Insertion of selenocysteine (Sec) into protein scaffolds provides an opportunity for designing enzymes with improved and unusual catalytic properties. The use of a common thioredoxin fold with a high affinity for glutathione in glutaredoxin (Grx) and glutathione peroxidase (GPx) suggests a possibility of engineering Grx into GPx and vice versa.
