D-Amino Acid Probes for Penicillin Binding Protein-based Bacterial Surface Labeling.

Abstract excerpt

Peptidoglycan is an essential and highly conserved mesh structure that surrounds bacterial cells. It plays a critical role in retaining a defined cell shape, and, in the case of pathogenic Gram-positive bacteria, it lies at the interface between bacterial cells and the host organism. Intriguingly, bacteria can metabolically incorporate unnatural D-amino acids into the peptidoglycan stem peptide directly from the...
