2.3.1.74 | 3 malonyl-CoA + 4-coumaroyl-CoA = 4 CoA + naringenin chalcone + 3 CO2 |
reaction mechanism analysis by quantum mechanics calculations, overview. In loading step, only a tetrahedral intermediate is located without transition state. His303 acts as a H31 donor, but not a hydrogen bond donor, to stabilize the intermediate formation. In decarboxylation step, the reaction proceeds via a transition state and is sensitive to the environment. In elongation step, a tetrahedral transition state is located, structure-function analysis, overview |
