Hydrogen peroxide-forming NADH oxidase and DNA encoding the same

摘要

It is an object of the present invention to provide DNA encoding novel NADH oxidase from a microorganism belonging to the genus Brevibacterium having excellent pH stability and thermostability. The present invention relates to DNA encoding NADH oxidase from a microorganism belonging to the genus Brevibacterium that is the following (a) or (b): (a) NADH oxidase comprising the amino acid sequence of SEQ ID NO: 18; or (b) NADH oxidase comprising an amino acid sequence derived from the amino acid sequence of SEQ ID NO: 18 by deletion, substitution, or addition of 1 or more amino acid(s) and having NADH oxidase activity.
