| Outline of Final Research Achievements |
beta-Lactamases are the main cause of bacterial beta-lactams resistant.However, the emergence of novel beta-lactamases with direct carbapenem-hydrolyzing activity (carbapenemase) has contributed to an increased prevalence of carbapenem-resistant Enterobacteriaceae (CRE). In this study, we studied three subjects, which are concerned with beta-lactamase inhibition mechanism by carbapenems or carbapenemase inhibitor, avibactam.
(1) PenA class A carbapenemase PenA complex with avibactam. (2) Fox-4 plasmid mediated class C beta-lactamase in complex with avibactam. (3) Enterobacter cloacae P99 class C beta-lactamase in complex with biapenem.
