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 ...

Thermostable DNA ligases from hyperthermophiles in biotechnology [PDF]
Frontiers in Microbiology, 2023 DNA ligase is an important enzyme ubiquitous in all three kingdoms of life that can ligate DNA strands, thus playing essential roles in DNA replication, repair and recombination in vivo.

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 ...

DNA binding with a minimal scaffold: structure-function analysis of Lig E DNA ligases. [PDF]
Nucleic Acids Res, 2018 DNA ligases join breaks in the phosphodiester backbone of DNA by catalysing the formation of bonds between opposing 5′P and 3′OH ends in an adenylation-dependent manner.

Biochemical and Structural Characterisation of DNA Ligases from Bacteria and Archaea. [PDF]
Biosci Rep, 2016 DNA ligases are enzymes that seal breaks in the backbones of DNA, leading to them being essential for the survival of all organisms. DNA ligases have been studied from many different types of cells and organisms and shown to have diverse sizes and ...

Polynucleotide 3'-terminal phosphate modifications by RNA and DNA ligases. [PDF]
J Biol Chem, 2014 Background: Classic RNA ligases join 5′pRNA to RNA3′OH. Results: Thermophilic RNA ligases were able to modify ssDNA or RNA with a 3′-phosphate. Conclusion: Thermophilic ligases form RNA 2′,3′-cyclic phosphate and ssDNA3′pp5′A.

Naphthalimides Selectively Inhibit the Activity of Bacterial, Replicative DNA Ligases and Display Bactericidal Effects against Tubercle Bacilli [PDF]
Molecules, 2017 The DNA ligases, enzymes that seal breaks in the backbones of DNA, are essential for all organisms, however bacterial ligases essential for DNA replication use β-nicotinamide adenine dinucleotide as their co-factor, whereas those that are essential in ...
