    Abstract: An object of the present invention is to obtain a protein monomer useful as a raw material for medicines industrially and economically in high yield and high purity. In the method for purifying a protein of the present invention, a protein solution containing a protein monomer and a protein aggregate is passed through a column holding a porous rigid polymeric self-supporting structure to which a hydrophobic group is immobilized, and then recovering the protein monomer in a flow-through mode.

    Abstract: Provided is a method of removing a protein aggregate which can obtain a useful protein monomer in a high yield and a high purity as a raw material of a pharmaceutical product or the like. The method of removing a protein aggregate includes: a step of making the monomer of a protein and the aggregate of proteins adsorb to the column by making a solution containing a monomer of a protein and an aggregate of proteins pass through a column containing a hard porous polymer self-supporting structure to which a strong cation exchange group is fixed; and a step of making a mobile phase consisting of a mixed solution of a buffer solution and an ionic buffer solution pass through the column to which the monomer of a protein and the aggregate of proteins are adsorbed, to selectively elute the monomer of a protein.

    Abstract: A method of manufacturing 1,4-butanediol, using a microbe and/or a culture thereof, by an enzyme reaction system that uses acyl-CoA reductase, via 3-hydroxybutyryl-CoA, crotonyl-CoA and 4-hydroxybutyryl CoA in this order, wherein the reactivity of the acyl-CoA reductase to 4-hydroxybutyryl CoA is greater than or equal to 0.05 times of the reactivity of the acyl-CoA reductase to 3-hydroxybutyryl-CoA.
