摘要: NAD(P)H oxidase is disclosed having the following enzymological properties:(1) ActionIt oxidizes NADH or NADPH in the presence of oxygen to form NAD or NAD and hydrogen peroxide.NAD(P)H+H.sup.+ +O.sub.2 .fwdarw.NAD(P).sup.+ +H.sub.2 O.sub.2(2) Substrate specificityIt acts upon NADH and NADPH.(3) Optimum pHIts optimum pH lies in the range of about 9 to 10. Also disclosed is a process for producing the NAD(P)H oxidase and a method for determining the quantity of substrate or enzyme activity in a sample solution by utilizing a reaction system forming NADH or NADPH.
