Protein Folding- The Basics

1

Define Protein Folding

1

Which structure of a protein shows biological activity?

1

Which of the following occurs to ALL proteins?

1

Which of the following are covalent modifications of the polypeptide chain?

1

Folding corresponds to a hierarchy of protein structure

1

Put the following in Order
A -Unfolded
B - Nucleation
C - Secondary Structure
D - Domain
E - Active Oligomer
F - Inactive Oligomer
G - Supersecondary Structure
H - Folded Monomer

1

What is meant by the 'Thermodynamic Hypothesis of Protein Folding'

1

The Kinetic Hypothysis suggests that there is a specific folding pathway for each protein- protein folding is not random

1

Describe the features of the RNAase Refolding experiment?

1

How do we know the RNAase really was denatured during the experiment?

1

Which of the following are conditions for In Vitro Refolding (Like in the RNAase experiment)?

1

What type of amino acid is being shown ere?

1

Trans formations are less stable due to their steric hindrance

1

Proline is added to an amino acid chain exclusively in what form?

1

Which of the following proteins converts cis isomers to their trans form?

1

In the Cis form, the clash of functional groups around the alpha carbon is much greater due to steric hindrance

1

What type of bond is being shown here?

1

The previous amino acid to proline experiences steric hindrance in either proline conformation

1

Cis proline has _ energy than/to trans proline

1

The two cystine molecules that bind together are known as what?

1

Proteins with di-sulphide bonds are most likely to be found where?

1

Phosphorylation occurs on which residues?

1

Pro-sequences are found at the C-terminus

1

The Pro-sequence is also known as

1

Which proteins will have a pro-sequence?

1

The protein with a pro-sequence will auto-cleave it before folding correctly

1

What is co-operativity in protein folding?

1

What does the Hydrophobic Zipper Model suggest?
