Comparative analysis of the end-joining activity of several DNA ligases. [PDF]
PLoS ONE, 2017 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 ...
