- 286. Miraculin is a protein isolated from what is known as the "miracle berry," the fruit of a plant native to West Africa. It is described as 'miraculous' because the protein is able to alter our sense of taste. When introduced into the mouth, this protein interacts with the taste buds and makes normally sour foods taste extremely sweet-imagine biting into a lemon and tasting lemonade instead of burning acid. Researchers have created an in vitro system to test the function of this protein. Cultured cells expressing TIR2/T1R3 receptors (those that normally detect sweet taste) were tested with or without miraculin and at neutral and low pHs. Results from this experiment showing the level of sweet detection in these different treatments appear below. From these data, make conclusions about how miraculin works to affect taste. Be sure to explain your answer mechanistically. Treatment Neutral pH Low pH Sugar alone Miraculin + Sugar Miraculin alone normal detection normal detection low…7.

- 1. You are interested in the eukaryotic protein/enzyme Thiolase, which is 200 amino acids in length. Because Thiolase is only active in the peroxisome (an organelle) you know there must be a peroxisomal localization signal sequence in the protein. Sub-cellular Location Construct of GFP protein In order to be able to visualize the Thiolase protein in a cell, you create a fusion Cytosol construct with the gene for Thiolase and the GFP gene for Green Fluorescent Protein (GFP). 200 Thiolase Peroxisome GFP You also make a series of deletions in the 50 200 Peroxisome gene for Thiolase, all fused with the GFP GFP 100 200 gene. Numbers on top of the constructs GFP Peroxisome represent amino acid positions. 125 200 Cytosol GFP You express each construct in a mammalian 150 200 cell and use a microscope to visualize where the Thiolase-GFP protein gets trafficked. cytosol GEP 150 Peroxisome GFP Using the data provided, where must the peroxisomal localization signal sequence be in the Thiolase…Explain fully the ubiquitin proteosome system1.
