5-Deazariboflavin
CAS:5-Deazariboflavin is a proton carrier that is found in the mitochondrial cytochrome b. It has been shown to bind covalently to the protein, forming 5-deazariboflavin-protein adducts. These adducts are formed by reacting with amines and other amino acids present in the protein. In vitro studies have shown that 5-deazariboflavin inhibits Mycobacterium avium growth and acid production by binding to the enzyme pyruvate kinase, which is involved in glycolysis. 5-Deazariboflavin can also be used as an indicator of pH because it is reduced at low pH levels and oxidized at high pH levels. The second order rate constant for this reaction can be determined using kinetic data, such as absorbance or fluorescence properties.
