    摘要： Disclosed is a screening method which can select a substance having an influence on the binding between thioredoxin and MIF. The screening method is characterized in that a test substance capable of enhancing the binding between a polypeptide belonging to the thioredoxin family and a macrophage migration inhibitory factor is selected through the steps of mixing at least one binding substance selected from the substances (1) to (4) shown below with the test substance, allowing the binding substance to bind to the macrophage migration inhibitory factor, and confirming the binding between the binding substance and the macrophage migration inhibitory factor: (1) a polypeptide belonging to the thioredoxin family; (2) a protein which comprises an amino acid sequence produced by deleting, substituting or adding one or several amino acid residues in an amino acid sequence for a polypeptide belonging to the thioredoxin family and has the same activity as that of a polypeptide belonging to the thioredoxin family; (3) a gene encoding the polypeptide (1); and (4) a gene encoding the protein (2).

    摘要： Methods of reducing cystine containing animal and plant proteins, and improving dough and baked goods' characteristics is provided which includes the steps of mixing dough ingredients with a thiol redox protein to form a dough and baking the dough to form a baked good. The method of the present invention preferably uses reduced thioredoxin with wheat flour which imparts a stronger dough and higher loaf volumes. Methods for reducing snake, bee and scorpion toxin proteins with a thiol redox (SH) agent and thereby inactivating the protein or detoxifying the protein in an individual are also provided. Protease inhibitors, including the, Kunitz and Bowman-Birk trypsin inhibitors of soybean, were also reduced by the NADP/thioredoxin system (NADPH, thioredoxin, and NADP-thioredoxin reductase) from either E. coli or wheat germ. When reduced by thioredoxin, the Kunitz and Bowman-Birk soybean trypsin inhibitors lose their ability to inhibit trypsin. Moreover, the reduced form of the inhibitors showed increased susceptibility to heat and proteolysis by either subtilisin or a protease preparation from germinating wheat seeds. The 2S albumin of castor seed endosperm was reduced by thioredoxin from either wheat germ or E. coli. Thioredoxin was reduced by either NADPH and NADP-thioredoxin reductase or dithiothreitol. Analyses showed that thioredoxin actively reduced the intramolecular disulfides of the 2S large subunit, but was ineffective in reducing the intermolecular disulfides that connect the large to the small subunit. A novel cystine containing protein that inhibits pullulanase was isolated. The protein was reduced by thioredoxin and upon reduction its inhibitory activity was destroyed or greatly reduced.
