The genetic connections between DNA repair pathways and human cancer predisposition have fueled interest in the proteins that recognize and repair specific sites of DNA damage. The repair enzymes are ...

After two fragments with complementary sticky ends are joined, the DNA backbone may be covalently sealed using another enzyme called DNA ligase.

Causes: LIG4 syndrome is caused by a mutation in the LIG4 gene, which carries the instructions needed to make a protein known as DNA ligase 4. This protein is an enzyme that helps repair a ...

The N-terminal ATP-dependent ligase domain belongs to the covalent nucleotidyltransferase enzyme superfamily that includes classic RNA/DNA ligases and mRNA capping enzymes. We’ve shown that: (i) each ...

In the early 1950s, experiments by two teams of researchers, Salvador Luria working with Mary Human and Joe Bertani working with Jean Weigle, showed that some strains of bacteria were more ...
