WebJul 28, 2024 · Using benzyltriethylammonium cation (BTAC) to simulate the reaction intermediate bisabolyl cation, it was found that the cation intermediate is stabilized by the electrostatic action of pyrophosphate anion and the cation–π interactions of F95, F96, and F198. Mutation of these aromatic amino acid residues will break such stabilizing effects ... WebDec 18, 2012 · The precursor for (−)-curlone would have to be produced from the (R)-bisabolyl cation via a C7/C1 1,3-hydride shift. Thus, (−)-curlone synthesis (should it occur in nature) likely does not involve ST00A/ST00B, which appears to utilize only the (S)-bisabolyl cation as an enzyme-bound intermediate.
