ATP-dependent cellular enzyme which catalyzes DNA replication, repair and recombination through formation of internucleotide ester bonds between phosphate and deoxyribose moieties. Vertebrate cells encode three well-characterized DNA ligases, DNA ligase I, III and IV, all of which are related in structure and sequence. DNA ligases either require ATP or NAD. However, archaebacterial, viral, and some eubacterial DNA ligases are ATP-dependent.
