Pfizer Global Research and Development, Eastern Point Road, Groton, CT 06340, USA. aeruginosa PBP3 and open avenues for future design of inhibitors of this class of PBPs. Taken together, these structural, biochemical, and computational studies provide a molecular basis for recognition of P. Energetic analysis of tightly and loosely held computed hydration sites indicates protein desolvation effects contribute significantly to PBP3 binding, and analysis of hydration site energies allows rank ordering of the second-order acylation rate constants. This is also the first example of a siderophore-conjugated triazolone-linked monocarbam complexed with any PBP. Importantly, we have identified a novel conformation that is distinct to the high-molecular-weight class B PBP subfamily, which is identifiable by common features such as a hydrophobic aromatic wall formed by Tyr503, Tyr532, and Phe533 and the structural flexibility of Tyr409 flanked by two glycine residues. aeruginosa in complex with AIC499 DOI: 10.2210/pdb7onk/pdb Primary publication DOI: 10. The structure of MC-1, a new siderophore-conjugated monocarbam complexed with PBP3 provides molecular insights for lead optimization. PDB Entry - 7ONK (Status - Released) Summary information: Title: Crystal structure of PBP3 from P. aeruginosa PBP3 is due to a distinct hydrophobic aromatic wall composed of Tyr503, Tyr532, and Phe533 interacting with the gem-dimethyl group. The well-known affinity of the monobactam aztreonam for P. These structures reveal a conformational rearrangement of Tyr532 and Phe533 and a ligand-induced conformational change of Tyr409 and Arg489. aeruginosa PBP3 with both novel and marketed β-lactams.
