This cytochrome P-450 (heme thiolate) enzyme is involved in the biosynthesis of the cyanogenic glucoside dhurrin in sorghum. It catalyses three different activities – isomerization of the (E) isomer to the (Z) isomer, dehydration, and C-hydroxylation. This enzyme is involved in the biosynthesis of the cyanogenic glucoside dhurrin in sorghum, along with EC 1.14.13.41, tyrosine N-monooxygenase and EC 2.4.1.85, cyanohydrin ¦Â-glucosyltransferase.
