General annotation (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 By similarity. HAMAP-Rule MF_01588

Catalytic activity

NAD+ + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + beta-nicotinamide D-ribonucleotide + (deoxyribonucleotide)(n+m). HAMAP-Rule MF_01588

Cofactor

Magnesium or manganese By similarity.

Sequence similarities

Belongs to the NAD-dependent DNA ligase family. LigA subfamily.

Contains 1 BRCT domain.
