EC 4.2.3.180     
Accepted name: pseudolaratriene synthase
Reaction: geranylgeranyl diphosphate = pseudolaratriene + diphosphate
Glossary: pseudolaradiene = (1RS,3aSR,8aRS)-3a,6-dimethyl-1-(6-methylhepta-2,5-dien-2-yl)-1,2,3,3a,4,7,8,8a-octahydrohydroazulene
Other name(s): PxaTPS8
Systematic name: geranylgeranyl-diphosphate diphosphate-lyase (cyclizing, pseudolaradiene-forming)
Comments: Isolated from the plant Pseudolarix amabilis (golden larch). The product is oxidized to pseudolaric acid B, a microtubule-destabilizing agent.
