Chapter 11: Q16 P (page 359)

Would you expect lysozyme to hydrolyze cellulose? Why or why not?

Short Answer

Expert verified

Lysozyme is not anticipated to break down cellulose. Lysozyme is unable to hydrolyze the glycosidic bond in cellulose.

Step by step solution

01

Definition of "Lysozyme"

An enzyme called lysozyme is present in body fluids including saliva, milk, and tears.

02

Step 2: Expectation of lysozyme to hydrolyze cellulose

An enzyme called lysozyme breaks the glycosidic C-O link between N-acetylglucosamine and N-acetylmuramic acid. A polysaccharide called cellulose is made up of glucose residues joined together by 尾1鈫�4glycosidic linkages.

The lysozyme, as can be seen, hydrolyzes the links, but it only binds to substrates that include N-acetylglucosamine and N-acetylmuramic acid. This leads us to the conclusion that cellulose's glycosidic bond cannot be hydrolyzed by lysozyme.

Hence, lysozyme is not expected to hydrolyze cellulose.

The comparison of the active site geometries of chymotrypsin and subtilisin under the assumption that their similarities have catalytic significance has led to greater mechanistic understanding of both these enzymes. Discuss the validity of this strategy.

Hemophiliacs who lack factor IX are sometimes given infusions of factor VII to restore normal blood clotting activity. Explain.

A genetic defect in coagulation factor IX causes hemophilia b, a disease characterized by a tendency to bleed profusely after very minor trauma. However, a genetic defect in coagulation factor XI has only mild clinical symptoms. Explain this discrepancy in terms of the mechanism for activation of coagulation proteases shown in Box 11-4.
