Mechanistic Studies with DNA Polymerases Reveal Complex Outcomes following Bypass of DNA Damage
DNA is a chemically reactive molecule that is subject to many different covalent modifications from sources that are both endogenous and exogenous in origin. The inherent instability of DNA is a major obstacle to genomic maintenance and contributes in varying degrees to cellular dysfunction and disease in multi-cellular organisms. Investigations into the chemical and biological aspects of DNA d...
متن کاملDNA polymerases: mechanistic insight from biochemical and biophysical studies.
In vivo the DNA polymerases are responsible for replicative and repair DNA synthesis. These enzymes use the pre-existing 3'-OH group of a primer annealed to a single-stranded DNA template to incorporate monophosphate deoxynucleosides (dNMPs) in a sequential and directional manner. Although all DNA polymerases share a similar catalytic core constituted by a palm, a thumb and a fingers domain and...
متن کاملStructural and mechanistic studies of polymerase η bypass of phenanthriplatin DNA damage.
Platinum drugs are a mainstay of anticancer chemotherapy. Nevertheless, tumors often display inherent or acquired resistance to platinum-based treatments, prompting the search for new compounds that do not exhibit cross-resistance with current therapies. Phenanthriplatin, cis-diamminephenanthridinechloroplatinum(II), is a potent monofunctional platinum complex that displays a spectrum of activi...
متن کاملEvidence for lesion bypass by yeast replicative DNA polymerases during DNA damage
The enzyme ribonucleotide reductase, responsible for the synthesis of deoxyribonucleotides (dNTP), is upregulated in response to DNA damage in all organisms. In Saccharomyces cerevisiae, dNTP concentration increases approximately 6- to 8-fold in response to DNA damage. This concentration increase is associated with improved tolerance of DNA damage, suggesting that translesion DNA synthesis is m...
متن کاملLesion bypass DNA polymerases replicate across non-DNA segments.
A critical feature of the robustness of the DNA replication machinery is the ability to complete its task in the presence of interfering DNA damage. A key mechanism responsible for this task is translesion replication (also termed translesion synthesis), carried out by specialized lesion bypass DNA polymerases of the Y superfamily. Here we show that in Escherichia coli, plasmids can be replicat...
