cell wall synthesis inhibs |
|
Definition
b lactams e.g. penicilin/cephalosporin
glycopeptides e.g. vancomycin |
|
|
Term
|
Definition
bind to PBPs = inhibit cross linking of peptidoglycans |
|
|
Term
|
Definition
bind to d-alanyl-d-alanine portion of pentapeptide required for peptidoglycan formation = no cross linking |
|

Definition
bind to 30s on ribo = non functioning initiation complexes |
|
|
Term
|
Definition
binds to 30s ribo = prevent elongation of peptide |

Definition
binds to 50s ribo =inhibits peptidyl transferase |
|
|
Term
|
Definition
inhibits formation of 50s ribo unit.
interacts with peptidyl transferase = blocks polypeptide exit tunnel = peptide dissociates from ribo during translocation
(ALSO ACTS ON HUMAN 50S RIBO UNIT = TOXICITY) |

Definition
binds to 23s ribosomal rna of 50s unit = prevents formation of initiation complex |
