Structures of LIG1 active site mutants reveal the importance of DNA end rigidity for mismatch discrimination

ATP-dependent DNA ligases catalyze phosphodiester bond formation in the conserved three-step chemical reaction of nick sealing. Human DNA ligase I (LIG1) finalizes almost all DNA repair pathways following DNA polymerase-mediated nucleotide insertion. We previously reported that LIG1 discriminates mi...
