Abstract excerpt
Escherichia coli cells growing in the presence of some D-amino acids incorporate D-amino acid into the peptidoglycan layer of the cell wall by a mechanism most likely independent of the normal biosynthetic pathway. Analysis of the sensitivity of mutant strains with impaired penicillin-binding proteins (PBP) to D-amino acids indicated that ponB and DD-endopeptidase/DD-carboxypeptidase-I-defective strains are...
