However, until the present investigations of TEAS, formation of this postulated intermediate has
倍半萜合酶是一个酶家族,可通过替代途径催化法呢基焦磷酸 (FPP) 环化以产生多种环状倍半萜产物。已经提出通过这些酶中的几种,包括烟草 5-表皮马兜铃烯合酶 (TEAS) 进行催化,包括形成作为稳定中间体的锗麦烯 A。在正常催化过程中,无论是锗烯 A 还是任何其他中间体都不会从倍半萜合酶活性位点中释放出来。支持germacrene A 中间体的证据来自对土曲霉和Penicillium roquefortii 马兜铃合成酶的研究(Cane, DE Chem. Rev. 1990, 90, 1089-1103 和其中的参考文献。Cane, DE; Bryant, CJ Am. Chem. Soc. 1994, 116, 12063−12064. Cane, DE; Tsantrizos, YSJ Am. Chem. Soc. 1996, 118, 10037-10040)。然而,直到目前对 TEAS
