Protein attributes

Sequence length	548 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Able to ligate a double-stranded synthetic DNA substrate containing a single nick and inefficiently ligated a 1 nucleotide gap but did not ligate a 2 nucleotide gap. It is able to ligate short, complementary overhangs but not blunt-ended double-stranded DNA. May be implicated in DNA repair and recombination.
Catalytic activity	ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m).
Cofactor	Divalent metal cations By similarity.
Sequence similarities	Belongs to the ATP-dependent DNA ligase family.
