Claim:
1. A protein complex containing at least a protein having at least one peak in a region of (1,085±50 cm −1 ) and a region of (1,411±50 cm −1 ), respectively, in FT-IR, wherein the protein comprises a precipitated and cross-linked protein, wherein the protein complex has an activity in catalyzing an asymmetric oxidation reaction, which selectively gives one enantiomer of a substrate racemic alcohol, wherein the protein complex has an active domain of a redox reaction, wherein the substrate racemic alcohol is selected from secondary alcohols having a benzene or naphthalene skeleton; or secondary alcohols having an alkyl chain and having no benzene or naphthalene skeleton, wherein the protein complex has a group, which has been produced by the air oxidation of the —SH group of cysteine, wherein the —SH group of cysteine has been derived from a crude protein from a water-soluble moiety derived from a plant, and wherein the plant is selected from grains selected from the group consisting of buckwheat, amaranth, rice, wheat, barley, corn, oats, rye, foxtail millet, barnyard millet, millet, adlay, and sorghum, and beans selected from the group consisting of adsuki beans, kidney beans, green peas, green beans, and soy beans.
