SYSTEMATIC NAME 
IUBMB Comments
geranyl-diphosphate diphosphate-lyase [cyclizing, (+)-car-3-ene-forming]
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 [1,2]. In Picea abies (Norway spruce) and Picea sitchensis (Sitka spruce) terpinolene is also formed [4,6]. See EC 4.2.3.113 terpinolene synthase. (+)-Car-3-ene is associated with resistance of Picea sitchensis (Sitka spruce) to white pine weevil [6].
