E-3-Methyl-3-pentenyl diphosphate acted as an artificial substrate in the reaction with E,E-farnesyl diphosphate catalyzed by undecaprenyl diphosphate synthase of . The synthase reaction with this substrate proceeded in the same stereochemical manner as that with the natural substrate, 3-methyl-3-butenyl diphosphate, but it had a full stop at the stage of one step condensation, thereby forming a chiral
E-3-甲基-3-戊烯基二磷酸酯在与α,癸烯基二磷酸合酶催化的E,E-法呢基二磷酸酯的反应中充当人工底物。与该底物的合酶反应以与天然底物3-甲基-3-丁烯基二磷酸相同的立体化学方式进行,但在一步缩合阶段具有完全的终止,从而形成手性化合物(Z ,E,E)-(S)-4-甲基香叶基香叶基二磷酸酯。
