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; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01588};
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01588};
CC   -!- SIMILARITY: Belongs to the NAD-dependent DNA ligase family. LigA
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01588}.
