Translesion DNA Synthesis
Human DNA polymerase η (pol η) is the gene product that is altered in the variant form of xeroderma pigmentosum. Pol η has a structure that can accommodate the cyclobutane pyrimidine dimer, the most prominent ultraviolet-induced DNA lesion. Pol η catalyzes efficient and accurate translesion DNA synthesis (TLS) under the fine control of systems involving interactions with mono-ubiquitinated

 · Tobacco-derived pyridyloxobutyl (POB) DNA adducts are unique due to the large size and flexibility of the alkyl chain connecting the pyridyl ring to the nucleobase. Recent experimental work suggests that the O4-4-(3-pyridyl)-4-oxobut-1-yl-T (O4-POB-T) lesion can undergo both nonmutagenic (dATP) and mutagenic (dGTP) insertion by the translesion synthesis (TLS) polymerase (pol) η in …

ADN polymérase — Wikipédia

Une ADN polymérase est un complexe enzymatique intervenant dans la réplication de l’ADN au cours du cycle cellulaire, mais aussi dans des processus de réparation et de recombinaison de l’ADN. Les ADN polymérases utilisent des désoxyribonucléosides triphosphate comme base pour la synthèse d’un brin d’ADN, en utilisant un autre brin d’ADN comme matrice.

 · However, these translesion polymerases are not processive and they are poorly accurate. Therefore, they need to be tightly regulated. This is achieved by the covalent binding of the small ubiquitin peptide to the polymerase cofactor PCNA that subsequently

DNA polymerases are co-ordinated by sliding clamps (PCNA/beta-clamp) in translesion synthesis. It is unclear how these enzymes assemble on PCNA with geometric and functional compatibility. We report the crystal structure of a full-length Y-family polymerase
