Enzymes in biosynthetic pathways, especially in plant and microbial metabolism, generate structural and functional group complexity in small molecules by conversion of acyclic frameworks to cyclic scaffolds via short, efficient routes. The distinct chemical logic used by several distinct classes of cyclases, oxidative and non-oxidative, has recently been elucidated by genome mining, heterologous expression, and genetic and mechanistic analyses. These include enzymes performing pericyclic transformations, pyran synthases, tandem acting epoxygenases, and epoxide “hydrolases”, as well as oxygenases and radical S-adenosylmethionine enzymes that involve rearrangements of substrate radicals under aerobic or anaerobic conditions.

酶促复杂性生成的最新进展:环化反应



生物合成途径中的酶,特别是植物和微生物代谢中的酶,通过短而有效的途径将无环框架转化为环状支架,从而在小分子中产生结构和功能组的复杂性。最近通过基因组挖掘、异源表达以及遗传和机制分析阐明了几种不同类别的环化酶(氧化性和非氧化性)所使用的独特化学逻辑。这些包括进行周环转化的酶、吡喃合酶、串联作用环氧化酶和环氧化物“水解酶”,以及涉及有氧或厌氧条件下底物自由基重排的加氧酶和自由基S-腺苷甲硫氨酸酶。
