This paper characterizes OXA-57, a class D β-lactamase from Burkholderia pseudomallei, showing its activity against penicillins and cephalosporins, limited carbapenem hydrolysis, and structural insights into its mechanism.

This study shows 3-BP covalently inhibits NDM-1 and NDM-5 MBLs, restoring carbapenem activity against resistant bacterial strains.

This study evaluates the roles of Ldt and PBP inhibition in suppressing Mycobacterium smegmatis using beta-lactams and LdtMt2 inhibitors, finding stronger growth suppression with Ldt inhibition.

This paper compares the potency of nacubactam and avibactam against OXA-48-like β-lactamases, finding that nacubactam is less potent due to electrostatic repulsion with Arg214.
