electron‐rich isonitrile is an important functionality in bioactive natural products, but its biosynthesis has been restricted to the IsnA family of isonitrile synthases. We herein provide the first structural and biochemical evidence of an alternative mechanism for isonitrile formation. ScoE, a putative non‐heme iron(II)‐dependent enzyme from Streptomyces coeruleorubidus, was shown to catalyze the conversion
富电子异腈是具有生物活性的天然产物中的重要功能,但其生物合成仅限于IsnA异腈合酶家族。我们在此提供了异腈形成的另一种机制的第一结构和生化证据。ScoE是一种来自蓝藻链霉菌的推定的非血红素铁(II)依赖性酶,已显示可通过(S)E催化(R)-3-((羧甲基)氨基)丁酸向(R)-3-异氰基丁酸的转化。氧化脱羧机理。这项工作进一步为生物合成一类独特的异腈脂肽提供了一种经过修订的方案,该方案的几个成员对于致病性分枝杆菌的毒力至关重要。
