La novobiocina agisce sulla subunità B della DNA-girasi, enzima che permette la replicazione del DNA, risolvendone i superavvolgimenti causati dallo srotolamento dei filamenti della doppia elica aperta per la duplicazione. L'azione è simile a quella degli antibiotici chinolonici, che però sono attivi sulla subunità A. L'uso combinato di questi due antibiotici ne potenzia l'effetto e non presenta resistenza crociata.

WebNovobiocin is an antibiotic designed to target DNA gyrase, a bacterial type IIA topoisomerase [66]. Novobiocin acts by competitive inhibition of DNA gyrase ATP hydrolysis [67]. While this compound is a catalytic inhibitor of DNA gyrase, it is also a weak catalytic inhibitor of mammalian Top2 [1]. WebNovobiocin resistance is intrinsic in S. saprophyticus. The mechanisms of novobiocin resistance include inhibition of cell wall synthesis as well as protein and nucleic acid synthesis. The Novobiocin Disk can therefore be used to differentiate S. saprophyticus from other coagulase-negative staphylococci.
