Chapter 3, Problem 13PIAT
Summary Introduction

To determine:

The frequency of proline to appear in peptide, if it were made up of a completely random assortment of the 20 most common amino acids

Given:

One of the peptides that can be recovered after gluten digestion is 33 residues long; 13 of the 33 residues are proline.

Introduction:

Gluten proteins are rich in amino acid proline, so they do not break down easily during digestion in small intestine, resulting in short and long peptides. These peptides can be broken down further and absorbed through the intestine and further can be utilized by 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. Mutation 1 Mutation 2
