Abstract
A novel reductase which is an enzyme that can catalyze the reduction of methionine sulfoxide resides in proteins is described. The enzyme has been found in E. coli, Euglena gracilis, Tetrahymena pyriformis, Hela cells, rat tissue and spinach. The enzyme has an estimated molecular weight of about 18,000-20,000. It can be used to restore biological activity to proteins inactivated by oxidation of methionine residues.
