Action
Resistance Mechanism
Ampicillin
50
Inhibits cell wall synthesis by inhibiting formation of the peptidoglycan crosslink b-lactamase (286 aa) is secreted into the periplasm and cleaves lactam antibiotic
Chloramphenicol
20
Inhibits protein synthesis by interacting with the 50S ribosomal subunit and inhibiting the peptidyltransferase reaction. 216 aa protein cytoplasmic protein which acetylates chloramphenicol
Kanamycin 
Neomycin
30
Inhibits translocation and elicits miscoding by binding to the 30S ribosomal subunit. 256 aa aminoglycoside phosphotransferase phosphorylates kanamycin, neomycin, etc.
Tetracycline
12
Inhibits protein synthesis by preventing binding of aminoacyl tRNA to the ribosome A site. 428 aa membrane protein catalyzing efflux of tetracyclin, probably by a cation symport mechanism.
