FIGURE 1.
Functional role of PR. PR is located in a side route branching from the ajmaline biosynthetic pathway leading to dihydroperaksine and extends the metabolic network of Rauvolfia monoterpenoid indole alkaloids. (STR1, strictosidine synthase, EC 4.3.3.2; PNAE, polyneuridine aldehyde esterase, EC 3.1.1.78; VS, vinorine synthase, EC 2.3.2.160; VH, vinorine hydroxylase, EC 1.14.13.75; CPR, cytochrome P450 reductase; H+ = transformation under acidic conditions).
