title: 2'-Fluoro-2'-deoxycytidine triphosphate as a substrate for RNA- and DNA-dependent DNA polymerases.
abstract: The ability of the analog 2'-fluoro-2'-deoxycytidine triphosphate (dCflTP) to be used as a substrate in the reactions catalyzed by Xenopus laevis oocytes DNA polymerase alpha and AMV reverse transcriptase has been studied. The apparent Km values for dCTP and dCflTP, using activated DNA as templates, were 0.6 microM and 7 mM with DNA polymerase alpha and 0.14 microM and 7 microM with AMV reverse transcriptase, respectively. As observed with dCTP, aphidicolin was a noncompetitive inhibitor in the DNA polymerase alpha-catalyzed DNA synthesis; the Ki values were about 2 microM for both substrates. dCflTP can also be incorporated into DNA synthetized by other eukaryotic DNA polymerases and by reverse transcriptase with RNA as a template, both in the presence or absence of (dT)12 primer.
