Descripción
Methicillin-resistant Staphylococcus aureus (MRSA), an important human pathogen, has evolved an inducible mechanism for resistance to β-lactam antibiotics. We report herein that the integral membrane protein BlaR1, the β- lactam sensor/signal transducer protein, is phosphorylated on exposure to β-lactam antibiotics. This event is critical to the onset of the induction of antibiotic resistance. Furthermore, we document that BlaR1 phosphorylation and the antibioticresistance phenotype are both reversed in the presence of synthetic protein kinase inhibitors of our design, restoring susceptibility of the organism to a penicillin, resurrecting it from obsolescence in treatment of these intransigent bacteria.
