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