(S)-Mosher esters. The steady state kinetic parameters were k(cat) 0.040 +/- 0.001 s(-1) and K(m) 1.06 +/- 0.11 microM. Individual incubations of recombinant avermitilol synthase with [1,1-(2)H(2)]FPP (1a), (1S)-[1-(2)H]-FPP (1b), and (1R)-[1-(2)H]-FPP (1c) and NMR analysis of the resulting avermitilols supported a cyclization mechanism involving the loss of H-1(re) to generate the intermediate bicyclogermacrene
