Engineered Surface-Immobilized Enzyme that Retains High Levels of Catalytic Activity in Air.

In the absence of aqueous buffer, most enzymes retain little or no activity; however, "water-free" enzymes would have many diverse applications. Here, we describe the chemically precise immobilization of an enzyme on an engineered surface designed to support catalytic activity in air at ambient humidity. Covalent immobilization of haloalkane dehalogenase on… CONTINUE READING
