Enzymatic synthesis of isotopically labeled isoprenoid diphosphates.
Recombinant yeast isopentenyl diphosphate (IPP) isomerase and avian farnesyl diphosphate (FPP) synthase from overproducing strains of Escherichia coli were used to synthesize FPP from IPP and dimethylallyl diphosphate (DMAPP). [2,4,5-13C3]IPP and [2,4,5-13C3]DMAPP were synthesized from ethyl [2-13C]bromoacetate and [1,3-13C2]acetone. Thes compounds were used as substrates for enzymatic synthesis of FPP selectivity labeled at the first or third isoprene residue or at all three.
