The discovery of the mechanisms of biological synthesis of nucleic acids: 1959 Nobel laureates S. Ochoa and A. Kornberg [PDF]
Alongside the chemical and physical research of nucleic acids in the 1940s-50s, the mechanisms of their biosynthesis were investigated. Thus, in 1959, Severo Ochoa and Arthur Kornberg were awarded the Nobel Prize in Physiology or Medicine for the ...

DNA Ligase IV is responsible for the repair of DNA double-strand breaks (DSB), including DSBs that are generated during V(D)J recombination. Like other DNA ligases, Ligase IV contains a catalytic core with three subdomains-the DNA binding (DBD), the ...

Comparative analysis of the end-joining activity of several DNA ligases. [PDF]
DNA ligases catalyze the repair of phosphate backbone breaks in DNA, acting with highest activity on breaks in one strand of duplex DNA. Some DNA ligases have also been observed to ligate two DNA fragments with short complementary overhangs or blunt ...

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 ...

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 ...

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.

Horizontal acquisition of a DNA ligase improves DNA damage tolerance in eukaryotes
Bdelloid rotifers are part of the restricted circle of multicellular animals that can withstand a wide range of genotoxic stresses at any stage of their life cycle. In this study, bdelloid rotifer Adineta vaga is used as a model to decipher the molecular
