Studies (kinetic, stereochemical, chemical modification, and site-specific mutagenesis experiments) on the enzyme triosephosphate isomerase have identified the B as Glu165 and HA as His95 (J. R. Knowles, Nature 350, 121 (1991). To aid your understanding, draw the active site as a pocket that extends into the enzyme and place the Flu and His on opposite sides of the pocket. Answer the following questions: a. Drawing of the pocket: b. How might the replacement of Glu with Asp affect the catalytic...

An experimenter performs two sets of enzyme kinetics experiments. One set of experiments, when plotted as a double-reciprocal plot, yielded a y-intercept of 0.043 μM-1·min and an x-intercept of -20.0 mM-1. A second set of experiments, when similarly plotted, yielded a y-intercept of 0.129 μM-1·min and an x-intercept of -60.0 mM-1. The second set of experiments contained 92 nM of an uncompetitive inhibitor. Given these data, what is the Ki' (in nM to the nearest tenths) for this inhibitor? Hint:...

1. When an enzyme runs a chemical reaction, what happens to the enzyme at the end of the reaction? a) it is unchanged, and can run another reaction b) it is weakened, and is slower the next time c) it becomes part of the product, and is used up d) it is permanently damaged, or destroyed 2. When an enzyme accelerates a reaction rate, what does the enzyme do, thermodynamically (energy-wise)? a)lowers the activation energy for the reaction b) allows...

Comment on the results of each of these recent experiments in light of the Old Friends hypothesis: a) A small group of Finnish children were matched at birth by age and relevant genotype, then followed to see if any developed autoantibodies typical of type I diabetes. Compared to matched healthy controls, the children who would develop T1D had markedly different gut microbiomes. Relative to those of matched healthy controls, rheir microbiomes were less diverse, more unstable, and became increasingly dominated...
