Bacterial peptide deformylase (PDF) belongs to a sub-family of, metalloproteases that catalyse the removal of the N-terminal formyl group, from newly synthesised proteins. PDF is essential in prokaryotes and, conserved throughout the eubacteria. It is therefore considered an, attractive target for developing new antibacterial agents. Here, we report, the crystal structures of four bacterial deformylases, free or bound to, the naturally occurring antibiotic actinonin, including two from the major, bacterial pathogens Pseudomonas aeruginosa and Staphylococcus aureus. The, overall tertiary structure is essentially conserved but shows significant, differences, namely at the C terminus, which are directly related to the, deformylase type (i.e. I or II) they belong to. The geometry around the, catalytic metal ion exhibits a high level of similarity within the, different enzymes, as does the binding mode of actinonin to the various, deformylases. However, some significant structural differences are found, in the vicinity of the active site, highlighting the structural and, molecular requirements for the design of a deformylase inhibitor active, against a broad spectrum of bacterial strains.
