来自反式酰基转移酶聚酮酶(trans-AT PKS)的酶核心组分催化异常多样的生物合成转化以产生结构复杂的生物活性化合物。在这里,我们重点关注在各种反式AT PKS途径中发现的一组加氧酶,包括pederin、卵环素和Toblerol的加氧酶。使用来自Serratia muthica 4Rx13的卵环素途径同源物(OocK)和N-乙酰半胱胺(SNAC)硫酯作为酰基载体蛋白(ACP)栓系中间体的测试替代物,我们表明该酶将氧插入β-酮酰基部分以产生丙二酰酯SNAC产物。基于这些数据和一个非水解的卵胞素同源物与保留酯部分的鉴定,我们提出了一个统一的生物合成途径的卵胞素,haterumalides,和biselides。通过提供进入内部酯、羧酸酯假起始物和末端羟基官能团的途径,氧插入到聚酮骨架中极大地扩展了PKS的生物合成范围。
Enzymatic core components from trans‐acyltransferase polyketide synthases (trans‐AT PKSs) catalyze exceptionally diverse biosynthetic transformations to generate structurally complex bioactive compounds. Here we focus on a group of oxygenases identified in various trans‐AT PKS pathways, including those for pederin, oocydins, and toblerols. Using the oocydin pathway homologue (OocK) from Serratia plymuthica 4Rx13 and N‐acetylcysteamine (SNAC) thioesters as test surrogates for acyl carrier protein (ACP)‐tethered intermediates, we show that the enzyme inserts oxygen into β‐ketoacyl moieties to yield malonyl ester SNAC products. Based on these data and the identification of a non‐hydrolyzed oocydin congener with retained ester moiety, we propose a unified biosynthetic pathway of oocydins, haterumalides, and biselides. By providing access to internal ester, carboxylate pseudostarter, and terminal hydroxyl functions, oxygen insertion into polyketide backbones greatly expands the biosynthetic scope of PKSs.
