IUBMB Comments
phenylacetonitrile,[reduced NADPH-hemoprotein reductase]:oxygen oxidoreductase [(R)-mandelonitrile-forming]
The enzyme has been characterized from the cyanogenic millipede Chamberlinius hualienensis. Unlike plant enzymes that can catalyse this reaction (EC 1.14.14.44, phenylacetaldehyde oxime monooxygenase), this enzyme cannot act on phenylacetaldehyde oximes. It can accept (4-hydroxyphenyl)acetonitrile, (2-methylphenyl)acetonitrile, and (3-methylphenyl)acetonitrile as substrates at a lower rate.
