Figure 5. Mass spectra (A–C) and structures (D) of DdTPS8 products and CYP521A1 products derived from unlabeled farnesyl diphosphate (FDP) (A), 13C15-FDP (B), and 1,1–2 H2,11–13C-FDP (C + D).

The genes were coexpressed in E. coli Bl21-DE3-Star together with the P450 reductase gene RedB. Crude protein extracts were incubated with unlabeled or labeled (E,E)-FDP and volatile enzyme products were collected from the headspace of the assays using PDMS tubes. Product analysis was performed with GC-TDU-MS. See also Figure 5—figure supplement 1.
