  • VARIANT NITRILE HYDRATASES, MICROBIA WHICH EXPRESS SAME, AND USE IN AMIDE SYNTHESIS
    Publication number: 20250297293
    Abstract: The present invention relates to a variant nitrile hydratase which is engineered to comprise greater activity and/or stability, nucleic acids encoding said nitrile hydratase, and microbia engineered to express said novel nitrile hydratase. Additionally the invention relates to the use of this nitrile hydratase and microbia which express said nitrile hydratase as a biocatalyst, particularly in methods for producing an amide compound from a nitrile compound, preferably for use in converting acrylonitrile to acrylamide.
