ID   1.5.1.31
DE   berberine reductase.
AN   (R)-canadine synthase.
CA   (R)-canadine + 2 NADP(+) = berberine + H(+) + 2 NADPH.
CC   -!- Involved in alkaloid biosynthesis in Corydalis cava to give (R)-
CC       canadine with the opposite configuration to the precursor of
CC       berberine (see EC 1.3.3.8).
CC   -!- Also acts on 7,8-dihydroberberine.
