|
| Alternative Name(s) |
|---|
| T3R. |
| tabersonine 3-reductase. |
| Reaction catalysed |
|---|
- (3R)-3-hydroxy-16-methoxy-2,3-dihydrotabersonine + A <=> (3R)-1,2-didehydro-3-hydroxy-16-methoxy-2,3-dihydrotabersonine + AH2

|
| Comment(s) |
|---|
- This enzyme is involved in the biosynthesis of vindoline and
vindorosine in the plant Catharanthus roseus (Madagascar periwinkle).
- In vivo, it functions in the direction of reduction.
- It has no activity with 3-epoxylated compounds, which can form
spontaneously from its unstable substrates.
