DNA ligases catalyse the crucial step of joining the breaks in duplex DNA during DNA replication, repair and recombination, utilising either ATP or NAD(+) as a cofactor [1]. This family is a small zinc binding motif that is presumably DNA binding [1]. IT is found only in NAD dependent DNA ligases [1].	Domain

This family is a small domain found after the adenylation domain Pfam:PF0165 ...	DNA ligases catalyse the crucial step of joining the breaks in duplex DNA during DNA replication, repair and recombination, utilising either ATP or NAD(+) as a cofactor [1]. This family is a small domain found after the adenylation domain Pfam:PF01653 in NAD dependent ligases [1]. OB-fold domains generally are involved in nucleic acid binding.	Domain

This entry represents a SAM-like helix-hairpin-helix domain found in functionally diverse proteins involved in DNA repair, recombination, transcription termination etc. This domain has a fold that is structurally similar to SAM domains. It is composed of two helix-hairpin-helix motifs which are known DNA interaction motifs.	Domain
