Question

Transcribed Image Text:You need to identify which antibiotic was used per set-up (see figure). Listed below are some
essential information.
Antibiotic A: 0.5 kDa protein, targets
peptidoglycan Antibiotic B: 20 kDa protein,
targets peptidoglycan Antibiotic C: Cationic
antimicrobial peptide Antibiotic D: Targets
lipopolysaccharide
Staphylococcus aureus: gram-positive
bacterium Vibrio cholera: gram-negative
bacterium Methanosarcina: an archaean
bacterium
Cationic antimicrobial peptides (CAMPS): these positively charged antibiotics are attracted to
the negatively charged cell wall and membrane. They are hydrophobic, and they insert into the
membranes to create pores.
