Abstract: In this chapter, we describe the step-by-step identification of a putative regulator protein and demonstrate the function of this protein as a repressor of the expression of a specific efflux pump, causing resistance to quinolones in Staphylococcus aureus. We show that the knockout gene mutant has an increase in transcript levels of the target efflux pump when compared to that of the S. aureus parental strain RN6390. We provide a detailed protocol that includes the identification of the DNA-binding transcripti…
