Characterization of a Thermophilic ATP-Dependent DNA Ligase from the Euryarchaeon Pyrococcus horikoshii [PDF]
ABSTRACT Archaea encode a DNA ligase composed of a C-terminal catalytic domain typical of ATP-dependent ligases plus an N-terminal domain similar to that found in eukaryotic cellular and poxvirus DNA ligases. All archaeal DNA ligases characterized to date have ATP-dependent adenylyltransferase and nick-joining activities. However,

ATPase-dependent control of the Mms21 SUMO ligase during DNA repair.
Modification of proteins by SUMO is essential for the maintenance of genome integrity. During DNA replication, the Mms21-branch of the SUMO pathway counteracts recombination intermediates at damaged replication forks, thus facilitating sister chromatid ...

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 ...

A Primer-dependent Polymerase Function of Pseudomonas aeruginosa ATP-dependent DNA Ligase (LigD) [PDF]
Pseudomonas aeruginosa encodes two putative DNA ligases: a classical NAD(+)-dependent DNA ligase (LigA) plus an ATP-dependent DNA ligase (LigD). LigD exemplifies a family of bacterial proteins that consist of a ligase domain fused to flanking domains that resemble nucleases and/or polymerases. Here we purify LigD and show that it possesses an intrinsic

The eukaryotic Pso2/Snm1/Artemis proteins and their function as genomic and cellular caretakers
DNA double-strand breaks (DSBs) represent a major threat to the genomic stability of eukaryotic cells. DNA repair mechanisms such as non-homologous end joining (NHEJ) are responsible for the maintenance of eukaryotic genomes.
