NADPH dehydrogenase

NADPH dehydrogenase (EC 1.6.99.6) catalyses the univalent reduction of O2 to O2 according to the reaction  [Pg.88]

NADPH dehydrogenase has also been shown to catalyse the divalent reduction of O2 to H2O2 under certain experimental conditions (Green and Wu 1986, Green and Pratt 1987). The value for [Pg.88]

NADPH dehydrogenase is an enzyme system, which apparently consists of multiple components localised in the plasmalemma, in specific granules, and in the cytosol of phagocytes. A number of components has been suggested to be involved in the redox chain of NADPH dehydrogenase, including flavine adenine dinucleotide (FAD), quinones, and a phagocyte-specific cytochrome referred as cytochrome fc.245. [Pg.89]

There is substantial experimental evidence for the assumption that cytochrome fc.245 is the terminal redox component of NADPH dehydrogenase. Cyo-tochrome. 245 has been identified in various types of phagocytes including neutrophils, eosinophils, HL-60 cells, and mononuclear cells (Segal et al. 1981). [Pg.89]

This result suggests that oxygen is utilized by moiecules such as NADPH-dehydrogenase, or consumed in processes such as photorespiration. It is noteworthy that the maximum value of hydrogen evolution is 10 times larger than that of oxygen evolution. [Pg.335]

Successful resolution and characterization of the components of steroid 11 p-hydroxylase have been achieved by us (26, 27, 60) and by Omura et al. (44,47) through the discovery of the flavoprotein, (NADPH-dehydrogenase), and a ferredoxin-like non-heme iron protein (adreno-... [Pg.3]
