Cytochrome Oxidase Activity.

Purified mitochondria were used to calculate a decrease in OD at 550 nm (0.625-5 μg/reaction). In Blank, no change in the OD was observed. Rate is calculated by subtracting the initial OD reading from the final OD, t1 and t2 represents linear rate of reaction.

产品详情

Cytochrome C Oxidase Activity Assay Kit (ab239711) is simple, fast and high-throughput adaptable. This assay kit can be used for purified mitochondria or tissue extracts containing mitochondria. The kit provides for the fast and simple measurement of Cytochrome c oxidase activity on a 96-well plate format. The activity of the enzyme is determined colorimetrically by following the oxidation of reduced Cytochrome c as an absorbance decrease at 550 nm.

补充信息

This supplementary information is collated from multiple sources and compiled automatically.

Complex IV also known as cytochrome c oxidase is an important component of the electron transport chain in mitochondria. This enzyme complex has significant mass approximately 204 kDa and operates primarily in the inner mitochondrial membrane. It catalyzes the transfer of electrons from cytochrome c to oxygen facilitating ATP generation. Complex IV is ubiquitously expressed in all tissues with higher expression in organs with high energy demands like heart and skeletal muscle. This enzyme is composed of multiple subunits encoded by both mitochondrial and nuclear DNA.
Biological function summary

Cytochrome c oxidase plays a critical role in cellular respiration. It forms part of the larger enzyme complex which also includes Complex I II and III. These complexes work together to create a proton gradient across the inner mitochondrial membrane essential for ATP synthesis via oxidative phosphorylation. This enzyme's activity is measured through assays like the cytochrome c oxidase assay which evaluates its function in various tissues. These assays help researchers understand how effectively electrons are being transferred and protons are driven across the membrane.

Pathways

Complex IV is integral to the oxidative phosphorylation pathway and the broader mitochondrial respiratory chain. It interacts closely with cytochrome c a small heme protein that shuttles electrons between Complex III (cytochrome c reductase) and Complex IV. Through these interactions the proton gradient is established enabling ATP synthase to convert chemical energy into usable cell energy. This process significantly impacts cellular metabolism and energy production influencing how efficiently cells function.

Complex IV dysfunction is associated with mitochondrial diseases and certain neurodegenerative disorders. For instance defects in cytochrome c oxidase lead to conditions like Leigh syndrome a severe neurological disorder. Also studies show that disruptions in the electron transport chain involving Complex IV relate closely to Alzheimer's disease. Alterations in proteins like cytochrome c which work in tandem with Complex IV can exacerbate these conditions highlighting the importance of this target in understanding and potentially treating these diseases.

靶点信息

Component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation. The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Electrons originating from reduced cytochrome c in the intermembrane space (IMS) are transferred via the dinuclear copper A center (CU(A)) of subunit 2 and heme A of subunit 1 to the active site in subunit 1, a binuclear center (BNC) formed by heme A3 and copper B (CU(B)). The BNC reduces molecular oxygen to 2 water molecules using 4 electrons from cytochrome c in the IMS and 4 protons from the mitochondrial matrix.
