在这一期的《化学与生物学》中,提出了一种新的羟醛开关机制用于III型聚酮化合物的生物合成,其中包括在彩色水果中发现的许多抗氧化剂[1]。基于结构和诱变研究,羟醛开关机制表明,电子效应之间的平衡在III型聚酮酶的两个竞争性环化特异性。一个新的假说也被用来解释芪羧酸的生物合成。
In this issue ofChemistry & Biology, a novel Aldol-Switch mechanism is proposed for the biosynthesis of type III polyketides, which include many antioxidants found in colorful fruits [1]. Based on structural and mutagenesis studies, the Aldol-Switch mechanism suggests that electronic effects balance between two competing cyclization specificities in Type III polyketide synthases. A novel hypothesis is also used to explain stilbenecarboxylate biosynthesis.
