Valencene synthase
Class of enzymes
From Wikipedia, the free encyclopedia
Valencene synthase (EC 4.2.3.73) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase (valencene-forming).[1] It is a terpene cyclase enzyme responsible for the biosynthesis of valencene, a sesquiterpene, using farnesyl pyrophosphate as its substrate. The first such enzyme was isolated using orange cDNA.[2] This enzyme catalyses the following chemical reaction
- (2E,6E)-farnesyl diphosphate (+)-valencene + diphosphate
