  ABSTRACT  
 
Polypeptide deformylase (PDF) catalyzes the deformylation of polypeptide chains in bacteria. It is essential for bacterial cell viability and is a potential antibacterial drug target. Here, we report the crystal structures of polypeptide deformylase from four different species of bacteria: Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, and Escherichia coli. Comparison of these four structures reveals significant overall differences between the two Gram-negative species (E. coli and H. influenzae) and the two Gram-positive species (S. pneumoniae and S. aureus). Despite these differences and low overall sequence identity, the S1' pocket of PDF is well conserved among the four enzymes studied. We also describe the binding of nonpeptidic inhibitor molecules SB-485345, SB-543668, and SB-505684 to both S. pneumoniae and E. coli PDF. Comparison of these structures shows similar binding interactions with both Gram-negative and Gram-positive species. Understanding the similarities and subtle differences in active site structure between species will help to design broad-spectrum polypeptide deformylase inhibitor molecules.

Figure 2. Crystal structures of E. coli, H. influenzae, S. aureus, and S. pneumoniae PDF. Comparison of the crystal structure of PDF from E. coli (cyan), H. influenzae (dark blue), S. pneumoniae (green), and S. aureus (yellow). (A) S. pneumoniae and S. aureus PDF. (B) E. coli and H. influenzae PDF. (C) All four species of PDF. The bound nickel is in red, and His 132, His 136, and Cys 90 are shown as a ball-and-stick representation. S. pneumoniae PDF is 13 residues longer at the N terminus than S. aureus PDF. The major difference between PDF from E. coli and from H. influenzae is the angle of the C-terminal -helix. This is mainly due to the presence of bulky Phe 96 in H. influenzae PDF (Q in E. coli PDF), which packs against the C-terminal -helix. The figure was made using RIBBONS (Carson 1991).

Figure 5. Binding of SB-543668 and SB-505684 to E. coli and S. pneumoniae PDF. SB-505684 binding to E. coli PDF (A) and S. pneumoniae PDF (B); SB-543668 binding to E. coli PDF (C) and S. pneumoniae PDF (D). Inhibitor molecules are colored in red, hydrogen bonds are marked as dashed lines, and water molecules are shown as red spheres. The figure was prepared with XTALVIEW (McRee 1993).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
