Nitrile hydratases (NHase) catalyze the hydration of nitriles to the corresponding amides. We report on the heterologous expression of various nitrile hydratases. Some of these enzymes have been investigated by others and us before, but sixteen target proteins represent novel

Tissue-specific induction of cytochrome P-450s (CYP) followed by increased in situ bioactivation may contribute to chemical-induced site-specific toxicity. In rats, methacrylonitrile (MAN) is metabolized by cytochrome P-450 2E1 (CYP2E1) to acetone, which is eliminated along with parent MAN in breath.
