IUBMB Enzyme Nomenclature


Accepted name: β-thujene synthase

Reaction: geranyl diphosphate = β-thujene + diphosphate

For diagram of reaction click here

Other name(s): CoTPS1

Systematic name: geranyl-diphosphate diphosphate-lyase (cyclizing, β-thujene-forming)

Comments: Isolated from the plant Cananga odorata var. fruticosa (ylang ylang). The enzyme forms roughly equal proportions of β-thujene, sabinene, β-pinene and α-terpinene see EC sabinene synthase, EC β-pinene synthase, EC α-terpinene synthase.
