GC spectrum of the in vitro analysis of AcTPS1 enzyme function. The AcTPS1 enzymatic product is shown as a blank arrow. Blank, solvent hexane; Vector + FPP, pET-45b cell extracts reacting with the substrate FPP; AcTPS1 + FPP, AcTPS1 protein cell extracts reacting with the substrate FPP. AcTPS1 + FPP was concentrated tenfold for detection
