β-Difluoromethylene deoxynucleoside 5′-triphosphates (dNTPs, N = A or C) are advantageously obtained via phosphorylation of corresponding dNDP analogues using catalytic ATP, PEP, nucleoside diphosphate kinase, and pyruvate kinase. DNA pol β Kd values for the α,β-CF2 and unmodified dNTPs, α,β-NH dUTP, and the α,β-CH2 analogues of dATP and dGTP are discussed in relation to the conformations of α,β-CF2 dTTP versus
α,β-二氟亚甲基脱氧核苷 5'-三磷酸(dNTP,N = A 或 C)有利地通过使用催化 ATP、PEP、核苷二磷酸激酶和丙酮酸激酶对相应的 dNDP 类似物进行磷酸化获得。α,β-CF 2和未修饰的 dNTP、α,β-NH dUTP 以及dATP 和 dGTP的 α,β-CH 2类似物的DNA pol β K d值与 α,β-的构象有关CF 2 dTTP 与结合到酶活性位点的 α,β-NH dUTP。
