physiological function | the enzyme is a multifunctional P450 catalyzing dehydration of (Z)-4-hydroxyphenylacetaldoxime to 4-hydroxyphenylacetonitrile and C-hydroxylation of 4-hydroxyphenylacetonitrile during biosynthesis of the cyanogenic glucoside beta-D-glucopyranosyloxy-(S)-4-hydroxymandelonitrile (dhurrin) | Sorghum bicolor |
