Functional diversity of 2-oxoglutarate/Fe(II)-dependent dioxygenases in plant metabolism [PDF]

open access: yes, 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,
