Carboxylating enoyl‐thioester reductases (ECRs) are a recently discovered class of enzymes. They catalyze the highly efficient addition of CO2 to the double bond of α,β‐unsaturated CoA‐thioesters and serve two biological functions. In primary metabolism of many bacteria they produce ethylmalonyl‐CoA during assimilation of the central metabolite acetyl‐CoA. In secondary metabolism they provide distinct

incorporation of l-glutamate to acyl-coenzyme A substrates. Combined with Alb29 and Mgr36 (an acyl-coenzyme A ligase), a one-pot enzymatic system was established to synthesize seven α-amino ketones. When these α-amino ketones were fed into the alb29 knockout strain Δalb29, respectively, the albogrisin analogs with different side chains were observed.
Alb29 是一种 α-氧代胺合酶,参与Streptomyces albogriseolus MGR072中的 albogrisin 生物合成,被表征并负责将l-谷氨酸掺入酰基辅酶 A 底物。结合Alb29和Mgr36(一种酰基辅酶A连接酶),建立了一锅法合成七个α-氨基酮。当这些α-氨基酮分别加入alb29敲除菌株Δalb29时,观察到具有不同侧链的albogrisin类似物。
