Evolved DNAzymes and Stable Activation Chemistry Enable High-Efficiency DNA Ligation. [PDF]

Chemistry
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair [PDF]

, 2018
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A.

A Mutant of Bacteriophage T7 Deficient in Polynucleotide Ligase

Journal of Biological Chemistry, 1971
Abstract An amber mutant of bacteriophage T7, obtained by mutagenesis with hydroxylamine, fails to induce the T7 polynucleotide ligase upon infection of Escherichia coli. The mutant (T7amHA13) grows normally on a suppressor-negative host; its sensitivity to ultraviolet light is the same as that of wild type T7.

Enzymes involved in DNA ligation and end-healing in the radioresistant bacterium [PDF]

, 2007
BACKGROUND: Enzymes involved in DNA metabolic events of the highly radioresistant bacterium Deinococcus radiodurans are currently examined to understand the mechanisms that protect and repair the Deinococcus radiodurans genome after extremely high doses ...

Polynucleotide Ligase Activity of Eukaryotic Topoisomerase I [PDF]

Molecular Cell, 1998
Introduction of a single ribonucleoside immediately 5' of the scissile phosphate of a duplex DNA substrate converts eukaryotic topoisomerase I into an endoribonuclease. Here, I demonstrate that the RNase reaction is reversible. Vaccinia topoisomerase can ligate 2', 3'-cyclic phosphate and 5'-hydroxyl termini annealed to a bridging template strand ...

Structure and Function of a Mycobacterial NHEJ DNA Repair Polymerase [PDF]

, 2006
Non homologous end-joining (NHEJ)-mediated repair of DNA double-strand breaks in prokaryotes requires Ku and a specific multidomain DNA ligase (LigD).

Therapeutic opportunities within the DNA damage response [PDF]

, 2015
The DNA damage response (DDR) is essential for maintaining the genomic integrity of the cell, and its disruption is one of the hallmarks of cancer.

Purification and Properties of a Polynucleotide Ligase from Human Cell Cultures [PDF]

European Journal of Biochemistry, 1971
A polynucleotide ligase has been detected and purified over 300‐fold from human cells cultured in vitro. The enzymic activity is dependent on ATP and Mg2+. The pH curve is bimodal with two optima at pH 7.5 and 8.1. The purified enzyme requires for its activity a heat‐resistant protein factor present in the crude extract.
