Abstract:The resistance-nodulation-division (RND) family of efflux pumps confer clinically relevant antibiotic resistance in Gram-negative bacteria, such as Salmonella enterica. RND pumps, including AcrB, are organized as tri-partite systems, consisting of an inner membrane RND pump, a periplasmic adaptor protein (PAP) and an outer membrane channel. Previously, inactivation of the PAPs AcrA and AcrE in S. enterica has been shown to significantly increase susceptibility to antimicrobials and reduce virulence. Therefore,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
