Functional diversity of 2-oxoglutarate/Fe(II)-dependent dioxygenases in plant metabolism [PDF]
, 2014 Oxidative enzymes catalyze many different reactions in plant metabolism. Among this suite of enzymes are the 2-oxoglutarate/Fe(II)-dependent dioxygenases (2-ODDs). Cytochromes P450 (CYPs) as often considered the most versatile oxidative enzymes in nature,

Thebaine Synthase: A New Enzyme in the Morphine Pathway in
Natural Product Communications, 2007 Along the poppy morphine biosynthetic pathway, the transition from salutaridinol-7-O-acetate to thebaine had previously been claimed to proceed non-enzymatically between pH 8–9. At pH 6–7, the acetate was transformed to an azonine derivative.
