Eukaryotic DNA ligases seal DNA breaks in the final step of DNA replication and repair transactions via a three-step reaction mechanism that can abort if DNA ligases encounter modified DNA termini, such as the products and repair intermediates of DNA oxidation, alkylation, or the aberrant incorporation of ribonucleotides into genomic DNA. Such abortive DNA ligation reactions act as molecular checkpoint for DNA damage and create 5'-adenylated nucleic acid termini in the context of DNA and RNA-DNA ...[more]
