NAD(P)H oxidation by hydrogen peroxide in Escherichia coli.
A protein fraction from Escherichia Coli soluble extracts contain a NAD(P)H:hydrogen peroxide oxidoreductase activity. This activity is compared to and found to be distinct from well-known E. Coli enzymes involved in the protection from peroxides: hydroperoxidase I (HPI) and its o-dianisidine peroxidase component and the alkyl hydroperoxide reductase.
