NCIt definition : A broad-spectrum, semi-synthetic penicillin antibiotic with bactericidal and beta-lactamase
resistant activity. Carbenicillin acylates the penicillin-sensitive transpeptidase
C-terminal domain by opening the lactam ring. This inactivation prevents the cross-linkage
of peptidoglycan strands, thereby inhibiting the third and last stage of bacterial
cell wall synthesis. This leads to incomplete bacterial cell wall synthesis and eventually
causes cell lysis.;
