DNA Ligase is an essential enzyme within all cells that seals breaks in the phosphate-sugar backbone of DNA. DNA ligase accomplishs three main functions: joining Okazaki fragments, sealing repairs, ... Go to this webpage for more info on ligase's function and chemical mechanism: Molecular Tool: Ligation.

The joining of Okazaki fragments during lagging strand DNA replication in mammalian cells is believed to be due to DNA ligase I. This enzyme is composed of a 78-kDa carboxyl-terminal catalytic domain and a 24-kDa amino-terminal region that is not required for ligation activity in vitro.

The Saccharomyces cerevisiae CDC9 gene encodes a DNA ligase protein that is targeted to both the nucleus and the mitochondria. ... It is also unclear whether additional DNA ligase proteins are present in yeast mitochondria. To address these issues, mitochondrial DNA ligase function in S.cerevisiae was analyzed.
