()-vetispiradiene,[reduced NADPH-hemoprotein reductase]:oxygen 2alpha-oxidoreductase
A cytochrome P-450 (heme-thiolate) protein. The enzyme from the plant Hyoscymus muticus also hydroxylates valencene at C-2 to give the alpha-hydroxy compound, nootkatol, and this is converted into nootkatone. 5-Epiaristolochene and epieremophilene are hydroxylated at C-2 to give a 2beta-hydroxy derivatives that are not oxidized further.
