EC 4.2.3.26

Accepted name: R-linalool synthase

Reaction: geranyl diphosphate + H2O = (3R)-linalool + diphosphate

Glossary: (3R)-linalool = (3R)-3,7-dimethylocta-1,6-dien-3-ol

Other name(s): (3R)-linalool synthase; (–)-3R-linalool synthase

Systematic name: geranyl-diphosphate diphosphate-lyase [(3R)-linalool-forming]

Comments: Geranyl diphosphate cannot be replaced by isopentenyl diphosphate, dimethylallyl diphosphate, farnesyl diphosphate or geranylgeranyl diphosphate as substrate [1]. Requires Mg2+ or Mn2+ for activity. Unlike many other monoterpene synthases, only a single product, (3R)-linalool, is formed.
