以5 '-氯-5'-脱氧腺苷(5 '-ClDA)类似物为底物,以FlA 1活性位点突变体为探针,研究FlA 1氟化酶特异性的分子决定簇。在F213或A279残基处的修饰对这些修饰的底物是有益的,包括5 '-氯-5'-脱氧-2-乙炔基腺苷,ClDEA(>10倍活性改善),并且赋予对不容易被野生型FlAl接受的底物的新活性。
Molecular determinants of FlA1 fluorinase specificity were probed using 5'-chloro-5'-deoxyadenosine (5'-ClDA) analogs as substrates and FlA1 active site mutants. Modifications at F213 or A279 residues are beneficial towards these modified substrates, including 5'-chloro-5'-deoxy-2-ethynyladenosine, ClDEA (>10-fold activity improvement), and conferred novel activity towards substrates not readily accepted by wild-type FlA1.
