You have the following buffer recipe and decide to make up some concentrated solutions first so that you won't have to weigh out dry ingredients, wait for them to dissolve, and correct the pH every time you make it. How much dry ingredients do you use for each of the following 4 stock solutions? Show you work and include units in your calculations. The Buffer Recipe is: 150 mM NaCl (formula weight 58.44 g) 10 mM Tris pH 8.0 (formula weight 121 g) 2 mM EDTA (formula weight 292 g) 0.2% bovine serum albumin Stock 1 of 4: 3 M NaCl, 100 mL ________ ?

a. What are the steps/characteristics of lysosome centered protein degradation? Discuss any specificities and give an example of at least one protein which is cleared via the lysosomal degradation.

  

b. What are the steps in the proteasome centered protein degradation via ubiquitination? Include the labeling with ubiquitin and the steps in proteasome and post proteasome processing. Discuss any specificities and give an example of at least one protein which is degraded via ubiquitination and the proteasome.

  

iv) Protein degradation may also be a way of regulating enzyme activities. What is an example of regulation of a key enzyme of a pathway where a product or effector regulates enzyme activity by increasing or decreasing the rate of degradation of the enzyme protein?
