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.
