Chemical Engineering of Enzymes: Altered Catalytic Activity, Predictable Selectivity and Exceptional Stability of the Semisynthetic Peroxidase Seleno-Subtilisin

2  H). As a consequence, the former proteolytic enzyme gained peroxidase activity and catalyzed the selective reduction of hydroperoxides. Due to the identical binding sites of the semisynthetic peroxidase and the protease, the substrate selectivity of seleno-subtilisin was predictable in view of the well-known selectivity of subtilisin.
