evolution | the enzyme is a class II diterpene synthase (diTPS), expression profiling and phylogenetic analysis of the CfTPS family. Coleus forskohlii diTPSs constitute a small gene family. Schematic overview of the biosynthetic routes from GGPP to specialized and general diterpenoids of the abietane, labdane, and ent-kaurene class | Plectranthus barbatus |
metabolism | enzyme CfTPS2 synthesizes the intermediate copal-8-ol diphosphate,which in combination with CfTPS3 results in the stereospecific formation of (13R) manoyl oxide, while the combination of CfTPS1 an CfTPS3 or CfTPS4 leads to formation of miltiradiene, precursor of abietane diterpenoids in Coleus forskohlii, in combination with TPS14, (13R) and (13S) manoyl oxides are fomed | Plectranthus barbatus |

physiological function | involvement of CfTPS2 in the formation of (13R) manoyl oxide en route to forskolin in root cork cells | Plectranthus barbatus |
