Figure 6From: Positive Darwinian selection is a driving force for the diversification of terpenoid biosynthesis in the genus OryzaProposed reaction mechanism for the formation of sesquiterpene products by OryzaTPS1s. These enzymes displayed three types of biochemical activities using farnesyl pyrophosphate as the substrate: (E)-β-caryophyllene synthase (ECS), (E)-β-caryophyllene/germacrene A synthase (EGS), and the germacrene D & germacrene A synthase (DAS). The minor product α-humulene was not considered in the reaction path.Back to article page
