EC 4.2.3.25     
Accepted name: S-linalool synthase
Reaction: geranyl diphosphate + H2O = (3S)-linalool + diphosphate
For diagram of acyclic monoterpenoid biosynthesis, click here
Glossary: (3S)-linalool = (3S)-3,7-dimethylocta-1,6-dien-3-ol
Other name(s): LIS; Lis; 3S-linalool synthase
Systematic name: geranyl-diphosphate diphosphate-lyase [(3S)-linalool-forming]
Comments: Requires Mn2+ or Mg2+ for activity. Neither (S)- nor (R)-linalyl diphosphate can act as substrate for the enzyme from the flower Clarkia breweri [1]. Unlike many other monoterpene synthases, only a single product, (3S)-linalool, is formed.
