IntEnz Enzyme Nomenclature


Accepted name:
pentalenene synthase
Other name:
pentalenene synthetase
Systematic name:
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, pentalenene-forming)



Isolated from Streptomyces avermitilis. The enzyme is involved in the biosynthesis of pentalenolactone and related antibiotics. The 9si hydrogen of farnesyl diphosphate undergoes a 1,2-hydride shift where it becomes the 1α hydrogen of pentalenene.
