Question
Chapter 26, Problem 16DYB
Summary Introduction
To determine:
The reason that why it is important for protein-digesting enzymes to be released in an inactive form.
Concept introduction:
The complex proteins present in the diet are broken down into simpler molecules by the action of enzymes called proteases. Pepsinogen, chymotrypsinogen, trypsinogen, and procarboxypeptidase are some of the inactive proteases released in the body.

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.
