| Name |
(S)-stylopine synthase;
(S)-cheilanthifoline oxidase (methylenedioxy-bridge-forming) |
| Class |
Oxidoreductases;
Acting on paired donors, with O2 as oxidant and incorporation or
reduction of oxygen. The oxygen incorporated need not be derived
from O2;
With NADH or NADPH as one donor, and the other dehydrogenated
 |
| Sysname |
(S)-cheilanthifoline,NADPH:oxygen oxidoreductase
(methylenedioxy-bridge-forming) |
| Reaction(IUBMB) |
(S)-cheilanthifoline + NADPH + H+ + O2 = (S)-stylopine + NADP+ + 2
H2O [RN:R04690] |

| Substrate |
(S)-cheilanthifoline [CPD:C05174];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007] |
| Product |
(S)-stylopine [CPD:C05175];
NADP+ [CPD:C00006];
H2O [CPD:C00001] |
| Comment |
A heme-thiolate enzyme (P-450) catalysing an oxidative reaction that
does not incorporate oxygen into the product. Forms the second
methylenedioxy bridge of the protoberberine alkaloid stylopine from
oxidative ring closure of adjacent phenolic and methoxy groups of
cheilanthifoline. |
