Upon treatment of rats with a hepatocarcinogen, N-2-fluorenylacetamide, the TdT-like activity increased in parallel with DNA polymerase α and γ. By phosphocellulose column chromatography, the TdT-like activity was separated from DNA polymerase α, β, and γ. With a poly(dA)-initiator, dGTP or dCTP was the most efficient substrate in the presence of Mg^2+ or Mn^2+, respectively. In the presence of Mg^2+, the enzyme utilized poly (dC) as an initiator most efficiently. The TdT-like activity differed from previously described terminal deoxynucleotidyl transferase (E.C.2.7.7.31.) in its Km value for dGTP and in its sensitivity to ATP or to an antibody against calf thymus terminal deoxynucleotidyl transferase.}, pages = {43--49}, title = {Occurrence of a Terminal Deoxynucleotidyl Transferase-Like Activity in N-2-Fluorenylacetamide-treated Rat Liver}, volume = {47}, year = {1985} }
