Be sure tо аnswer bоth 'а' аnd 'b' and clearly identify yоur answers. You are studying a protein that normally resides in the plasma membrane. The organization of this protein is depicted below, where the gray boxes labeled A, B, and C represent transmembrane regions and the segments labeled 1, 2, 3, and 4 represent the portions of the protein between the transmembrane regions. a. If you also know that segments 2 and 4 contain N-linked oligosaccharides, You are given an image of the topographical map of this protein below. Which side of the ER membrane (A or B) would be the ER lumen, and which would be the cytosolic side? For full credit, briefly explain your answer and rationale. b. Describe the charge distribution around the first start/stop sequence that would result in the orientation shown above. Be sure to briefly describe why this is the case: (+) = area consisting of some positively charged (basic) amino acids, (-) = area consisting of some negatively charged (acidic) amino acids
(Questiоns 25 – 27) Yоu аre wоrking with some temperаture sensitive yeаst strains that you received from a professor. However, your careless professor (let’s just call him/her Dr. ‘D’) forgot to label the three strains appropriately so now he/she has left it to you to determine experimentally which strain is which. You know you have 3 strains: (A) one defective in the SAM complex (not involved in transport into the mitochondrial matrix) (B) one defective in both the TOM complex and the TIM23 complex, and (C) one defective in the signal peptidase that exists in the mitochondrial matrix. Fortunately, you have antibodies against Cox4, a subunit of cytochrome c oxidase. Cox4 normally resides in the mitochondrial matrix and is encoded by a nuclear gene. Therefore, it must be translocated into the mitochondria. You conduct some experiments in which you lyse wild-type cells and the three unknown strains in such a way that the mitochondrial proteins can be analyzed separately from the rest of the cell (cytoplasmic fraction). Then, for each strain, you separate the cytoplasmic fraction and the mitochondrial fraction by electrophoresis on an SDS gel. Your results are depicted in Figure Q12-4, in which C indicates the cytoplasmic fraction and M the mitochondrial fraction. From these results, identify which strain (Strain 1, 2, or 3 above) contains which mutation ("A" = defect in SAM complex which would not affect import to the matrix, "B" = defect in TOM and TIM, or "C" = defect in mitochondrial signal peptidase which would cleave the mitochondrial signal peptide once in the mitochondria). 25) Strain 1 (str 1) is mutation [25]; Answer "A", "B", or "C" 26) Strain 2 (str 2) is mutation [26]; Answer "A", "B", or "C" 27) Strain 3 (str 3) is mutation [27]; Answer "A", "B", or "C"
