Abnormal peptidoglycan produced in a methicillin-resistant strain of Staphylococcus aureus grown in the presence of methicillin: functional role for penicillin-binding protein 2A in cell wall synthesis
Abstract
Upon the addition of methicillin even at relatively low concentrations (5 mug/ml or 0.3% of the MIC) to the medium, methicillin-resistant staphylococci shift to the production of a new peptidoglycan with an abnormal muropeptide composition which may be the synthetic product of penicillin-binding protein 2A.
