We describe the characterisation of the O-methyltransferase JerF from the late stages of jerangolid biosynthesis. JerF is the first known example of an enzyme that catalyses the formation of a non-aromatic, cyclic methylenolether. The enzyme was overexpressed in E. coli and the cell-free extracts were used in bioconversion experiments. Chemical synthesis gave access to a series of substrate surrogates
我们描述了 jerangolid 生物合成后期的 O-甲基转移酶 JerF 的特征。JerF 是第一个已知的催化非芳香族环状亚甲基醚形成的酶的例子。该酶在大肠杆菌中过表达,无细胞提取物用于生物转化实验。化学合成提供了一系列覆盖广泛结构空间的底物替代物。酶促测定显示 JerF 具有广泛的底物耐受性和高区域选择性,这使其成为化学酶促合成应用的有吸引力的候选者,尤其适用于 4-甲氧基-5,6-二氢-2H-吡喃-2-one 的后期应用- 含有天然产物。
