additional information the purified recombinant enzyme PlRIR exhibits relatively high catalytic efficiency towards 2,3,3-trimethylindolenine. A panel of 3H-indoles and 3H-indole iodides are reduced by PlRIR to yield the corresponding products with high enantioselectivity of 66-98% enantiomeric excess. In addition, enzyme PlRIR also possesses good activities toward other types of imines such as pyrroline, tetrahydropyridine, and dihydroisoquinoline, indicating a reasonably broad substrate acceptance Paenibacillus lactis ?
