Protein attributes

Sequence length	552 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. It is not essential for viral replication 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.
