multifluorinated DNApolymerase with all 14 methionine residues (Met; red in the structure) globally replaced by the non‐natural amino acid trifluoromethionine (TFM) exhibits enzymatic activity and selectivity similar to the wild type. The fluorinated enzyme serves as a 19F NMR probe, and despite its size of 63 kDa, individual 19F resonances allow the study of enzyme dynamics during DNA synthesis by NMR
一种全氟化的DNA聚合酶,其全部14个蛋氨酸残基(蛋氨酸;结构中的红色)被非天然氨基酸三氟蛋氨酸(TFM)全局取代,表现出与野生型相似的酶促活性和选择性。氟化酶用作19 F NMR探针,尽管其大小为63 kDa,但单独的19 F共振允许通过NMR光谱研究DNA合成过程中的酶动力学。
