  Base Pairing and Replicative Processing of the Formamidopyrimidine-dG DNA Lesion

  摘要：

  The 2,6-diamino-4-hydroxy-5-formamidopyrimidine of 2'-deoxyguanosine (FaPydG) is one of the major DNA lesions found after oxidative stress in cells. To clarify the base pairing and coding potential of this major DNA lesion with the aim to estimate its mutagenic effect, we prepared oligonucleotides containing a cyclopentane based analogue of the DNA lesion (cFaPydG). In addition, oligonucleoticles containing the cyclopentane analogue of 2'-deoxyguanosine (cdG), and oligonucleotides containing 8-oxo-7,8-dihydro2'-deoxyguanosine (8-oxodG) were synthesized. The thermodynamic stability of duplexes containing these building blocks and all canonical counterbases were determined by concentration dependent melting-point measurements (van't Hoff plots). The data reveal that cFaPydG greatly destabilizes a DNA duplex (Delta Delta G(o)298K approximate to 2-4 kcal mol(-1)). The optimal base pairing partner for the cFaPydG lesion is dC. Investigation of duplexes containing dG and cdG shows that the effect of substituting the deoxyribose by a cyclopentane moiety is marginal. The data also provide strong evidence that the FaPydG lesion is unable to form a base pair with dA. Our computational studies indicate that the syn-conformation required for base pairing with dA is energetically unfavorable. This is in contrast to 8-oxodG for which the syn-conformation represents the energetic minimum. Kinetic primer extension studies using S. cerevisiae Pol eta reveal that cFaPydG is replicated in an error-free fashion. dC is inserted 2-3 orders of magnitude more efficiently than dT or CIA, showing that FaPydG is a lesion which retains the coding potential of dG. This is also in contrast to 8-oxodG, for which base pairing with dC and dA was established.
