Chapter 19.5, Problem 11QC
Summary Introduction
To review:
The role of prostacyclin in the regulation of hemostasis.
Introduction:
Hemostasis is a process in which bleeding is stopped from wounds. During the process, the wound and bleeding attracts platelets to aggregate and convert into large groups. Then the platelets move to the injured location and gather around the bleeding blood vessel. The platelets cause the blood to thicken and turn from a liquid, to a gel form, then the damaged blood vessel is repaired.

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.
