Definitions for "Thioredoxin"
An enzyme that causes the formation and breaking of disulphide bridges in other proteins. Thioredoxin from E. coli also binds to DNA polymerase of bacteriophage T7 and thereby increase processivity of the polymerase.
Thioredoxins are proteins that act as antioxidants by facilitating the reduction of other proteins by cysteine thiol-disulfide exchange. Thioredoxins are found in nearly all known organisms and are essential for life in mammals.
