Summary Introduction

To review:

The process of cell fractionation that permits the separation of proteins present in the cytoplasm, periplasm, inner and outer membrane of a cell.

Introduction:

Gram-negative is one of the types of bacteria that are not able to retain crystal violet stain from the Gram stain. The characteristic feature of Gram-negative bacteria is that the cell wall is composed of five layers of peptidoglycan. The outer membrane of such bacteria helps in protection from antibiotics.

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
