ID 1.11.1.24 DE thioredoxin-dependent peroxiredoxin. AN thioredoxin peroxidase. CA [thioredoxin]-dithiol + a hydroperoxide = [thioredoxin]-disulfide + CA an alcohol + H2O. CC -!- Peroxiredoxins (Prxs) are a ubiquitous family of antioxidant CC proteins. CC -!- They can be divided into three classes: typical 2-Cys, atypical 2-Cys CC and 1-Cys peroxiredoxins. CC -!- The peroxidase reaction comprises two steps centered around a redox- CC active cysteine called the peroxidatic cysteine. CC -!- All three peroxiredoxin classes have the first step in common, CC in which the peroxidatic cysteine attacks the peroxide substrate and CC is oxidized to S-hydroxycysteine (a sulfenic acid). CC -!- The second step of the peroxidase reaction, the regeneration of CC cysteine from S-hydroxycysteine, distinguishes the three CC peroxiredoxin classes. CC -!- For typical 2-Cys Prxs, in the second step, the peroxidatic CC S-hydroxycysteine from one subunit is attacked by the 'resolving' CC cysteine located in the C-terminus of the second subunit, to form an CC intersubunit disulfide bond, which is then reduced by one of several CC cell-specific thiol-containing reductants completing the catalytic CC cycle. CC -!- In the atypical 2-Cys Prxs, both the peroxidatic cysteine and its CC resolving cysteine are in the same polypeptide, so their reaction CC forms an intrachain disulfide bond. CC -!- The 1-Cys Prxs conserve only the peroxidatic cysteine, so its CC regeneration involves direct interaction with a reductant molecule. CC -!- Thioredoxin-dependent peroxiredoxins are the most common. CC -!- They have been reported from archaea, bacteria, fungi, plants, CC and animals. CC -!- Formerly EC 1.11.1.15.
