Claim:
1. A process for producing an optically active alcohol comprising reacting a racemic alcohol as a substrate with a protein complex comprising a crystallized precipitated and cross-linked protein, to thereby selectively obtain one enantiomer of the racemic alcohol, wherein the crystallized precipitated and cross-linked protein has 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 precipitated and cross-linked protein has an active domain of a redox reaction, and the 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 —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.
