EC 4.2.3.151     
Accepted name: pentamethylcyclopentadecatrienol synthase

Other name(s): DtcycB (gene name)
Systematic name: geranylgeranyl-diphosphate diphosphate-lyase [(1S,4E,8E,12E)-2,2,5,9,13-pentamethylcyclopentadeca-4,8,12-trien-1-ol-forming]
Comments: Requires Mg2+. Isolated from the bacterium Streptomyces sp. SANK 60404. This trifunctional enzyme, which contains a [4Fe-4S] cluster, also produces (R)-nephthenol and (R)-cembrene A. See EC 4.2.3.150, cembrene A synthase and EC 4.2.3.149, nephthenol synthase.
