WebJan 19, 1999 · Flavonoid 3′,5′-hydroxylase (F3′5′H) is a cytochrome P450 enzyme (Cyt P450) that catalyzes the 3′,5′-hydroxylation of dihydroflavonols, the precursors of purple anthocyanins. Species such as rose and carnation lack F3′5′H activity and are, therefore, unable to generate purple or blue flowers. CYP450 enzymes belong to a superfamily which in humans is composed of at least 57 CYPs; within this superfamily, members of six CYP4A subfamilies, (which are CYP4A, CYP4B, CYP4F, CYP4V, CYP4X, and CYP4z) possess ω-hydroxylase activity viz., CYP4A, CYP4B, and CYP4F CYP2U1 also possesses ω hydroxylase activity.
