What will happen to a reaction that is catalyzed by a particular enzyme if the enzyme has been changed by a mutation?
Biochemistry problem: In an enzyme catalyzed reaction a Vmax of 5 nM/sec has been reported. If the amount of enzyme used in this reaction is 2 μg and the molecular weight of the enzyme is 120,000 then what will be the TON in this enzyme catalyzed reaction?
Under what circumstances does an enzyme catalyzed reaction rate resemble a non-enzyme catalyzed reaction? At very low concentrations of substrate (Km is greater than S) the Michaelis-Menton equation can be simplified to? At very high concentrations of substrate, the Michaelis-Menton equation can be simplified to? How do you determine the initial rate of reaction
Uncatalyzed Catalyzed Enzyme-substrate Complex In the above reaction, the lower curve is an enzyme-catalyzed reaction where the activation energy is notably lower than the uncatalyzed reaction. Suppose the enzyme in the diagram was mutated in such a way that its affinity for the substrate increased 100 fold, thereby affecting the enzyme-substrate complex portion of the curve. Assume that there was no other effect. Would you expect the reaction rate catalyzed by the altered enzyme to be faster, slower, or equal...
Temperature can affect enzyme-catalyzed reaction rates. What is the temperature option for trypsin? What would happen if the experiment was done at trypsin’s optimum pH but at 4 degrees celsius? 50 degrees Celsius? 100 degree Celsius?
Enzyme Kinetics Problem The initial rate for an enzyme-catalyzed reaction has been determined at a number of substrate concentrations. Data are given below: 5 27 23 65 1.

8. For the simplified representation of an enzyme-catalyzed reaction shown below, the statement "ES is in steady-state" means that: ki E+S ES – E+P kit2 a. kz is very slow. b. k1 = k. c. k1 = k-1. d. ki[E][S] = k-1[ES] + ka[ES]. e. ki[E][S] = k-1[ES]. 9. . You are examining the effects of a mutation in the proximal histidine of a heme-containing protein. This mutation has changed the histidine into an alanine. Based on your knowledge of...
