Cytochrome oxidase, with the CAS number 9001-16-5, is a crucial enzyme found in the electron transport chain of mitochondria, playing a vital role in cellular respiration. This enzyme catalyzes the reduction of oxygen to water, utilizing electrons derived from reduced cytochromes. It is a complex protein composed of multiple subunits and contains heme groups, which are essential for its function. Cytochrome oxidase is integral to ATP production, as it facilitates the establishment of a proton gradient across the mitochondrial membrane, ultimately driving ATP synthesis through oxidative phosphorylation. The enzyme exhibits a high affinity for oxygen and is sensitive to various inhibitors, such as cyanide and carbon monoxide, which can disrupt its activity. Its activity can be influenced by factors such as pH, temperature, and the presence of specific cofactors. Due to its critical role in energy metabolism, cytochrome oxidase is of significant interest in studies related to bioenergetics, aging, and various metabolic disorders.
