General description
Isobutyronitrile (IBN) is an aliphatic nitrile. It is widely used as a solvent for electrochemical analyses. IBN can be prepared from amino acids, via anaerobic degradation. It undergoes oxidative dehydrogenation in the presence of an iron phosphate catalyst to afford methacrylonitrile, acetone, carbon oxides and traces of cyanic acid.

Nitrile hydratase (NHase) is a non-heme iron or non-corrin cobalt enzyme having two post-translationally modified ligand residues, cysteine-sulfinic acid (alphaCys112-SO(2)H) and -sulfenic acid (alphaCys114-SOH). We studied the interaction between Fe-type NHase and isobutyronitrile (iso-BN) which had been reported as a
