General annotation (Comments)

Function

DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. Interaction with PCNA enhances ligase activity. HAMAP MF_00407

Catalytic activity

ATP + (deoxyribonucleotide)(n) + (deoxyribonucleotide)(m) = AMP + diphosphate + (deoxyribonucleotide)(n+m). HAMAP MF_00407

Cofactor

Divalent metal cations. Ref.2

Subunit structure

Interacts with the PCNA heterotrimer. Ref.2

Sequence similarities

Belongs to the ATP-dependent DNA ligase family.
