Publication Abstract from PubMed
NAD(+)-dependent DNA ligases (LigA) are ubiquitous in bacteria and essential for growth. Their distinctive substrate specificity and domain organization vis-a-vis human ATP-dependent ligases make them outstanding targets for anti-infective drug discovery. We report here the 2.3 A crystal structure of Escherichia coli LigA bound to an adenylylated nick, which captures LigA in a state poised for strand closure and reveals the basis for nick recognition. LigA envelopes the DNA within a protein clamp. Large protein domain movements and remodeling of the active site orchestrate progression through the three chemical steps of the ligation reaction. The structure inspires a strategy for inhibitor design.
