CC -!- FUNCTION: DNA ligase that seals nicks in double-stranded DNA during DNA
CC replication, DNA recombination and DNA repair. {ECO:0000255|HAMAP-
CC Rule:MF_00407, 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; Evidence={ECO:0000255|HAMAP-Rule:MF_00407};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00407};
CC -!- DISRUPTION PHENOTYPE: Not essential for growth, no effect on NHEJ. In
CC quadruple ligB-ligC1-ligC2-ligD deletions NHEJ on blunt and 5'-
CC overhangs is 0.22 and 0.12% of wild-type respectively; only 4-fold
CC decrease in 3'-overhang NHEJ. {ECO:0000269|PubMed:15778718,
CC ECO:0000269|PubMed:18281464}.
CC -!- SIMILARITY: Belongs to the ATP-dependent DNA ligase family.
CC {ECO:0000255|HAMAP-Rule:MF_00407}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AFP38690.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
