EC 4.2.3.201     
Accepted name: hydropyrene synthase
Reaction: geranylgeranyl diphosphate = hydropyrene + diphosphate
Glossary: hydropyrene = (1R,3aR,3a1R,5aR,5a1S,8aS,10aS)-1,5a,8a-trimethyl-4-methylidenehexadecahydropyrene
Other name(s): HpS
Systematic name: geranylgeranyl-diphosphate diphosphate-lyase (cyclizing, hydropyrene-forming)
Comments: Isolated from the bacterium Streptomyces clavuligerus. The 1-proR hydrogen atom of geranylgeranyl diphosphate is lost in the reaction. The enzyme also produces hydropyrenol, isoelisabethatriene and traces of other diterpenoids. cf. EC 4.2.3.202, hydropyrenol synthase, and EC 4.2.3.203, isoelisabethatriene synthase.
