derivatives) than provided by their oligoprenyl diphosphate precursor. This is sometimes the result of an oxidative ring-opening reaction at a terpene-cyclase-derived molecule containing the regular number of Me group equivalents, as observed for picrotoxan sesquiterpenes. In this study a sesquiterpene cyclase from Trichoderma spp. is described that can convert farnesyl diphosphate (FPP) directly via a remarkable
某些类萜的骨架不寻常,因为它们包含比它们的异戊二烯基二磷酸酯前体所提供的更多的Me基团(或它们的生物合成等价物,例如亚烷基,羟甲基,醛或羧酸及其衍生物)。有时这是在萜烯环化酶衍生的分子上发生氧化性开环反应的结果,该分子含有规则数量的Me基团当量,如对于吡咯烷酮倍半萜烯所观察到的。在这项研究中,木霉属的倍半萜环化酶。据描述,它可以通过显着的骨架重排直接将法呢基二磷酸酯(FPP)转化为三chobrasilenolol,一种新的Brasil倍半萜烯,与FPP相比具有一个额外的Me基等价物。
