cytochrome oxidase

In many ways it looks like one big cytochrome oxidase blob!

The produced oxygen can then be reduced to water by action of the enzyme cytochrome oxidase.

For example, E. coli does not have a cytochrome oxidase or a bc complex.

In Leigh's disease, there may be an abnormality or deficiency of cytochrome oxidase.

Similarly, there are columns in the cortex that have high levels of the protein cytochrome oxidase.

These are called cytochrome oxidase "blobs" because of their scattered blob-like appearance.

Cyanmethemoglobin is formed and the cytochrome oxidase enzyme is restored.

The monophyly of this genus was not supported by a molecular study using the cytochrome oxidase I gene.

Additionally, myoglobin and mitochondrial cytochrome oxidase are thought to be adversely affected.

What identifies these zones is that they contain a high concentration of the enzyme, cytochrome oxidase (CO).

It is negative for the following tests: nitrate respiration, fermentative growth, catalase, and cytochrome oxidase.

Carbon monoxide also binds to other molecules such as myoglobin and mitochondrial cytochrome oxidase.

In 1946 he concluded that cytochrome oxidase and other enzymes responsible for the respiratory chain were isolated to the mitchondria.

The main product, sulphide, is toxic to cells and impairs cellular metabolism through inhibition of cytochrome oxidase.

According to cytochrome oxidase I sequence studies, its closest relationship is with the genus Amphichaeta of the same subfamily.

In mitochondria the terminal membrane complex (Complex IV) is cytochrome oxidase.

When applied to the newly discovered cytochrome oxidase blobs in the visual cortex of primates the correlational approach is quite revealing.

Additionally, practically every combination of having or not having orientation, dominance, and cytochrome oxidase columns has been observed in one species or another.

They were first identified in 1979 by Margaret Wong-Riley when she used a cytochrome oxidase stain, from which they get their name.

The bacterium readily ferments and oxidizes glucose, is catalase, and cytochrome oxidase positive.

The nitrites oxidize hemoglobin to methemoglobin, which competes with cytochrome oxidase for the cyanide ion.

Oxidase-positive bacteria possess cytochrome oxidase or indophenol oxidase (an iron-containing hemoprotein).

Cyanide is a potent inhibitor of respiration, acting on mitochondrial cytochrome oxidase and hence blocking electron transport.

As mentioned above, hydrogen sulfide binds to cytochrome oxidase and thereby prevents oxygen from binding, which leads to the dramatic slowdown of metabolism.

Azide inhibits cytochrome oxidase by binding irreversibly to the heme cofactor in a process similar to the action of carbon monoxide.
