Protein Structure

Proteases catalyze the hydrolysis of which of the following types of bonds?

Protein denaturation DOESN’T impact which of the following bonds found within a protein’s structure?

The tertiary structure of a globular protein is predominately stabilized by:

An alpha helix is primarily held together by:

Which of the following characteristics of a protein could be studied by running the protein on a denaturing gel alone?

Supramolecular structures comprised of salt-bridged calix[5]arene capsules can surround and thereby carry a wide range of hydrophobic drugs. Release of the drug can then be triggered by an external stimulus and allow for site specific drug delivery. Based on this information the interaction between which of the following amino acid residues most likely holds two parts of a calix[5]arene capsule together?

The term homodimer refers to:

Fibritin is a heterotrimeric protein whose subunits are held together by disulfide linkages. Addition of the reducing agent mercaptoethanol would result in?

Hydrogen bonds are extremely pH dependent and are disrupted at extremes of pH. If a protein was placed in a highly acidic solution which element of its structure would be most affected by the solution’s pH?

Hydrolysis by a protease directly disrupts which of the following elements of a protein’s structure?

If a monomeric protein was transferred from an aqueous solvent into an organic solvent which level of protein structure would be most significantly altered?

Which of the following mutations within a protein would increase the entropic penalty of folding significantly?
