Document Summary
Please provide all answers in the space provided. You may not use calculators for this exam, but you are free to use (previously unassembled!) molecular model kits. Including the title page, there should be 6 pages in this exam booklet. Name: ____________________________________________ (1) _____________ (16 points) (2) _____________ (12 points) (3) _____________ (40 points) (4) _____________ (32 points) In the space below, draw a newman projection indicating the most stable conformation along this bond. Do not abbreviate the side chain groups in your structure (i. e. don"t use r" groups) (8 points): many types of bacteria, such as staphylococcus aureus, directly attach proteins to their surfaces in order to adhere to host tissues. This process is catalyzed by an enzyme called. Sortase , which sorts through the proteins of the bacterial cell, chooses the ones that have a specific sequence at the c-terminus, and attaches them to the peptidoglycan cell wall directly (this reaction sequence is summarized in question 3b).
