Protein attributes

Sequence length	487 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	DNA ligase, which is expressed in the early stage of lytic development, has been implicated in T4 DNA synthesis and genetic recombination. It may also play a role in T4 DNA repair.
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.
