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 ...

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 ...

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.

DNA binding with a minimal scaffold: structure–function analysis of Lig E DNA ligases [PDF]
Nucleic Acids Research, 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.

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

DNA ligases in the repair and replication of DNA
Mutation Research DNA Repair, 2000 DNA ligases are critical enzymes of DNA metabolism. The reaction they catalyse (the joining of nicked DNA) is required in DNA replication and in DNA repair pathways that require the re-synthesis of DNA.

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 ...

CRL Ubiquitin Ligases and DNA Damage Response [PDF]
Frontiers in Oncology, 2012 Cullin/RING ubiquitin ligases (CRL) comprise the largest subfamily of ubiquitin ligases and are involved in various biological processes. One of the main functions of CRLs is to regulate DNA damage response, a fundamental signaling cascade to maintain ...
