Glossary: (–)-yatein = (3R,4R)-4-(1,3-benzodioxol-5-ylmethyl)-3-(3,4,5-trimethoxybenzyl)dihydrofuran-2(3H)-one
(–)-deoxypodophyllotoxin = (5R,5aR,8aR)-5-(3,4,5-trimethoxyphenyl)-5,8,8a,9-tetrahydrofuro[3',4':6,7]naphtho[2,3-d][1,3]dioxol-6(5a)-one

Other name(s): 2-ODD (gene name)

Systematic name: (–)-yatein,2-oxoglutarate:oxygen oxidoreductase (ring-forming)

Comments: The enzyme, characterized from the plant Sinopodophyllum hexandrum (mayapple), is involved in the biosynthetic pathway of podophyllotoxin, a non-alkaloid toxin lignan whose derivatives are important anticancer drugs. It catalyses the closure of the central six-membered ring in the aryltetralin scaffold.
