SYSTEMATIC NAME
IUBMB Comments
(S)-tetrahydrocolumbamine,NADPH:oxygen oxidoreductase (methylenedioxy-bridge-forming)
A heme-thiolate enzyme (P-450) catalysing an oxidative reaction that does not incorporate oxygen into the product. Oxidation of the methoxyphenol group of the alkaloid tetrahydrocolumbamine results in the formation of the methylenedioxy bridge of canadine.

GENERAL INFORMATION

UNIPROT
COMMENTARY hide
LITERATURE
malfunction
-
virus-induced gene silencing of CYP719A21 causes a significant increase in (S)-tetrahydrocolumbamine accumulation and a corresponding decrease in the levels of putative downstream intermediates and noscapine
physiological function
CYP719A13 can be involved in both sanguinarine and berberine formation in Argemone mexicana
