CC   -!- FUNCTION: DNA ligase that seals nicks in double-stranded DNA during DNA
CC       replication, DNA recombination and DNA repair (By similarity). Has weak
CC       intrinsic nick joining activities and accumulates DNA-adenylate. Acts
CC       as a backup for LigD in the Ku-LigD-dependent NHEJ pathway.
CC       {ECO:0000250, ECO:0000269|PubMed:18281464}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + (deoxyribonucleotide)n-3'-hydroxyl + 5'-phospho-
CC         (deoxyribonucleotide)m = (deoxyribonucleotide)n+m + AMP +
CC         diphosphate.; EC=6.5.1.1;
CC   -!- DISRUPTION PHENOTYPE: Not essential; a double ligC1-ligC2 mutant grows
CC       normally, no effect on NHEJ. In a triple deletion with ligD NHEJ on
CC       blunt-ended plasmid is 90-fold impaired. In quadruple ligB-ligC1-ligC2-
CC       ligD deletions NHEJ on blunt and 5'-overhangs is 0.22 and 0.12% of
CC       wild-type respectively; only 4-fold decrease in 3'-overhang NHEJ.
CC       {ECO:0000269|PubMed:15778718, ECO:0000269|PubMed:18281464}.
CC   -!- SIMILARITY: Belongs to the ATP-dependent DNA ligase family.
CC       {ECO:0000305}.
