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 across the yeast genome Jessica S. Williams Scott. A. Lujan Thomas A. Ku...
AP核酸内切酶(AP endonuclease):负责切割位于AP位点的DNA链,形成一个单链断裂。 DNA聚合酶β(DNA polymerase β):负责在AP位点处催化DNA链的填充,将缺失的碱基加入到DNA链中。 DNA连接酶(DNA ligase):负责连接DNA链的断裂端,使修复后的DNA链完整。 ▲碱基切除修复(BER)示意图 4)核苷酸切除修复(Nucleotide Excisio...

terminal transferase was used to add strings ofadeninesto one preparation and strings ofthymidinesto another; annealing the two populations of molecules through these poly-A and poly-T extensions; and finally treating withDNA ligase,exonuclease III, andDNA polymerase Ito covalently link and repair the...
The RNA primers are removed by another DNA polymerase, pol I, and the breaks in the sugar-phosphate backbone are sealed by DNA ligase. (b) A more realistic three-dimensional illustration.[Reproduced with permission from B. Alberts, DNA replication and recombination, Nature 421 (2003) 431–...
A small fraction (13%) of the intermediate remained even after 1 h incubation. We tested whether the Bal-31-generated nick could be repaired by T4 DNA ligase. Although T4 DNA ligase is able to ligate across a gap, it does so with very low efficiency and orders of magnitude more ...
T4 DNA ligase is used in molecular cloning experiments to ligate (join) the ends of cloned DNA fragments, Ligase is commonly to insert DNA into a cloning vector.
DNA ligase 4 (LIG4) is also present in all eukaryotes and mediates the final step in the non-homologous end joining (NHEJ) pathway of DSB repair. However, there are clear differences between eukaryotes regarding the presence of other forms of DNA ligase. Plants lack a DNA ligase III (LIG...

Prokaryotic Ligase D is a conserved DNA repair apparatus processing DNA double-strand breaks in stationary phase. An orthologous Ligase C (LigC) complex also co-exists in many bacterial species but its function is unknown. Here we show that the LigC complex interacts with core BER enzymes in ...
