According to the literature [3] & [9], This enzyme catalyzes the following reactions sequentially: (A) Elimination of phosphate group from DMAPP (leading to the formation of carbocation and pyrophosphate): This reaction is rupture of the carbon-oxygen bond of the allylic diphosphate to form a ion pair between the pyrophosphate leaving group and the allylic carboncation. (B) Addition polymerization between the carbocation intermediate and IPP: This reaction is alkylation of the C3-C4 double bond of IPP by the carbocation to form a second carbocationic intermediate, According to the literature [27] & [29], (A) Elimination of phosphate group from DMAPP (leading to the formation of carbocation and pyrophosphate): (A1) The developing negative charge on the eliminated group, (A2) The mainchain carbonyl group of Lys214, (A3) This elimination reaction occurs by E1-like mechanism. |
