Questions 13-17 apply to the description of the organism provided below. You are studying a microorganism that was isolated near a hydrothermal vent in the ocean (temperature 82oC, pH 4).  It can produce energy from H2S using either aerobic respiration (H2S + 0.5 O2 → So + H2O) or anaerobic respiration (4H2S + NO3- + 2H+ → 4So + NH4+ + 3H2O).  In addition the organism uses CO2 as a carbon source.

After exposing multiple microorganisms to goatacillin, you find that both Gram positive and Gram negative organisms are sensitive to your antibiotic.  However, you discover that of the two strains of Escherichia coli you tested in your lab, one is sensitive and the other is resistant.  When you compare the two strains of E. coli after antibiotic exposure you see the results shown in Figure 1. Figure 1. Effects of goatacillin on a resistant strain of E. coli (A) and a sensitve strain of E. coli (B).  What protein is a likely target of goatacillin and what mechanism could provide resistance to the E. coli strain in Figure 1A?  To completely answer this question, address the following prompts. Name the protein you believe to be targetted by goatacillin. (One word maximum) Describe the function of that protein including any interactions it has with other proteins in the cell. (Five sentences maximum) Describe one mechanism that could provide the E. coli strain in Figure 1A resistance to goatacillin.  Choose a resistance mechanism that is not intrinsic to the cell envelope.  (Three sentences maximum)
