DNA ligase (LigD) is an enzyme which repairs single-stranded breaks in a double-stranded DNA. LigD is activated , in a species-dependent manner, by hydrolysis of ATP or NAD+. Mamlian LigD I ligates the nascent DNA of the lagging strand; LigD III complexes with XRCC1 in the process of nucleotide excision repair; LigD IV complexes with XRCC4 and catalyzes the last step in the non-homologous DNA end joining.
