A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
(+)-alpha-pinene synthase.
Alternative Name(s)
(+)-alpha-pinene cyclase.
Reaction catalysed
Geranyl diphosphate <=> (+)-alpha-pinene + diphosphate
  • Cyclase I of Salvia officinalis (sage) gives about equal parts (+)- alpha-pinene and (+)-camphene, whereas cyclase III gives about equal parts of (+)-alpha-pinene and (+)-beta-pinene.
  • (3R)-linalyl diphosphate can also be used by the enzyme in preference to (3S)-linalyl diphosphate.
  • The 4-pro-R hydrogen of geranyl diphosphate is lost.
  • With synthase II of Pinus taeda (loblolly pine) (+)-beta-pinene was the only product.
