Direct 3:26-26(2008). CC -!- FUNCTION: DNA ligase that catalyzes the formation of phosphodiester CC linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- CC stranded DNA using NAD as a coenzyme and as the energy source for the CC reaction. It is essential for DNA replication and repair of damaged CC DNA. {ECO:0000255|HAMAP-Rule:MF_01588}. CC -!- CATALYTIC ACTIVITY: CC Reaction=NAD(+) + (deoxyribonucleotide)n-3'-hydroxyl + 5'-phospho- CC (deoxyribonucleotide)m = (deoxyribonucleotide)n+m + AMP + beta- CC nicotinamide D-nucleotide.; EC=6.5.1.2; Evidence={ECO:0000255|HAMAP- CC Rule:MF_01588}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01588}; CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01588}; CC -!- SIMILARITY: Belongs to the NAD-dependent DNA ligase family. LigA CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01588}.
