A highly sought after reaction in chemical synthesis is the activation of unactivated carbon-hydrogen bonds. We demonstrate the hydroxylation of fatty acids using an engineered thermostable archaeal cytochrome P450 enzyme. By replacing a seven amino acid section of the I-helix, the nicotinamide cofactor-dependent monooxygenase was converted into a hydrogen peroxide using peroxygenase, enabling the efficient biocatalytic oxidation of C-H bonds at room temperature to 90 °C.
在化学合成中，人们非常追求的一个反应是激活未活化的碳-氢键。我们利用一种经过工程改造的耐热古菌细胞色素 P450 酶来实现脂肪酸的羟化。通过替换 I 螺旋的七个氨基酸部分，这个依赖烟酰胺辅酶的单加氧酶被转化为过氧化物酶，从而能够在室温至 90°C 的温度下，有效利用过氧酶将 C-H 键高效生物催化氧化。
