Systematic name:
(+)-pinoresinol,[reduced NADPH-hemoprotein reductase]:oxygen oxidoreductase (cyclizing)
Reactions
- (1) (+)-pinoresinol + reduced NADPH-hemoprotein reductase + O2 = (+)-piperitol + oxidized NADPH-hemoprotein reductase + 2 H2O
- (2) (+)-piperitol + reduced NADPH-hemoprotein reductase + O2 = (+)-sesamin + oxidized NADPH-hemoprotein reductase + 2 H2O
Comments:
A cytochrome P450 (heme-thiolate) protein. Isolated from Sesamum indicum (sesame) and S.radiatum (black sesame).
