Accepted name: nephthenol synthase
Reaction: geranylgeranyl diphosphate + H2O = (R)-nephthenol + diphosphate
For diagram of cembrene and related diterpenoids, click here
Glossary: (R)-nephthenol = 2-[(1R,3E,7E,11E)-4,8,12-trimethyltetradeca-3,7,11-trien-1-yl]propan-2-ol
Other name(s): DtcycA (gene name); DtcycB (gene name)
Systematic name: geranylgeranyl-diphosphate diphosphate-lyase [(R)-nephthenol-forming]
Comments: Requires Mg2+. Two isozymes with this activity were isolated from the bacterium Streptomyces sp. SANK 60404. The enzyme encoded by the DtcycA gene also produces cembrene C (see EC, cembrene C synthase), while the enzyme encoded by the DtcycB gene also produces (R)-cembrene A and (1S,4E,8E,12E)-2,2,5,9,13-pentamethylcyclopentadeca-4,8,12-trien-1-ol (see EC, cembrene A synthase, and EC, pentamethylcyclopentadecatrienol synthase).
