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, (−)-endo-fenchol-forming]. Other names in common use include (−)-endo-fenchol cyclase, and geranyl pyrophosphate:(−)-endo-fenchol cyclase. This enzyme participates in monoterpenoidbiosynthesis.
