EC 2.3.1.160 Details
EC number
2.3.1.160
Accepted name
vinorine synthase
Reaction
acetyl-CoA + 16-epivellosimine = CoA + vinorine
Systematic name
acyl-CoA:16-epivellosimine O-acetyltransferase (cyclizing)
CAS registry number
88844-97-7
Comment
The reaction proceeds in two stages. The indole nitrogen of 16-epivellosimine interacts with its aldehyde group giving an hydroxy-substituted new ring. This alcohol is then acetylated. Also acts on gardneral (11-methoxy-16-epivellosimine). Generates the ajmalan skeleton, which forms part of the route to ajmaline.
