Structures of LIG1 that engage with mutagenic mismatches inserted by polβ in base excision repair
Ligase I seals two ends of DNA during DNA repair and replication. Here — solving structures of Ligase I with imperfect DNA harboring mismatches incorporated by DNA polymerase — the authors reveal how the repair proteins maintain fidelity at final ligation step.
