A P-450 (heme-thiolate) protein. This enzyme is involved in the biosynthesis of the cyanogenic glucoside dhurrin in sorghum, along with EC 1.14.13.68, 4-hydroxyphenylacetaldehyde oxime monooxygenase and EC 2.4.1.85, cyanohydrin β-glucosyltransferase. Some 2-(4-hydroxyphenyl)-1-nitroethane is formed as a side product.
