CRYSTAL STRUCTURE OF THE BACILLUS SUBTILIS PBP4A, AND ITS COMPLEX WITH A PEPTIDOGLYCAN MIMETIC PEPTIDE.
OverviewOverview
The genome of Bacillus subtilis encodes 16 penicillin-binding proteins, (PBPs) involved in the synthesis and/or remodelling of the peptidoglycan, during the complex life cycle of this sporulating Gram-positive rod-shaped, bacterium. PBP4a (encoded by the dacC gene) is a low-molecular mass PBP, clearly exhibiting in vitrodd-carboxypeptidase activity. We have solved, the crystal structure of this protein alone and in complex with a peptide, (d-alpha-aminopymelyl-epsilon-d-alanyl-d-alanine) that mimics the, C-terminal end of the Bacillus peptidoglycan stem peptide. PBP4a is, composed of three domains: the penicillin-binding domain with a fold, similar to the class A beta-lactamase structure and two domains inserted, between the conserved motifs 1 and 2 characteristic of the, ...
