Comments [?]

Function DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA.
Catalytic activity Reaction=NAD(+) + (deoxyribonucleotide)(n)-3'-hydroxyl + 5'-phospho-(deoxyribonucleotide)(m) = (deoxyribonucleotide)(n+m) + AMP + beta-nicotinamide D-nucleotide.; EC=6.5.1.2;
Cofactor Mg(2+)
Mn(2+)
Similarity Belongs to the NAD-dependent DNA ligase family. LigA subfamily.
