyme with Tween 80, very high turnover numbers were observed at low enzyme concentrations, e.g. 5 to 10 mµm cytochrome a3.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells
FEBS Letters, EarlyView.Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Protonmotive cooperativity in cytochrome c oxidase
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2004 Cooperative linkage of solute binding at separate binding sites in allosteric proteins is an important functional attribute of soluble and membrane bound hemoproteins. Analysis of proton/electron coupling at the four redox centers, i.e. Cu(A), heme a, heme a(3) and Cu(B), in the purified bovine cytochrome c oxidase in the unliganded, CO-liganded and CN-

Mitochondrial fatty acid oxidation is stimulated by red light irradiation
FEBS Letters, EarlyView.Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Upregulation of Mitochondrial Content in Cytochrome c Oxidase Deficient Fibroblasts. [PDF]
PLoS ONE, 2016 Cytochrome-c-oxidase (COX) deficiency is a frequent cause of mitochondrial disease and is associated with a wide spectrum of clinical phenotypes. We studied mitochondrial function and biogenesis in fibroblasts derived from the Cohen (CDs) rat, an animal ...
