DNA ligase
DNA ligase (NAD+) (, "polydeoxyribonucleotide synthase (NAD+)", "polynucleotide ligase (NAD+)", "DNA repair enzyme", "DNA joinase", "polynucleotide synthetase (nicotinamide adenine dinucleotide)", "deoxyribonucleic-joining enzyme", "deoxyribonucleic ligase", "deoxyribonucleic repair enzyme", "deoxyribonucleic joinase", "DNA ligase", "deoxyribonucleate ligase", "polynucleotide ligase", "deoxyribonucleic acid ligase", "polynucleotide synthetase", "deoxyribonucleic acid joinase", "DNA-joining enzyme", "polynucleotide ligase (nicotinamide adenine dinucleotide)") is an enzyme with systematic name "poly(deoxyribonucleotide):poly(deoxyribonucleotide) ligase (AMP-forming, NMN-forming)". This enzyme catalyses the following chemical reaction
