Abstract:
The N-terminal ATP binding domain of the DNA gyrase B subunit is a validated drug target for antibacterial drug discovery. Structural information for this domain (pGyrB) from Pseudomonas aeruginosa (P. ae) is still missing. In this study, the interaction between pGyrB and a bis-pyridylurea inhibitor was characterized using several biophysical methods. We further carried out structural analysis of pGyrB using NMR spectroscopy. The secondary structures of free and inhibitor bound pGyrB were obtained based on backbone chemical shift assignment. Chemical shift perturbation and NOE experiments demonstrated that the inhibitor binds to the ATP binding pocket. The results of this study will be helpful for drug development targeting P. ae.
