2.7.7.7 | deoxynucleoside triphosphate + DNAn | DNA polymerase IV (Dpo4) shows 90-fold higher incorporation efficiency of dCTP > dATP opposite 8-oxoG and 4-fold higher efficiency of extension beyond an 8-oxoG:C pair than an 8-oxoG:A pair. The catalytic efficiency for these events (with dCTP or C) is similar for G and 8-oxoG templates. Extension beyond an 8-oxoG:C pair is similar to G:C and faster than for an 8-oxoG:A pair, in contrast to other polymerases. dCTP insertion opposite 8-oxoG was lower than for opposite guanine | Saccharolobus solfataricus | diphosphate + DNAn+1 | - |

2.7.7.7 | deoxynucleoside triphosphate + DNAn | when insertion is opposite an unmodified G, insertion of dATP or dGTP is 1000 less efficient than dCTP. For insertion opposite 8-oxoG, the order of decreasing efficiency is dCTP, dATP, dGTP, with an order of magnitude or more difference in catalytic efficiency (kcat/Km) in each pair of comparisons. The insertion of dCTP opposite G and 8-oxoG shows similar catalytic efficiency, even with differences in the trends for kcat and Km. 90fold higher incorporation efficiency of dCTP compared to dATP opposite 8-oxoG and 4fold higher efficiency of extension beyond an 8-oxoG:C pair than an 8-oxoG:A pair. The catalytic efficiency for these events (with dCTP or C) is similar for G and 8-oxoG templates. The 8-oxoG:C pair shows classic Watson-Crick geometry; the 8-oxoG:A pair is in the syn:anti configuration, with the A hybridized in a Hoogsteen pair with 8-oxoG. With dGTP placed opposite 8-oxoG, pairing was not to the 8-oxoG but to the 5'C (and in classic Watson-Crick geometry), consistent with the low frequency of this frameshiftevent observed in the catalytic assays | Saccharolobus solfataricus | diphosphate + DNAn+1 | - |
