General annotation (Comments)

Function

DNA ligase, which is expressed in the early stage of lytic development, has been implicated in T7 DNA synthesis and genetic recombination. It may also play a role in T7 DNA repair.

Catalytic activity

ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m). Ref.5

Cofactor

Divalent metal cations By similarity.

Sequence similarities

Belongs to the ATP-dependent DNA ligase family.
