Function

DNLJ_ENTFA DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA (By similarity).

Publication Abstract from PubMed

In an attempt to identify novel inhibitors of NAD+-dependent DNA ligase (LigA) that are not affected by a known resistance mutation in the adenosine binding pocket, a detailed analysis of the binding sites of a variety of bacterial ligases was performed. This analysis revealed several similarities to the adenine binding region of kinases, which enabled a virtual screen of known kinase inhibitors. From this screen, a thienopyridine scaffold was identified that was shown to inhibit bacterial ligase. Further characterization through structure and enzymology revealed the compound was not affected by a previously disclosed resistance mutation in Streptococcus pneumoniae LigA, Leu75Phe. A subsequent medicinal chemistry program identified substitutions that resulted in an inhibitor with moderate activity across various Gram-positive bacterial LigA enzymes.
