In Bacteria, the replicative DNA ligase is NAD‐dependent. However, some bacteria possess accessory ATP‐dependent DNA ligases (ADLs) which vary in size and domain organization. Phylogenomic analyses of bacterial ADLs reveal that types Lig B, Lig C and Lig D have descended from a common ancestor, while Lig E was transferred in a separate event, possibly from a bacteriophage. For details, see the article by Williamson et al. on pp. 274‐290 of this issue. [PDF]

Molecular Microbiology, 2015 SummaryPrior to the discovery of a minimal ATP‐dependent DNA ligase in Haemophilus influenzae, bacteria were thought to only possess a NAD‐dependent ligase, which was involved in sealing of Okazaki fragments. We now know that a diverse range of bacterial species possess up to six of these accessory bacterial ATP‐dependent DNA ligases (b‐ADLs), which ...

Characterization of an ATP-dependent DNA ligase encoded by Chlorella virus PBCV-1 [PDF]
Journal of Virology, 1997 We report that Chlorella virus PBCV-1 encodes a 298-amino-acid ATP-dependent DNA ligase. The PBCV-1 enzyme is the smallest member of the covalent nucleotidyl transferase superfamily, which includes the ATP-dependent polynucleotide ligases and the GTP-dependent RNA capping enzymes.

ATP-dependent DNA ligase fromThermococcussp. 1519 displays a new arrangement of the OB-fold domain [PDF]
Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2012 DNA ligases join single-strand breaks in double-stranded DNA by catalyzing the formation of a phosphodiester bond between adjacent 5'-phosphate and 3'-hydroxyl termini. Their function is essential for maintaining genome integrity in the replication, recombination and repair of DNA. High flexibility is important for the function of DNA ligase molecules.

Bleomycin-induced DNA repair by Saccharomyces cerevisiae ATP-dependent polydeoxyribonucleotide ligase [PDF]
Journal of Bacteriology, 1988 In contrast to ligase-deficient (cdc9) Saccharomyces cerevisiae, which did not rejoin bleomycin-induced DNA breaks, ligase-proficient (CDC9) yeast cells eliminated approximately 90% of DNA breaks within 90 to 120 min after treatment. Experimental conditions restricted enzymatic removal of the unusual 3'-phosphoglycolate termini in DNA cleaved by ...

Identification of Novel Inhibitors of Escherichia coli DNA Ligase (LigA)
Molecules, 2021 Present in all organisms, DNA ligases catalyse the formation of a phosphodiester bond between a 3′ hydroxyl and a 5′ phosphate, a reaction that is essential for maintaining genome integrity during replication and repair.

The minimal Bacillus subtilis nonhomologous end joining repair machinery. [PDF]
PLoS ONE, 2013 It is widely accepted that repair of double-strand breaks in bacteria that either sporulate or that undergo extended periods of stationary phase relies not only on homologous recombination but also on a minimal nonhomologous end joining (NHEJ) system ...
