WebMutations in more than 20 genes have been found to cause cytochrome c oxidase deficiency. Most genes are found in DNA in the cell's nucleus (nuclear DNA).However, some genes are found in DNA in specialized cell structures called mitochondria.This type of DNA is known as mitochondrial DNA (mtDNA). Most cases of cytochrome c oxidase … WebJun 29, 2024 · Cytochrome c (Cc) is well-known as an electron carrier at mitochondria but can also catalyze peroxidase-like reactions. Although the reported catalytic abilities are low, the role of Cc in transforming environmental toxicants requires additional studies. We employed cardiolipin vesicles to stimulate the enzymatic activity of Cc and tested the …

Certain cytochrome complexes, such as cytochromes a and a 3 (called cytochrome aa 3) and cytochromes b and o (called cytochrome bo) are called cytochrome oxidases, because they can transfer electrons directly to O 2 to form H 2 O.
The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. Cytochromes are, thus, capable of performing electron transfer reactions and catalysis by reduction or oxidation of their heme iron. The cellular location of cytochromes depends on their function. They can be found as globular proteins
