Recombinant Technology
Farnesyl diphosphate synthase (FPPS) of yeast has been coupled to patchoulol synthase (PTS) of plant origin (P. cablin). Expression of the fusion proteins in S. cerevisiae increased the production of patchoulol, the main sesquiterpene produced by PTS, up to 2-fold.68 Incubations of isotopically pure (2-(2) H (1)) (E, E)-farnesyl diphosphate with recombinant patchoulol synthase (PTS) from P. cablin afforded a 65:35 mixture of monodeuterated and dideuterated patchoulols as well as numerous sesquiterpene hydrocarbons. Extensive NMR analyses of the labeled patchoulol mixture and comparisons of the spectra with those of unlabeled alcohol led to the conclusion that the deuterium label was located at positions (patchoulol numbering system) C5 (both isotopomers, ca. 100%) and C12 (minor isotopomer, 30-35%), that is approximately 2:1 mixture of (5-(2)H(1))- and (5,12-(2)H(2)-patchoulols
