Comparative analysis of the end-joining activity of several DNA ligases. [PDF]
PLoS ONE, 2017 DNA ligases catalyze the repair of phosphate backbone breaks in DNA, acting with highest activity on breaks in one strand of duplex DNA. Some DNA ligases have also been observed to ligate two DNA fragments with short complementary overhangs or blunt ...

Extraordinarily Stable Hairpin-Based Biosensors for Rapid Detection of DNA Ligases [PDF]
Biosensors, 2023 DNA ligases are essential enzymes involved in DNA replication and repair processes in all organisms. These enzymes seal DNA breaks by catalyzing the formation of phosphodiester bonds between juxtaposed 5′ phosphate and 3′ hydroxyl termini in double ...

Bacteriophage origin of some minimal ATP-dependent DNA ligases: a new structure from Burkholderia pseudomallei with striking similarity to Chlorella virus ligase [PDF]
Scientific Reports, 2021 DNA ligases, the enzymes responsible for joining breaks in the phosphodiester backbone of DNA during replication and repair, vary considerably in size and structure.

Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity [PDF]
Biology Direct, 2009 Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...

Identification of a novel motif in DNA ligases exemplified by DNA ligase IV [PDF]
DNA Repair, 2006 DNA ligase IV is an essential protein that functions in DNA non-homologous end-joining, the major mechanism that rejoins DNA double-strand breaks in mammalian cells. LIG4 syndrome represents a human disorder caused by mutations in DNA ligase IV that lead

Mammalian DNA ligases; roles in maintaining genome integrity. [PDF]
J Mol Biol, 2023 The joining of breaks in the DNA phosphodiester backbone is essential for genome integrity. Breaks are generated during normal processes such as DNA replication, cytosine demethylation during differentiation, gene rearrangement in the immune system and ...

Human DNA ligases in replication and repair. [PDF]
DNA Repair (Amst), 2020 To ensure genome integrity, the joining of breaks in the phosphodiester backbone of duplex DNA is required during DNA replication and to complete the repair of almost all types of DNA damage.
