Fig. 3From: Structure-function analysis of CYP719As involved in methylenedioxy bridge-formation in the biosynthesis of benzylisoquinoline alkaloids and its de novo productionResults of in vitro enzyme assay of CyCYP719As. The column graph indicated the conversion rate relative to the added substrate. A CyCYP719As catalyzed the conversion of (S)-scoulerine 1 to (S)-stylopine 3. B CyCYP719As catalyzed the conversion of (S)-tetrahydrocolumbamine 4 to (S)-tetrahydroberberine 5. Data reported are the means ± SD from triplicate analyses. ** indicates P < 0.01; nd, not detectedBack to article page
