DNA ligases join breaks in the phosphodiester backbone of DNA molecules and are used in many essential reactions within the cell. All DNA ligases follow the same reaction mechanism, but they may use either ATP or NAD+ as a cofactor. All Bacteria (eubacteria) contain NAD+‐dependent DNA ligases, and the uniqueness of these enzymes to Bacteria makes them ...

Escherichia coli DNA ligase B may mitigate damage from oxidative stress. [PDF]
Escherichia coli encodes two DNA ligases, ligase A, which is essential under normal laboratory growth conditions, and ligase B, which is not. Here we report potential functions of ligase B.

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 ...

High-fidelity DNA ligation enforces accurate Okazaki fragment maturation during DNA replication
DNA ligase 1 (LIG1) finalizes eukaryotic nuclear DNA synthesis by sealing Okazaki fragments using DNA end-joining reactions. Here the authors, by studying an engineered low-fidelity LIG1, reveal that LIG1 is a highly accurate DNA ligase in vivo.

SUMO chain formation is required for response to replication arrest in S. pombe [PDF]
SUMO is a ubiquitin-like protein that is post-translationally attached to one or more lysine residues on target proteins. Despite having only 18% sequence identity with ubiquitin, SUMO contains the conserved betabetaalphabetabetaalphabeta fold present in
