Mammalian DNA ligases. Biosynthesis and intracellular localization of DNA ligase I.
Journal of Biological Chemistry, 1990 Mammalian DNA ligase I is presumed to act in DNA replication. Rabbit antibodies against the homogeneous enzyme from calf thymus inhibited DNA ligase I activity and consistently recognized a single polypeptide of 125 kDa when cells from an established bovine kidney cell line (MDBK) were lysed rapidly by a variety of procedures and subjected to ...

The Sole DNA Ligase in Entamoeba histolytica Is a High-Fidelity DNA Ligase Involved in DNA Damage Repair [PDF]
Frontiers in Cellular and Infection Microbiology, 2018 The protozoan parasite Entamoeba histolytica is exposed to reactive oxygen and nitric oxide species that have the potential to damage its genome. E. histolytica harbors enzymes involved in DNA repair pathways like Base and Nucleotide Excision Repair. The majority of DNA repairs pathways converge in their final step in which a DNA ligase seals the DNA ...

The COP9 SIGNALOSOME is required for postembryonic meristem maintenance in Arabidopsis thaliana [PDF]
, 2015 Cullin-RING E3 ligases (CRLs) regulate different aspects of plant development, and are activated by modification of their cullin subunit with the ubiquitin-like protein NEDD8 (NEural precursor cell expressed Developmentally Down-regulated 8) (neddylation)

DNA ligase IV syndrome; a review [PDF]
Orphanet Journal of Rare Diseases, 2016 DNA ligase IV deficiency is a rare primary immunodeficiency, LIG4 syndrome, often associated with other systemic features. DNA ligase IV is part of the non-homologous end joining mechanism, required to repair DNA double stranded breaks. Ubiquitously expressed, it is required to prevent mutagenesis and apoptosis, which can result from DNA double strand ...

Effects of DNA-binding drugs on T4 DNA ligase [PDF]
Biochemical Journal, 1990 A number of DNA intercalating and externally binding drugs have been found to inhibit nick sealing, cohesive and blunt end ligation, AMP-dependent DNA topoisomerization and EDTA-induced DNA nicking mediated by bacteriophage T4 DNA ligase. The inhibition seems to arise from drug-substrate interaction so that formation of active DNA-Mg2(+)-AMP-enzyme ...

Tankyrases Promote Homologous Recombination and Check Point Activation in Response to DSBs. [PDF]
PLoS Genetics, 2016 DNA lesions are sensed by a network of proteins that trigger the DNA damage response (DDR), a signaling cascade that acts to delay cell cycle progression and initiate DNA repair.
