KPC Beta-Lactamases Are Permissive to Insertions and Deletions Conferring Substrate Spectrum Modifications and Resistance to Ceftazidime-Avibactam

To explore the mutational possibilities of insertions and deletions (indels) in the Klebsiella pneumoniae carbapenemase (KPC) beta-lactamase, we selected for ceftazidime-avibactam-resistant mutants. Of 96 screened mutants, we obtained 19 indels (2 to 15 amino acids), all located in the loops surroun...
