Kinetic mechanism and fidelity of nick sealing by Escherichia coli NAD(+)-dependent DNA ligase (LigA)
Escherichia coli DNA ligase (EcoLigA) repairs 3′-OH/5′-PO(4) nicks in duplex DNA via reaction of LigA with NAD(+) to form a covalent LigA-(lysyl-Nζ)–AMP intermediate (step 1); transfer of AMP to the nick 5′-PO(4) to form an AppDNA intermediate (step 2); and attack of the nick 3′-OH on AppDNA to form...
