Accepted name: (–)-pluviatolide 4-O-methyltransferase
Reaction: S-adenosyl-L-methionine + (–)-pluviatolide = S-adenosyl-L-homocysteine + (–)-bursehernin
Glossary: (–)-pluviatolide = (3R,4R)-4-(2H-1,3-benzodioxol-5-ylmethyl)-3-[(4-hydroxy-3-methoxyphenyl)methyl]oxolan-2-one
(–)-bursehernin = (3R,4R)-4-(2H-1,3-benzodioxol-5-ylmethyl)-3-[(3,4-dimethoxyphenyl)methyl]oxolan-2-one
Other name(s): OMT3 (gene name)
Systematic name: S-adenosyl-L-methionine:(–)-pluviatolide 4-O-methyltransferase
Comments: The enzyme, characterized from the plant Sinopodophyllum hexandrum, is involved in the biosynthetic pathway of podophyllotoxin, a non-alkaloid toxin lignan whose derivatives are important anticancer drugs.
