Summary Introduction

To review:

The property of an enzyme in general, which enables luciferase to attach only to luciferin molecule. Also, explain catalysis by luciferase taking this enzymatic property into consideration.

Introduction:

The fireflies show the phenomenon of bioluminescence with the help of luciferin, which is present in their abdomen in an organ known as a lantern. This reaction takes place in the presence of an enzyme luciferase, which behaves as a catalyst.

The enzyme luciferase undergoes a change in the shape when it binds to luciferin and adenosine triphosphate (ATP). This prevents the attachment of the water molecule at the active site of the enzyme.

When enzyme solutions are heated, there is a progessive loss of catalytic activty over time due to denaturation of the enzyme. A solution of the enzyme hexokinase incubated at 45 degrees Celsius lost 50% of its activity in 12 minutes, but when incubated at 45 degrees Celsius in the presence of a very large concentration of one of its substrates, it lost only 3% of its activity in 12 minutes. Suggest why thermal denaturation of hexokinase was retarded in the presence of one substrates.
For a lot of enzymes that work on fatty acids, the rate determining step is the release of the product from the active site. This means that the activation energy for product release is much higher than the free energy of catalysis. What enthalpic or entropic contributions would make the activation energy for product release so high and explain?
During chymotrypsin-mediated catalysis, which of the following statements is true? Select any/all answers that apply. O A. A basic (positively-charged) side chain of the substrate polypeptide sits within the oxyanion hole of the enzyme. O B. A basic (positively-charged) side chain of the substrate polypeptide sits within the specificity pocket of the enzyme. O C. Ser195 hydrogen-bonds with the backbone carbonyl group of the substrate polypeptide within the oxyanion hole of the enzyme. O D. All three residues that comprise the catalytic triad of the enzyme interact directly with the substrate polypeptide chain. O E. Both covalent catalysis and acid-base catalysis occur.
