ENZYME entry: EC 4.2.3.107
| Accepted Name |
|---|
| (+)-car-3-ene synthase.
|
| Alternative Name(s) |
|---|
| 3-carene cyclase. |
| Reaction catalysed |
|---|
| Geranyl diphosphate <=> (+)-car-3-ene + diphosphate |
| Comment(s) |
|---|
- The enzyme reacts with (3S)-linalyl diphosphate twice as rapidly as
geranyl diphosphate, but 25 times as rapidly as (3R)-linalyl
diphosphate.
- It is assumed that (3S)-linalyl diphosphate is normally formed as an
enzyme bound intermediate in the reaction.
- In the reaction the 5-pro-R hydrogen of geranyl diphosphate is
eliminated during cyclopropane ring formation.
- In Picea abies (Norway spruce) and Picea sitchensis (Sitka spruce)
terpinolene is also formed.
- See EC 4.2.3.113.
- (+)-car-3-ene is associated with resistance of Picea sitchensis
(Sitka spruce) to white pine weevil.
