The E. coli DNA ligase is encoded by the lig gene. DNA ligase in E. coli, as well as most prokaryotes, uses energy gained by cleaving nicotinamide adenine dinucleotide (NAD) to create the phosphodiester bond. It does not ligate blunt-ended DNA except under conditions of molecular crowding with polyethylene glycol, and cannot join RNA to DNA efficiently. The activity of E. coli DNA ligase can be enhanced by DNA polymerase at the right concentration… WebTimson et al., 2000). NHEJ is the principal mechanism by which mammalian cells repair DNA double-strand breaks (DSBs) caused by exposure to ionizing radiation or certain classesofchemical mutagens.In the NHEJ pathway, broken DNA ends are rejoined, a process requiring the Ku proteins and DNA ligase IV (Jeggo, 1998). Mice lacking DNA …
