The signaling mechanisms used by steroid hormone type nuclear receptor and ion channel coupled receptor are relatively simple have few components and possibility and mechanism of the amplification of their initial signal. Concept introduction: Hormones are of two types, protein hormone and steroid hormones. Steroid hormones can actively diffuse across the plasma membrane as they possess hydrophobic property as well. The steroid hormones enter the nucleus with their receptor where they activate an activator and remove the repressor. The ion channel coupled receptor is present on both the plasma membrane and most of the membrane bound organelles.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
