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 ...

Molecular Microbiology, 2001 DNA ligases join breaks in the phosphodiester backbone of DNA molecules and are used in many essential reactions within the cell. All DNA ligases follow the same reaction mechanism, but they may use either ATP or NAD+ as a cofactor. All Bacteria (eubacteria) contain NAD+‐dependent DNA ligases, and the uniqueness of these enzymes to Bacteria makes them ...

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 ...

Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA
Frontiers in Plant Science, 2021 Protein modification by the small ubiquitin-like modifier (SUMO) plays an important role in multiple plant processes, including growth, development, and the response to abiotic stresses.

DNA ligases as therapeutic targets. [PDF]
Transl Cancer Res, 2013 During DNA replication, DNA joining events link Okazaki fragments on the lagging strand. In addition, they are required to repair DNA single- and double-strand breaks and to complete repair events initiated by the excision of mismatched and damaged bases.

Structure and function of the DNA ligases encoded by the mammalian LIG3 gene. [PDF]
Gene, 2013 Among the mammalian genes encoding DNA ligases (LIG), the LIG3 gene is unique in that it encodes multiple DNA ligase polypeptides with different cellular functions.

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 to impaired but not ablated activity.

E3 ubiquitin ligases: structural diversity, dysregulation in disease, and their emerging role in targeted therapeutic strategies [PDF]
Frontiers in Molecular BiosciencesThe Ubiquitin-Proteasome System (UPS) is a key mechanism of cellular homeostasis. A central part of this mechanism is E3 ubiquitin ligases, which selectively direct proteins to be ubiquitinated for degradation via the UPS.
