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 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.
