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.

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.

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

AbstractDNA ligases catalyze the formation of phosphodiester bonds between juxtaposed 5' phosphate and a 3'‐hydroxyl terminus in duplex DNA. This activity can repair single‐stranded nicks in duplex DNA and join duplex DNA restriction fragments having either blunt ends or homologous cohesive ends. Two ligases are used for nucleic acid research and their

Prokaryotic DNA Ligases Unwind Superhelical DNA
Biochemical and Biophysical Research Communications, 1996We have studied the effect on DNA topology of binding of prokaryotic DNA ligases (T4 and E. coli) to superhelical or nicked circular DNA. Performing topoisomerase I-mediated relaxation in the presence of increasing amounts of T4 ligase led to a shift in the topoisomer distribution to increasingly more negative values.
