Abstract:
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.
