CC   -!- FUNCTION: Catalyzes the formation of phosphodiester linkages between
CC       5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD
CC       as a coenzyme and as the energy source for the reaction.
CC       {ECO:0000255|HAMAP-Rule:MF_01587}.
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_01587};
CC   -!- SIMILARITY: Belongs to the NAD-dependent DNA ligase family. LigB
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01587}.
