1 The DNA pol kappa was maximally activated to similar levels by a twenty-fold lower concentration of Mn(2+) compared to Mg(2+). Manganese(2+) DNA polymerase lambda Homo sapiens
2 Strikingly, Mn(2+) activation of DNA pol kappa resulted in a dramatically lower efficiency of correct nucleotide incorporation opposite both N(2)-ethyl-Gua and Gua compared to that detected upon Mg(2+) activation. Manganese(2+) DNA polymerase lambda Homo sapiens
3 A rapid kinetic analysis showed diminished burst amplitudes in the presence of Mn(2+) compared to Mg(2+) indicating that DNA pol kappa preferentially utilizes Mg(2+) activation. Manganese(2+) DNA polymerase lambda Homo sapiens
