Functional Characterization of Sesquiterpene Synthase from Polygonum minus
Figure 8
A simplified version of the sesquiterpene biosynthetic pathway. This pathway shows the predicted flux of substrate (IPP and FPP) to produce more sesquiterpenes (C15) in transgenic plants overexpressing the PmSTS gene. (+) indicates the increased flux of substrate and (−) indicates the decreased flux of substrate. GA3P: glyceraldehyde 3-phosphate. HMG-CoA: 3-hydroxy-3-methylglutaryl-CoA. DXR: 1-deoxy-D-xylulose 5-phosphate reductoisomerase. MVA: mevalonate acid. MEP: methyl erythritol phosphate. IPP: isopentyl pyrophosphate and its isomer DMAPP: dimethylallyl diphosphate. FPP: farnesyl diphosphate. GGPP: geranylgeranyl diphosphate (modified from Okada et al. [31] and Vickers et al. [32]).
