Glossary: (–)-matairesinol = 3R,4R)-3,4-bis[(4-hydroxy-3-methoxyphenyl)methyl]oxolan-2-one
(–)-pluviatolide = ((3R,4R)-4-(2H-1,3-benzodioxol-5-ylmethyl)-3-[(4-hydroxy-3-methoxyphenyl)methyl]oxolan-2-one

Other name(s): CYP719A23 (gene name)

Systematic name: (–)-matairesinol,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (methylenedioxy-bridge-forming)

Comments: A cytochrome P-450 (heme-thiolate) protein. The enzyme from the plants Sinopodophyllum hexandrum and Podophyllum peltatum catalyses the formation of a methylenedioxy-bridge. It is involved in the biosynthesis of podophyllotoxin, a non-alkaloid toxin lignan whose derivatives are important anticancer drugs.
