And that's enough of an explanation, most of the time, for most of us. WebPenicillinase is a bacterial enzyme produced by bacteria resistant to other β-lactam antibiotics which hydrolyses the antibiotic, rendering it non-functional. Methicillin is not bound and hydrolysed by penicillinase, meaning it can kill the bacteria, even if this enzyme is present. Medicinal chemistry [ edit] jouete アクセサリー
