Abstract

Background: Pathogenic Pseudomonas aeruginosa strains produce a colicin M-like bacteriocin exhibiting peptidoglycan lipid II-degrading activity. Results: We have determined the crystal structure of the Pseudomonas aeruginosa PaeM bacteriocin and functionally characterized its C-terminal activity domain. Conclusion: This study highlights structural plasticity of the active site of this enzyme family. Significance: The PaeM pyocin could potentially be exploited as antibacterial agent. © 2012 by The American Society for Biochemistry and Molecular Biology, Inc.
