ID   1.1.99.41
DE   3-hydroxy-1,2-didehydro-2,3-dihydrotabersonine reductase.
AN   T3R.
AN   tabersonine 3-reductase.
CA   (1) (3R)-3-hydroxy-16-methoxy-2,3-dihydrotabersonine + A = (3R)-1,2-
CA   didehydro-3-hydroxy-16-methoxy-2,3-dihydrotabersonine + AH2.
CA   (2) (3R)-3-hydroxy-2,3-dihydrotabersonine + A = (3R)-1,2-didehydro-3-
CA   hydroxy-2,3-dihydrotabersonine + AH2.
CC   -!- This enzyme is involved in the biosynthesis of vindoline and
CC       vindorosine in the plant Catharanthus roseus (Madagascar periwinkle).
CC   -!- In vivo, it functions in the direction of reduction.
CC   -!- It has no activity with 3-epoxylated compounds, which can form
CC       spontaneously from its unstable substrates.
