6. Consider the following proteins to answer the questions below: Protein Size (kDa) pl ε at 280 nm 10 4 7000 50 4 14000 10 8 3000 50 8 50000 A B C C Red Colored? Yes No No No b. Describe a two-step purification procedure that could be used to purify/isolate protein A from the other proteins. In your response, describe the type of chromatography used, the pH of buffer needed, and a labeled chromatogram (include absorbances at both 280 and 400 nm). Make sure you note which "fraction/sample" is needed from the first step to proceed/use for the second step. Use another page if necessary.
Your research advisor would like you to measure the movement of a protein X using FRAP. The results of your FRAP experiment are shown below. What can you conclude? Fluorescence Intensity (Arbitrary Units) Time (Seconds) Time point of exposure to an intense laser Protein X appears to be completely immobilized in the membrane Protein X appears to be partially immobilized in the membrane You cannot make predictions about the mobility of Protein X with these data Protein X appears to be completely mobile in the membrane

hydrophilie hydrophobic hydrophilic 7. Glycop Short Answer Questions: 8. Explain the differences between integral, peripheral, and surface proteins. The difference is that integral proteins have part of the protein on the cutaide and the other on the hoide and span through through the membroue. Paipheral proteins pass through hydrophilic head layer and part of the hydsophabic hail laver an either side of the membrane Surface proteins sit on the surface of the membrane either inside or cutside of the cell.

Which of these compounds will cross the cell membrane without the aid of a membrane transport protein, and why? H3 NH NH 2. By what transport process will the above compound be transported? What are the factors which drive movement across the membrane in this process? Does this process require input of energy?
Please explain the correct answer
7. Specificity of membrane transporters. A protein that transports amino acids across the cell membrane was found to bind only a few amino acids efficiently. To find the specificity, many different amino acids and substrate analogs were used as competitive inhibitors in transport studies at pH 5.9 with L-histidine (Km = 10 μM). The Ki values calculated from Lineweaver-Burk plots are shown in the table below. Comparing the structures of L-histidine and the competitive inhibitors (for which most of them, you should know their structures!), what can you conclude about the characteristics of molecules that this transport protein binds at its active site?
