Cytochrome b is commonly used as a region of mitochondrial DNA for determining phylogenetic relationships between organisms, due to its sequence variability. It is considered to be most useful in determining relationships within families and genera. Comparative studies involving cytochrome b have resulted in new classification schemes and have ...
Location of the MT-CYB gene in the human mitochondrial genome (coral box).. Cytochrome b is a protein that in humans is encoded by the MT-CYB gene. [5] Its gene product is a subunit of the respiratory chain protein ubiquinol–cytochrome c reductase (UQCR, complex III or cytochrome bc 1 complex), which consists of the products of one mitochondrially encoded gene, MT-CYB (mitochondrial ...
Complex IV contains a cytochrome a/a3-domain that transfers electrons and catalyzes the reaction of oxygen to water. Photosystem II, the first protein complex in the light-dependent reactions of oxygenic photosynthesis, contains a cytochrome b subunit. Cyclooxygenase 2, an enzyme involved in inflammation, is a cytochrome b protein.
The specialized protein cytochrome b5 is a class B cytochrome with a high and low potential heme b attached to the central iron on the protein. [4] The cytochrome b class is especially unique because it is attached to proteins within the inner mitochondrial membrane instead of on the outer portion, and this particular class has high sequence ...
Cytochrome b-c1 complex subunit 1, mitochondrial is a protein that in humans is encoded by the UQCRC1 gene. [5] [6]Its gene product is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase (UQCR, Complex III or Cytochrome bc1 complex), which consists of the products of one mitochondrially encoded gene, MTCYTB (mitochondrial cytochrome b) and ten nuclear genes: UQCRC1 ...

Cytochrome b is a heterodimer of two glycoproteins, gp91phox (also known as the heavy or β chain) and p22phox (the light or α chain).The heavy and light chains are closely associated in phagocytic cells, but while the expression of gp91phox is restricted to these cells, p22phox has been detected in many other cell types [1] and is able to function as a component of NAD(P)H oxidases.

Cytochrome b-c1 complex subunit 6, mitochondrial is a protein that in humans is encoded by the UQCRH gene. [4] [5]Its gene product is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase (UQCR, Complex III or Cytochrome bc1 complex; E.C. 1.10.2.2), which consists of the products of one mitochondrially encoded gene, MTCYTB (mitochondrial cytochrome b) and ten nuclear ...
