Structure of the error-prone DNA ligase of African swine fever virus identifies critical active site residues

Nature Communications, 2019
African swine fever virus (ASFV) is contagious and can cause highly lethal disease in pigs. ASFV DNA ligase (AsfvLIG) is one of the most error-prone ligases identified to date; it catalyzes DNA joining reaction during DNA repair process of ASFV and plays

DNA ligase 1 deficient plants display severe growth defects and delayed repair of both DNA single and double strand breaks

BMC Plant Biology, 2009
Background DNA ligase enzymes catalyse the joining of adjacent polynucleotides and as such play important roles in DNA replication and repair pathways. Eukaryotes possess multiple DNA ligases with distinct roles in DNA metabolism, with clear differences ...

PARP-3 and APLF function together to accelerate nonhomologous end joining [PDF]

, 2010
PARP-3 is a member of the ADP-ribosyl transferase superfamily of unknown function. We show that PARP-3 is stimulated by DNA double-strand breaks (DSBs) in vitro and functions in the same pathway as the poly (ADP-ribose)-binding protein APLF to accelerate

Mammalian DNA ligases. Catalytic domain and size of DNA ligase I. [PDF]

Journal of Biological Chemistry, 1990
DNA ligase I is the major DNA ligase activity in proliferating mammalian cells. The protein has been purified to apparent homogeneity from calf thymus. It has a monomeric structure and a blocked N-terminal residue. DNA ligase I is a 125-kDa polypeptide as estimated by sodium dodecyl sulfate-gel electrophoresis and by gel chromatography under denaturing

T4 DNA ligase structure reveals a prototypical ATP-dependent ligase with a unique mode of sliding clamp interaction

Nucleic Acids Research, 2018
DNA ligases play essential roles in DNA replication and repair. Bacteriophage T4 DNA ligase is the first ATP-dependent ligase enzyme to be discovered and is widely used in molecular biology, but its structure remained unknown. Our crystal structure of T4

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]

, 2003
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

Altered DNA ligase activity in human disease.

Mutagenesis, 2019
The joining of interruptions in the phosphodiester backbone of DNA is critical to maintain genome stability. These breaks, which are generated as part of normal DNA transactions, such as DNA replication, V(D)J recombination and meiotic recombination as ...

Temperature dependence of circular DNA topological states [PDF]

PHYSICAL REVIEW E 79, 041926 (2009), 2009
Circular double stranded DNA has different topological states which are defined by their linking numbers. Equilibrium distribution of linking numbers can be obtained by closing a linear DNA into a circle by ligase. Using Monte Carlo simulation, we predict the temperature dependence of the linking number distribution of small circular DNAs.

Evaluation of NAD(+)-dependent DNA ligase of mycobacteria as a potential target for antibiotics [PDF]

, 2007
Mycobacteria contain genes for several DNA ligases, including ligA, which encodes a NAD+-dependent enzyme that has been postulated to be a target for novel antibacterial compounds.

Detection of ligation products of DNA linkers with 5'-OH ends by denaturing PAGE silver stain. [PDF]

PLoS ONE, 2012
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.
