Resolution of cytochrome oxidase into two component complexes.

چکیده
Cytochrome c oxidase (ferrocytochrome c: oxygen oxidoreductase, EC 1.9.3.1) has been resolved into a pair of complexes of unequal molecular weight. The larger complex (electron transfer complex) contains exclusively the oxidation-reduction proteins characteristic of cytochrome oxidase; the smaller complex (ion transfer complex) shows exclusively the capability for cation-dependent induction of the fluorescence of 8-anilino-1-naphthalenesulfonic acid--a capability demonstrable in preparations of cytochrome oxidase. The duplex nature of cytochrome oxidase has important implications for the mechanism of energy coupling.

Projection structure of the cytochrome bo ubiquinol oxidase from Escherichia coli at 6 A resolution.
The haem-copper cytochrome oxidases are terminal catalysts of the respiratory chains in aerobic organisms. These integral membrane protein complexes catalyse the reduction of molecular oxygen to water and utilize the free energy of this reaction to generate a transmembrane proton gradient. Quinol oxidase complexes such as the Escherichia coli cytochrome bo belong to this superfamily. To elucida...

The identification of the efficiency of some mtDNA genes of Mus musculus species complex (house mouse) for biosystematics research was studied in this approach. Recent studies have made use of different mitochondrial genes including NADH dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, D-loop region and whole mtDNA genome to study the house mouse species. Usage of each of these...

1. The membrane-bound succinoxidase of Escherichia coli was fractionated with deoxycholate into three soluble components, viz. succinate dehydrogenase.cytochrome b1 complex, cytochrome oxidase complex, and a factor identified as a phospholipid-containing component. 2. The dehydrogenase and cytochrome oxidase complexes were partially purified by filtration on Amicon membranes, Sepharose 4B chrom...
متن کاملRcf1 mediates cytochrome oxidase assembly and respirasome formation, revealing heterogeneity of the enzyme complex.
The terminal enzyme of the mitochondrial respiratory chain, cytochrome oxidase, transfers electrons to molecular oxygen, generating water. Within the inner mitochondrial membrane, cytochrome oxidase assembles into supercomplexes, together with other respiratory chain complexes, forming so-called respirasomes. Little is known about how these higher oligomeric structures are attained. Here we rep...

The EPR spectra of the NO complexes of frozen solutions of ascorbic acid-reduced cytochrome oxidase (nitrite reductase) purified from Pseudomonas aeruginosa, of its heme d1-depleted form, and of heme d1 in solutions containing various nitrogenous bases are quite similar to each other as well as to several heme (iron protoporphyrin IX)-containing proteins. The NO complexes of heme d1 (an iron-ch...
