Regiospecifically labeled geranyl diphosphates ((2E,6E)-[1,1,8,8,8-(2)H(5)]- and (2E,6Z)-[1,1,9,9,9-(2)H(5)]-GDP) and D(2)O incorporation, in concert with NMR spectrometry, were employed to demonstrate a unique intramolecular syn-facial protonation-cyclization mechanism of action of 1,8-cineole synthase. |
