Enzyme, enzyme electrode, biosensor, bioreactor, and biofuel cell

Abstract

An enzyme electrode that includes: an electrode base material; a first catalyst layer on the electrode base material, the first catalyst layer including an enzyme (a1) capable of catalyzing an oxidation-reduction reaction of a redox couple of NAD(P)H and NAD(P) and capable of direct electron exchange between the enzyme (a1) and the electrode base material accompanying the oxidation-reduction reaction; and a second catalyst layer on the first catalyst layer, the second catalyst layer including an NAD(P)H or NAD(P) dependent oxidoreductase (b) and NAD(P)H and/or NAD(P).

Dependencies are inferred from the claim text.
