discovered a novel, spontaneous model oxidation that leads to a powerful base capable of carrying out a carbon-carbon bond forming condensation reaction analogous to that observed in the vitamin K-mediated carboxylation of glutamate. The model sequence incorporates a novel base-strength enhancement sequence and it implicates molecular oxygen as the initiating factor in the vitamin K-dependent carboxylation
我们发现了一种新的自发模型氧化,它产生了一种强大的碱,能够进行碳-碳键形成缩合反应,类似于在维生素 K 介导的谷氨酸羧化中观察到的反应。该模型序列包含一个新的碱基强度增强序列,它暗示分子氧是维生素 K 依赖性羧化的起始因子。当在 (18)O2 气氛下进行氧化时,两个 (18)O 原子会结合到维生素 K 氧化物产品中。选择性 (18)O 标记将甲基旁边的羰基定义为维生素 K 的活性位点。
