The homology between cytochrome B-5, hemoglobin, and myoglobin.

Functional analogues of cytochrome c oxidase, myoglobin, and hemoglobin.

The majority of modern organisms, including many prokaryotes, are aerobes;1 that is, they use molecular oxygen as the terminal electron acceptor for energy generation. Although nearly every redox gradient in nature appears to be utilized by one organism or another,2-4 aerobic metabolism predominates, in large part due to the highly exergonic nature of the four-electron, four-proton (4e/4H+) red...

Hemoglobin and Myoglobin

The tertiary structure of myoglobin is that of a typical water soluble globular protein. Its secondary structure is unusual in that it contains a very high proportion (75%) of α-helical secondary structure. A myoglobin polypeptide is comprised of 8 separate right handed α-helices, designated A through H, that are connected by short non helical regions. Amino acid R-groups packed into the interi...

Spectroscopic determination of cytochrome c oxidase content in tissues containing myoglobin or hemoglobin.

A simple spectroscopic method for determining the cytochrome c oxidase, cytochrome a, a3, content in tissue and mitochondria samples independent of myoglobin or blood contamination is described. Using tissue homogenates solubilized in Triton X-100, this assay relies on the selective reduction of mitochondrial cytochromes by the action of potassium cyanide. Monitoring the optical absorbance of t...
