Low-affinity penicillin-binding protein associated with beta-lactam resistance in Staphylococcus aureus.

TL;DR: A high-molecular-weight PBP (PBP-2a; approximate size, 78,000 daltons) was detected that was only present in the resistant bacteria but not in the isogenic sensitive strain, and in cultures grown at pH 5.2, the extra PBP was not detectable.
