Cofactor Recycling Using a Thermostable NADH Oxidase
From the standpoint of enzymatic organic synthesis, NADH oxidase (NOX) will be a key enzyme that plays an essential role in the cofactor regeneration of NAD+ dependent enzymatic reactions. For example, enzymatic enantioselective oxidations of racemic secondary alcohols (Geueke et al., 2003; Riebel et al., 2003; Hummel & Riebel, 1996) and amino acids (Hummel et al., 2003a) have been reported as ...
متن کاملPurification and characterization of NADH oxidase from Serpulina (Treponema) hyodysenteriae.
NADH oxidase (EC 1.6.99.3) was purified from cell lysates of Serpulina (Treponema) hyodysenteriae B204 by differential ultracentrifugation, ammonium sulfate precipitation, and chromatography on anion-exchange, dye-ligand-affinity, and size-exclusion columns. Purified NADH oxidase had a specific activity 119-fold higher than that of cell lysates and migrated as a single band during denaturing ge...
متن کاملNADH oxidase activity of mitochondrial apoptosis-inducing factor.
Apoptosis-inducing factor (AIF) is a mitochondrial flavoprotein, which translocates to the nucleus during apoptosis and causes chromatin condensation and large scale DNA fragmentation. Here we report the biochemical characterization of AIF's redox activity. Natural AIF purified from mitochondria and recombinant AIF purified from bacteria (AIFDelta1-120) exhibit NADH oxidase activity, whereas su...
متن کاملExpression of NADH/NADPH oxidase p22phox in human coronary arteries.
BACKGROUND NADH/NADPH oxidase is an important source of superoxide in the vasculature. Recently, we found that polymorphism of the gene p22phox, a critical component of this oxidase, is associated with a risk of coronary artery disease. The aim of this study was to investigate the localization of p22phox in human coronary arteries and to examine its difference in expression between nonatheroscl...
متن کاملContribution of NADH oxidase to aerobic metabolism of Streptococcus pyogenes.
An understanding of how the heme-deficient gram-positive bacterium Streptococcus pyogenes establishes infections in O(2)-rich environments requires careful analysis of the gene products important in aerobic metabolism. NADH oxidase (NOXase) is a unique flavoprotein of S. pyogenes and other lactic acid bacteria which directly catalyzes the four-electron reduction of O(2) to H(2)O. To elucidate a...
