Fungal aldoxime dehydratase (Oxd) of Fusarium graminearum MAFF305135 was purified and characterized for the first time from its overexpressing Escherichia coli transformant. The enzyme showed about 20% identity with known Oxds, and had similar enzymatic properties with nitrilase-linked Oxd from the Bacillus strain. It belongs to a group of phenylacetaldoxime dehydratases (EC 4.99.1.7), based on its substrate specificity and kinetic analysis.
