A novel electrocatalyst made of an oxidase having high electron transfer efficiency and an enzymatic electrode using the same are provided. The electrocatalyst is made of CueO. The enzymatic electrode comprises a carbonaceous porous body and an electrocatalyst made of CueO supported on the surface of the carbonaceous porous body. CueO is preferably CueO from. The carbonaceous porous body constituting the enzymatic electrode is preferably carbonaceous gel. Also, the enzymatic electrode may further comprise a mediator which facilitates transfer of electron between the carbonaceous porous body and said CueO.

Electrocatalyst and enzymatic electrode

Modified CueO having excellent enzymatic activity and a composition for dyeing keratin fiber which contains the enzyme. A recombinant protein having an enzymatic activity for oxidizing p-phenylenediamine, the protein is obtained by removing from CueO at least one member selected from the group consisting of helix 5, helix 6, and helix 7; and the composition for dyeing keratin fiber containing the recombinant protein and an oxidation dye.
