Figure 8. Biosynthesis of TIAs and Camptothecin: DXS: 1-deoxyxylulose-5-phosphate; G10H: geraniol 10-hydroxylase; SLS: secologanin synthase; TDC: tryptophan decarboxylase; STR: strictosidine synthases; T16H, tabersonine 16-hydroxylase; D4H: desacetoxyvindoline 4-hydroxylase; DAT: deacetylvindoline 4-O-acetyl transferase; CRPX1: vacuolar class III peroxidase. Dashed lines indicate multiple enzyme conversions.
