Learn the definition of DNA ligase and explore the role of DNA ligase in DNA synthesis and repair, as well as its current uses in molecular...
In the mechanism of DNA ligase, two covalent phosphodiester bonds between the 3’ hydroxyl end of acceptor nucleotide with the 5’ phosphate end of donor nucleotide are formed. In this process, two ATP molecules are consumed per one phosphodiester bond. The reaction can proceed in three steps o...

in a manner that requires either adenosine triphosphate (ATP) or NAD+. DNAligasesare hugely important inmolecular biologyand biotechnology, particularly for their role in gene cloning. They play essential roles inDNA replicationand repair processes, and defects inDNA ligaseactivity in humans can lead...
PURPOSE:To obtain DNA ligase having high heat resistance and a wide range of proper temperature of action, by extracting it from a mold of Thermus thermophilus, purifying it. CONSTITUTION:DNA ligase having the following physical and chemical properties is obtained from a mold of Thermus thermophilus...
DNA ligase was partially purified from normal and regenerating rat liver. Its structure was studied using the activity gel procedure that identifies the functional polypeptides. Two slightly different purification procedures were followed, leading to the isolation of one or two peaks (fractions A and ...
High fidelity DNA ligation prevents single base insertions in the yeast genome DNA ligase 1 finalizes nuclear DNA replication by accurately sealing nicks generated during Okazaki Fragment Maturation. Here, Williams et al employ a low fidelity DNA ligase 1 variant to study mutation rates and specificity...
l DNA polymerase: after the RNA primer is removed, a notch is left in the DNA, that is, the natural PTJ, which extends through the polymerase until it is adjacent to the end of the previous Okazaki fragment. l DNA ligase: under the action of ATP, DNA ligase forms a phosphodiester bond...
