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 ...

Plant SUMO E3 Ligases: Function, Structural Organization, and Connection With DNA
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 Ligase I, the Replicative DNA Ligase [PDF]
Multiple DNA ligation events are required to join the Okazaki fragments generated during lagging strand DNA synthesis. In eukaryotes, this is primarily carried out by members of the DNA ligase I family. The C-terminal catalytic region of these enzymes is composed of three domains: a DNA binding domain, an adenylation domain and an OB-fold domain.

Detection of ligation products of DNA linkers with 5'-OH ends by denaturing PAGE silver stain. [PDF]
To explore if DNA linkers with 5'-hydroxyl (OH) ends could be joined by commercial T4 and E. coli DNA ligase, these linkers were synthesized by using the solid-phase phosphoramidite method and joined by using commercial T4 and E. coli DNA ligases.

Inactivating UBE2M impacts the DNA damage response and genome integrity involving multiple cullin ligases. [PDF]
Protein neddylation is involved in a wide variety of cellular processes. Here we show that the DNA damage response is perturbed in cells inactivated with an E2 Nedd8 conjugating enzyme UBE2M, measured by RAD51 foci formation kinetics and cell based DNA ...

CRL Ubiquitin Ligases and DNA Damage Response
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 ...

Novel E3 ubiquitin ligases that regulate histone protein levels in the budding yeast Saccharomyces cerevisiae. [PDF]
Core histone proteins are essential for packaging the genomic DNA into chromatin in all eukaryotes. Since multiple genes encode these histone proteins, there is potential for generating more histones than what is required for chromatin assembly.

Targeted Degradation of 53BP1 Using Ubiquitin Variant Induced Proximity
In recent years, researchers have leveraged the ubiquitin-proteasome system (UPS) to induce selective degradation of proteins by E3 ubiquitin ligases, which has great potential as novel therapeutics for human diseases, including cancer and ...
