Eukaryotic DNA ligases

Mutation Research DNA Repair, 1990
Recent studies on eukaryotic DNA ligases are briefly reviewed. The two distinguishable enzymes from mammalian cells, DNA ligase I and DNA ligase II, have been purified to homogeneity and characterized biochemically. Two distinct DNA ligases have also been identified in Drosophila melanogaster embryos.

DNA Ligases

Current Protocols in Molecular Biology, 2011
AbstractThe DNA ligase enzyme family catalyzes the formation of a phosphodiester bond between juxtaposed 5′‐phosphate and 3′‐hydroxyl termini in duplex DNA. This activity can seal nicks in duplex DNA or join double‐stranded DNA fragments having either blunt or cohesive ends.

Mammalian DNA ligases

BioEssays, 1997
AbstractDNA joining enzymes play an essential role in the maintenance of genomic integrity and stability. Three mammalian genes encoding DNA ligases, LIG1, LIG3 and LIG4, have been identified. Since DNA ligase II appears to be derived from DNA ligase III by a proteolytic mechanism, the three LIG genes can account for the four biochemically distinct DNA
