Application
Cefradin is a semi-synthetic cephalosporin antibiotic that is used to study the effect of expression, binding, and inhibition of PBP3 and other penicillin-binding proteins (PBPs) on bacterial cell wall mucopeptide synthesis.
Cefradin is used to study the effect of expression, binding, and inhibition of PBP3 and other penicillin-binding proteins (PBPs) on bacterial cell wall mucopeptide synthesis.
Biochem/physiol Actions
Cefradin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins (PBPs), such as PBP3, which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Cefradin may interfere with autolysin inhibitors.
