Chains	Accession	Name	Description	Comments	Source
A	PF04675	DNA ligase N terminus (DNA_ligase_A_N)	DNA ligase N terminus	-	Family
A	PF01068	ATP dependent DNA ligase domain (DNA_ligase_A_M)	ATP dependent DNA ligase domain	This domain belongs to a more diverse superfamily, including Pfam:PF01331 and Pfam:PF01653 [3].	Domain
A	PF04679	ATP dependent DNA ligase C terminal region (DNA_ligase_A_C)	ATP dependent DNA ligase C terminal region	This region is found in many but not all ATP-dependent DNA ligase enzymes (EC:6.5.1.1). It is thought to constitute part of the catalytic core of ATP dependent DNA ligase [1].	Domain
