A protein was purified and then analyzed on a size exclusion column. Its MW was determined to be 50,000 Dalton. The SDS-PAGE gel shows two bands, corresponding to molecular weights of 10,000 and 15,000 Dalton. Describe the native conformation of this protein in terms of the number of subunits present and their molecular weight.

Please describe the protein purification process with the aim of purifying a protein which locates on nucleus membrane.
(c) The tube and cylinder diagram to the right illus- trates schematically the potassium channel protein from a bacterium. This channel protein consists of four identical polypeptide chains each comprised of 119 residues. The cyan ribbon illustrates only two of the polypeptide chains. The relative positions of 4 α-helices, one from each poly- peptide chain, are shown as cylinders. The red sphere in the central part of the diagram shows the position of a potas- sium ion identified by X-ray structure analysis. A cesium ion (green sphere) was also found to be stabilized in the same position when cesium chloride was introduced into the crys- tals. The cylinders each represent an α-helix running from Tyr62 to Thr74. Considering the position of the potassium ion, in- dicate on one of the cylinders at which end of the cylinder residue Tyr62 is found and at which end residue Thr74 is found. Explain the basis of your answer? Ala23 Thr119 (d) The N- and C-terminal residues of one of the…
A number of techniques can separate proteins on the basis of their differences in mass. Describe the use of two of these techniques, centrifugation and gel electrophoresis. The blood proteins transferrin (MW 76 kDa) and lysozyme (MW 15 kDa) can be separated by rate zonal centrifugation or SDS-polyacrylamide gel electrophoresis. Which of the two proteins will sediment faster during centrifugation? Which will migrate faster during electrophoresis?
Protein a will fold into its native state only when protein b is also present in the solution however protein b can fold itself into native confirmation without the presence of protein a which of the following is true
A 20µL unknown protein was mixed with 80µL of water. Then, 10µL of this mixture was added with 10µL Bradford reagent and diluted with water to a total volume of 100µL. The absorbance at 595 nm shows 0.08 units. Solve for the protein concentration (in mg/mL) of the original unknown protein. How much protein (in mg) is in the 20uL sample? Express your answer in 3 significant figures.
Let’s suppose we have downloaded the structure of Hemoglobin from PDB. Now we want to retrieve the location of helices and loops in it. How can we do it? How can we depict a protein’s coordinate info in a modeling program? (Subject: Bioinformatics)
Describe how you might extract membrane proteins from a mouse cell culture without using a commercial kit. Your proposal should take into account that the membrane protein sample extracted should be compatible with a subsequent purification step involving ion exchange chromatography. Justify your choices of extraction steps and reagents that you might use.
