ScGS: Streptomyces coelicolor geosmin synthase
Gesomin synthase from Streptomyces coelicolor A3(2) (ScGS) is a single 726-amino acid protein which catalyze the Mg2+ dependent conversion of farnesyl diphosphate to a mixture including geosmin. ScGS is a bifunctional enzyme in which the N-terminal domain catalyze the cyclization of FPP to form germacradienol, while the C-terminal domain then convert this sesquiterpenoid product to geosmin.
Usage and Biology
The ScGS is a bifunctional sesquiterpene cyclase, with the presence of Mg2+, the N-terminal half of this protein catalyzes the ionization and cyclization of farnesyl diphosphate to form germacradienol and inorganic pyrophosphate(PPi). Then the C-terminal domain, highly homologous with the former, catalyzes the protonation, cyclization, and fragmentation of germacradienol to form geosmin and acetone.
