with template guanine and Watson-Crick paired dCTP as the nascent base pair. Water-mediated and substrate-assisted mechanism: the initial proton transfer to the R-phosphate of the substrate via a bridging crystal water molecule is the rate-limiting step, the nucleotidyl-transfer step is associative with a metastable pentacovalent phosphorane intermediate, and the diphosphate leaving is facilitated by a highly coordinated proton relay mechanism through mediation of water which neutralizes the evolving negative charge. The conserved carboxylates, which retain their liganding to the two Mg2+ ions during the reaction process, are found to be essential in stabilizing transition states. This water-mediated and substrate-assisted mechanism takes specific advantage of the unique structural features of this low-fidelity lesion-bypass Y-family polymerase, which has a more spacious and solvent-exposed active site than replicative and repair polymerases

deamination of cytosine to uracil is a hydrolytic reaction that is greatly accelerated at high temperatures. The resulting uracil pairs with adenine during DNA replication, thereby inducing G:C to A:T transitions in the progeny. B-family DNA polymerases from hyperthermophilic archaea recognize the presence of uracil in DNA and stall DNA synthesis. Although PolB1 per se specifically binds to uracil-containing single-stranded DNA, the binding efficiency is substantially enhanced by the initiation of DNA synthesis. The generation of ds DNA is significantly inhibited, however, by the presence of template uracil. Pol B1 more efficiently recognizes uracil in DNA during DNA synthesis rather than during random diffusion in solution. Single molecules of Pol B1 bind to template uracil and stall DNA synthesis

an abasic lesion causes Dpo4 to switch from a normal to a very mutagenic mode of replication. Incorporation upstream of the abasic lesion is replicated error-free. Once Dpo4 encounters the lesion, synthesis became sloppy, with bypass products containing a myriad of mutagenic events. Incorporation of dAMP (29%) and dCMP (53%) opposite the abasic lesion at 37°C correlates exceptionally well with our kinetic results and demonstrates two dominant bypass pathways via the A-rule and the lesion loop-out mechanism. The percentage of overall frameshift mutations increases from 71% (37°C) to 87% (75°C)

ATP binding to replication factor C is sufficient for loading the heterotrimeric PCNA123 [proliferating cell nuclear antigen (PCNA)] clamp onto DNA that includes a rate-limiting conformational rearrangement of the complex. ATP hydrolysis is required for favorable recruitment and interactions with the replication polymerase (PolB1) that most likely include clamp closing and dissociation of replication factor C. Surprisingly, the assembled holoenzyme complex synthesizes DNA distributively and with low processivity, unlike most other well-characterized DNA polymerase holoenzyme complexes. PolB1 repeatedly disengages from the DNA template, leaving PCNA123 behind. Interactions with a C-terminal PCNA-interacting peptide (PIP) motif on PolB1 specifically with PCNA2 are required for holoenzyme formation and continuous re-recruitment during synthesis

Replication of the C8-adduct at the G3-position results in two-base deletion, whereas error-free bypass and extension is observed at the G1-position. The N2-adduct is bypassed and extended when positioned at the G1-position, and the error-free product is observed. The N2-adduct at the G3-position is more blocking and is bypassed and extended only by Dpo4 to produce an errorfree product. The replication of the 2-amino-3-methylimidazo[4,5-f]quinoline-adducts of dGuo is strongly influenced by the local sequence and the regioisomer of the adduct

Based on the efficiency ratios, Dpo4 selects nucleotides for blunt-end addition in the order of decreasing efficiency: dATP, dTTP, dCTP, dGTP, with dATP favored by five to 50fold over the other nucleotides. The first bluntend dATP incorporation is 80fold more efficient than the second, and among natural deoxynucleotides, dATP is the preferred substrate due to its stronger intrahelical base-stacking ability

proliferating cell nuclear antigen facilitates DNA synthesis with Dpo3, as with Dpo1 and Dpo4, but very weakly with Dpo2. DNA synthesis in the presence of proliferating cell nuclear antigen, replication factor C, and single-stranded binding protein is most processive with DNA polymerase Dpo1 in comparison to DNA polymerase Dpo3 and Dpo4. DNA lesion bypass DNA synthesis in the presence of proliferating cell nuclear antigen, replication factor C, and single-stranded binding protein is most effective with DNA polymerase Dpo4 in comparison to DNA polymerase Dpo1 and Dpo3. Both Dpo2 and Dpo3, but not Dpo1, bypass hypoxanthine and 8-oxoguanine. Dpo2 and Dpo3 bypass uracil and cis-syn cyclobutane thymine dimer, respectively.

the enzyme does not efficiently insert nucleotides opposite to the (6S,8R,11S)-1,N2-deoxyguanosine adduct, consistent with the low levels of Gua->Thy mutations. However it extends past the (6S,8R,11S)-1,N2-deoxyguanosine:dCyd pair. A series of ternary (Dpo4-DNA-dNTP) structures with (6S,8R,11S)-1,N2-deoxyguanosine-adducted templates suggest that during replication, the ring-closed (6S,8R,11S)-1,N2-deoxyguanosine lesion at the active site hinders incorporation of dNTPs opposite the lesion, whereas the ring-opened form of the lesion in the (6S,8R,11S)-1,N2-deoxyguanosine:dCyd pair allows for extension to full-length product

the enzyme possess a remarkable DNA stabilizing ability for maintaining weak base pairing interactions to facilitate primer extension. This thermal stabilization by Dpo1 allows for template-directed synthesis at temperatures more than 30°C above the melting temperature of naked DNA. Dpo1 elongates single stranded DNA in template-dependent and template-independent manners. Initial deoxyribonucleotide incorporation is complementary to the template. Rate-limiting steps that include looping back and annealing to the template allow for a unique template-dependent terminal transferase activity.

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

the molecular dynamics simulations suggest that mismatched nucleotide insertion opposite 10S-(+)-trans-anti-[benzo[a]pyrene]-N2-dG is increased at 55°C compared with 37°C because the higher temperature shifts the preference of the damaged base from the anti to the syn conformation, with the carcinogen on the more open major groove side. The mismatched dNTP structures are less distorted when the damaged base is syn than when it is anti, at the higher temperature. With the normal partner dCTP, the anti conformation with close to Watson-Crick alignment remains more favorable. The molecular dynamics simulations are consistent with the kcat values for nucleotide incorporation opposite the lesion studied, providing structural interpretation of the experimental observations. The observed temperature effect suggests that conformational flexibility plays a role in nucleotide incorporation and bypass fidelity opposite 10S-(+)-trans-anti-[benzo[a]pyrene]-N2-dG by Dpo4

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

kinetic study of dNTP primer-extension opposite a benzo[a]pyrene-N2-dG-adduct with four DNA polymerases, including Sulfolobus solfataricus Dpo4 and Sulfolobus acidocaldarius Dbh. Vmax/Km is similar for correct dCTP insertion with Dpo4 and Dbh. Compared to Dpo4, Dbh misinsertion is slower for dATP (about 20fold), dGTP (about 110fold) and dTTP (about 6fold), due to decreases in Vmax. These findings provide support that Dbh is in the same Y-Family DNA polymerase class as eukaryotic DNA polymerase kappa and bacterial DNA polymerase IV, which accurately bypass N2-dG adducts

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

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
