Chemical identity and properties
Thioredoxins
Thioredoxin is a small dithiol protein and specific reductant for major allergenic proteins present in foods from animal and plant products. It is a 12-kD oxidoreductase enzyme encoded by TXN and TXN2 genes that contains a dithiol-disulfide active site. It plays an essential role as an antioxidant in neutralizing food allergens and redox signalling. Allergens containing disulfide bonds are inactivated when reduced by thioredoxin. — DrugBank
