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}.
