In vivo protein interaction network analysis reveals porin-localized antibiotic inactivation in Acinetobacter baumannii strain AB5075

The bacterial pathogen Acinetobacter baumannii has evolved resistance to many antibiotics, including carbapenems. Here, Wu et al. show that the carbapenemase Oxa-23 interacts with the outer membrane porin CarO in an A. baumannii isolate, indicative of porin-localised antibiotic inactivation.
