Abstract
DNA ligase D (LigD), consisting of polymerase, ligase and phosphoesterase domains, is the essential catalyst of the bacterial non-homologous end-joining pathway of DNA double-strand break repair. The phosphoesterase (PE) module performs manganese-dependent 3′-phosphomonoesterase and 3′-ribonucleoside resection reactions that heal broken ends in preparation for sealing. LigD PE exemplifies a structurally and mechanistically unique class of DNA end-processing enzymes. Here, we present the resonance assignments of the PE domain of Pseudomonas aeruginosa LigD comprising the N-terminal 177 residues.
