PURL: https://purl.expasy.org/enzyme/EC/4.2.3.120
Accepted Name
(-)-beta-pinene synthase
Alternative Name(s)
(-)-(1S,5S)-pinene synthase
beta-geraniolene synthase
Reaction catalysed
(2E)-geranyl diphosphate = (1S,5S)-beta-pinene + diphosphate
Comment(s)
  • Cyclase II of Salvia officinalis (sage) produces about equal parts (-)-alpha-pinene, (-)-beta-pinene and (-)-camphene, plus traces of other monoterpenoids.
  • The enzyme can also use (3S)-Linalyl diphosphate (preferred to (3R)- linalyl diphosphate).
  • The enzyme from Abies grandis (grand fir) produces roughly equal parts of (-)-alpha-pinene and (-)-beta-pinene.
  • Cyclase IV from Pinus contorta (lodgepole pine) produces 63% (-)- beta-pinene, 26% 3-carene, and traces of alpha-pinene.
  • Synthase III from Pinus taeda (loblolly pine) forms (-)-beta-pinene with traces of alpha-pinene.
  • A cloned enzyme from Artemisia annua (sweet wormwood) gave (-)-beta- pinene with traces of (-)-alpha-pinene.
  • The enzyme from Picea sitchensis (Sika spruce) forms 30% (-)-beta- pinene and 70% (-)-alpha-pinene.
  • See also EC 4.2.3.119, EC 4.2.3.117 and EC 4.2.3.107.
  • Formerly EC 4.1.99.8 and EC 4.2.3.14.
