Catalytic Mechanism And Maturation Of The Metalloenzyme Nitrile Hydratase, Natalie I. Gumataotao

Dissertations

Nitrile hydratases are metalloenzymes that catalyze the hydration of nitriles to their corresponding amides in a specific manner at ambient pressures and temperatures at neutral pH. Traditional industrial methods require high temperature and pressure, extreme pH, and heavy metals. NHases are used as biocatalysts in the large scale industrial production of amide precursors to textiles, animal feedstock, and polymers. Notably, NHase is used in the production of ~100,000 tons of acrylamide annually by the Mitsubishi Corporation.

Despite being used extensively in industry, questions remain about NHase. The catalytic mechanism is not defined. Understanding the way in which the nitrile is …
