Molecule diagrams generated from .mol files obtained from the KEGG ftp site.

Other name(s): Dna joinase. Dna repair enzyme. polydeoxyribonucleotide synthase (NAD(+)). polydeoxyribonucleotide synthase (NAD+). polynucleotide ligase (NAD(+)). polynucleotide ligase (NAD+).
Comments: The enzyme, typically found in bacteria, catalyzes the ligation of Dna strands with 3'-hydroxyl and 5'-phosphate termini, forming a phosphodiester and sealing certain types of single-strand breaks in duplex Dna. Catalysis occurs by a three-step mechanism, starting with the activation of the enzyme by NAD(+), forming a phosphoramide bond between adenylate and a lysine residue. The adenylate group is then transferred to the 5'-phosphate terminus of the substrate, forming the capped structure 5'-(5'-diphosphoadenosine)-[DNA].
