D. Two physical
5. A protein unfolds according to the scheme N
properties (property 1 and 2) are measured at three points in the unfolding
reaction where the true values of fp are 0.2, 0.5 and 0.8. The corresponding
values of K = fx/ fp are 1.0, 0.4 and 0.125. For property 1, d₁ = 0.1; for property
2, d₁ = 0.2.
(a) Write an equation that can be used to calculate fapp.
(b) Calculate fapp using d₁ = 0.1 (property 1) and fapp using d₁ = 0.2
(property 2).
(c) The error in measurement of each physical property is 5 %. Can
you detect the presence of the intermediate by measuring the
physical properties? Explain your answer

- Need help. (a) Two ligands bind to the same site of a protein. However, when examined by ITC, for one of the ligands heat needs to be added to the system to maintain constant temperature, whereas for the other ligand, heat must be removed.

For each of the given proteins: Draw the final location of the following proteins after being translocated. • Label the organelle (as well as the organelle parts/compartments) and the cytosol (if necessary) in order to clearly depict the protein's location and orientation. • Label the amino and carboxyl ends of the protein.

- Docking and Membrane Fusion. Q-8a. Choose from the terms below to Fill-in the Blanks. [All terms are used. Some terms are used more than once] Rab, SNARE, v- SNARE, t-SNARE, Tethering a. Identification of a vesicle to be docked depends on a diverse family of monomeric GTPases called proteins. First, a filamentous protein on a target membrane binds to a protein on the surface of a vesicle. This interaction allows the vesicle to dock on its particular target membrane. A on the vesicle then binds to a complementary_ on the target membrane. Whereas and proteins provide the initial recognition between a vesicle and its target membrane, complementary appropriate target membranes. Together, the proteins ensure that transport vesicles dock at their proteins catalyze the final fusion of the two membranes by squeezing out water making fusion more energetically favorable. b. What does the acronym SNARE stand for? c. Membrane fusion the rate limiting step of vesicular transport. Why? (What makes…arrow_forwardproteins. Which of the following will tell you whether a protein would be found in the lumen of the ER? A. You run a hydropathy plot an look for hydrophobic peaks that span 20-30 amino acids B. You isolate microsomes and see whether the proteins are inserted into the membrane of the microsome C. You run a hydropathy plot an look for a lack of hydrophobic peaks that span 20-30 amino acids O D. You do in vitro translation of each protein in the presence or absence of microsomes and look to see whether there is a size change in the presence of microsomes.arrow_forwardH2. You take the PKA catalytic subunit, the regulatory subunit, and the dimerization domains and mix them in two different test tubes. One contains cAMP and one does not. You want to see if they formed a complex, so design an experiment that'd allow you if they did or did not, but you are not allowed to covalent modify any of the proteins before mixing them.arrow_forward
