The selective hydroxylation of benzene to phenol, without the formation of side products resulting from overoxidation, is catalyzed by cytochrome P450BM3 with the assistance of amino acid derivatives as decoy molecules. The catalytic turnover rate and the total turnover number reached 259 min−1 P450BM3−1 and 40 200 P450BM3−1 when N‐heptyl‐l‐proline modified with l‐phenylalanine (C7‐l‐Pro‐l‐Phe) was
细胞色素P450BM3借助氨基酸衍生物作为诱饵分子,催化苯选择性羟基化为苯酚,而不会形成因过氧化而形成的副产物。催化周转率和总成交额数达到259分钟-1 P450BM3 -1和40 200 P450BM3 -1当N庚基升改性脯氨酸与升-苯丙氨酸(C7-升-Pro-升‐Phe)被用作诱饵分子。这项工作表明,具有与脂肪酸完全不同的结构的氨基酸衍生物可用作野生型P450BM3进行芳香族羟基化的诱饵分子。这种通过野生型P450BM3进行非天然底物羟基化的方法具有扩大P450BM3用于生物转化的效用的潜力。
