    The protein

    Catalyzed reaction/ biological activity

  • release of ammonia from reactive enamine/imine intermediates of the pyridoxal 5'-phosphate-dependent threonine dehydratase ([protein|D0CF32BF81AA1DC7BBBC3E9B667A54F97260DF3F|IlvA]) [pubmed|22094463]
  • 2-iminobutanoate + H2O = 2-oxobutanoate + NH3 [pubmed|22094463]
