The enzyme (âÂÂ)-endo-Fenchol synthase (EC 4.2.3.10) catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is geranyl-diphosphate diphosphate-lyase [cyclizing, (âÂÂ)-endo-fenchol-forming]. Other names in common use include (âÂÂ)-endo-fenchol cyclase, and geranyl pyrophosphate:(âÂÂ)-endo-fenchol cyclase. This enzyme participates in monoterpenoid biosynthesis.
