2 Multiple choice questions

  1. Prevents cross-linking of peptides and synthesis of peptide strnd through autolysin activators. Does not allow enzyme to cross link peptide strands.

    Methicillin, Oxacillin, Nafcillin, Cloxacillin, Dicloxacillin
  2. Come from the fungus CephalosporiumAcremonium.

    Work by the same mechanisms as penicillin's; but work on gram (+), not effective against gram (-)

    Have beta-lactam ring with dihydrothiazine ring, makes more resistant to beta-lactamases

2 True/False questions

  1. CycloserineCome from the fungus CephalosporiumAcremonium.

    Work by the same mechanisms as penicillin's; but work on gram (+), not effective against gram (-)

    Have beta-lactam ring with dihydrothiazine ring, makes more resistant to beta-lactamases

          

  2. BacitracinInhibits linkages of peptidoglycan constituents.

    Prevents incorporation of N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) peptide subunits into the peptidoglycan matrix (structural compenent of gram + cell wall)

    Large hydrophobic molecule that forms hydrogen bonds with terminal D-alanyl-D-alanine moieties of the NAM/NAG-peptides

    Binding to D-Ala-D-Ala prevents incorporation of the NAM/NAG-peptide subunits into the peptidoglycan matrix
