WebMar 23, 2006 · Thioredoxins are small ubiquitous proteins with a highly conserved active site sequence [ (Cys-Gly-Pro-Cys) (Holmgren 1985, 1995a; Martin 1995 )]. These proteins share a common 3-D architecture known as the thioredoxin motif, consisting of four α-helices and five β-sheets (Eklund et al. 1991; Holmgren 1995b; Martin 1995; Capitani et al. … Thioredoxins are small disulfide-containing redox proteins that have been found in all the kingdoms of living organisms. Thioredoxin serves as a general protein disulfide oxidoreductase. It interacts with a broad range of proteins by a redox mechanism based on reversible oxidation of 2 cysteine thiol groups to a disulfide, accompanied by the transfer of 2 electrons and 2 protons. The net result is the covalent interconversion of a disulfide and a dithiol.
