Accepted name: cycloaraneosene synthase
Reaction: geranylgeranyl diphosphate = cycloaraneosene + diphosphate
Glossary: cycloaraneosene = (1R,3aR,9aS,10aR)-1,9a-dimethyl-4-methylene-7-(propan-2-yl)-1,2,3,3a,4,5,6,8,9,9a,10,10a-dodecahydrodicyclopenta[a,d][8]annulene
Other name(s): SdnA
Systematic name: geranylgeranyl-diphosphate diphosphate-lyase (cycloaraneosene-forming)
Comments: Isolated from the fungus Sordaria araneosa. Cycloaraneosene is a precursor of the antibiotic sordarin.
