CC   -!- FUNCTION: DNA ligase that seals nicks in double-stranded DNA
CC       during DNA replication, DNA recombination and DNA repair (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: ATP + (deoxyribonucleotide)(n) +
CC       (deoxyribonucleotide)(m) = AMP + diphosphate +
CC       (deoxyribonucleotide)(n+m).
CC   -!- COFACTOR: Divalent metal cations (By similarity).
CC   -!- SIMILARITY: Belongs to the ATP-dependent DNA ligase family.
