General annotation (Comments)

Function	Efficiently joins single-strand breaks in a double-stranded polydeoxynucleotide in an ATP-dependent reaction. Involved in DNA nonhomologous end joining (NHEJ) required for double-strand break repair By similarity.
Catalytic activity	ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).
Cofactor	Magnesium By similarity.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the ATP-dependent DNA ligase family. Contains 2 BRCT domains.
