1.5.1.27 |
Accepted name: |
1,2-dehydroreticulinium reductase (NADPH) |
Reaction: |

Other name(s): |
1,2-dehydroreticulinium ion reductase |
Systematic name: |
(R)-reticuline:NADP+ oxidoreductase |
Comments: |
Reduces the 1,2-dehydroreticulinium ion to (R)-reticuline, which is a direct precursor of morphinan alkaloids in the poppy plant. The enzyme does not catalyse the reverse reaction to any significant extent under physiological conditions. |
