A16 Compound A is the substrate for two enzymes, E, and E2, involved in the synthe- sis of an amino acid and an antibiotic, respectively. Their reaction rates, r, and r2, at an arbitrary concentration of E, and E, were measured at different concen- trations of A. However, the data were not labeled properly (shown in Table P.4.1), and the student who did the measurement needs help to sort out which dataset is for E,. Determine the K and rmax for both enzymes, with respect to the concen- tration of A. Which set of data is more likely to be for E, and which for E,, and why?

Using the appropriate graph and table above, explain what the N426S mutation appears to be doing to the enzyme’s function. Discuss the kinetic parameter changes and their meaning in this context, not the structure of the enzyme, which was not given to you.
Assume that the experiments performed in the absence of inhibitors were conducted by adding 5 μL of a 2 mg/mL enzyme stock solution to an assay mixture with a total volume of 1 mL. Take into account that XYZase is a monomeric enzyme with a molecular mass of 45,000 Daltons. Hint: To calculate the ???? in units of per second (s−1), you must first determine the ???? in micromoles per second (μmol/sec). Please explain step by step
Why do structural analogs of the transition-state intermediate of an enzyme inhibit the enzyme competitively and with low Ki values (binds tightly)?
b. Compounds A, B, C, and D are known to be intermediates in the pathway for production of protein E. To determine where the block in protein-E production occurred in each individual, the various intermediates were given to each individuals cel Is in culture. After a few weeks of growth with the intermediate, the cells were assayed for the production of protein E. The results for each individuals cells are given in the following table. A plus sign means that protein E was produced after the cells were given the intermediate listed at the top of the column. A minus sign means that the cells still could not produce protein E even after being exposed to the intermediate at the top of the column. Denote the point in the pathway in which each individual is blocked.

What features distinguish enzymes that undergo allosteric control from those that obey Michaelis-Menten equations? Give 2 differences
Pyridoxal phosphate (PLP) is a coenzyme for the enzyme ornithine aminotransferase. The enzyme was purified from cells grow in PLP = deficient media as well as from cells grown in media that contained pyridoxal phosphate. The stability of the two different enzyme preparations was then measured by incubating the enzyme at 37°C for different lengths of time and then assaying for the amount of enzyme activity remaining. The following results were obtained. (a) Why does the amount of active enzyme decrease with the time of incubation? (b) Why does the amount of enzyme from the PLP deficient cells decline more rapidly?
