deoxynucleoside triphosphate + DNAn | the fidelity of Dpo4 is in the range of 0.001-0.0001. The ground-state binding affinity of correct nucleotides is 10-50-fold weaker than those of replicative DNA polymerases. The affinity of incorrect nucleotides for Dpo4 is about 2-10-fold weaker than that of correct nucleotides. The mismatched dCTP has an affinity similar to that of the matched nucleotides when it is incorporated against a pyrimidine template base flanked by a 5'-template guanine. The mismatch incorporation rates, regardless of the 5'-template base, are about 2-3 orders of magnitude slower than the incorporation rates for matched nucleotides, which is the predominant contribution to the fidelity of Dpo4 | Saccharolobus solfataricus | diphosphate + DNAn+1 | - |
