Functioni

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 activityi

NAD+ + (deoxyribonucleotide)(n)-3'-hydroxyl + 5'-phospho-(deoxyribonucleotide)(m) = (deoxyribonucleotide)(n+m) + AMP + beta-nicotinamide D-nucleotide.UniRule annotation
