Cyclase I of?Salvia officinalis?(sage) gives about equal parts (+)-¦Á-pinene and (+)-camphene, whereas cyclase III gives about equal parts of (+)-¦Á-pinene and (+)-¦Â-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. Requires Mg2+?(preferred to Mn2+) [1-4]. With synthase II of?Pinus taeda?(loblolly pine) (+)-¦Â-pinene was the only product [5,6]. Requires Mn2+?(preferred to Mg2+). See also EC?4.2.3.122, (+)-¦Â-pinene synthase, and EC?4.2.3.116, (+)-camphene synthase. |
