Protein Structure Pt. 1

1

Which type of protein is conjugated?

1

Which of the following means a protein with two identical subunits?

1

Which of the following proteins types tend to have various roles, as opposed to a single, defined one?

1

Which of the following tend not to be water soluble?

1

What secondary structures tend to make up fibrous proteins?

1

What is specific about the membrane spanning part of membrane proteins?

1

Define 'Domain' in reference to protein structure

1

Define subunit

1

What can be the result of a single amino acid mutation in collagen?

1

What is Resonance (as pertaining to protein structure)?

1

Which is the psi bond?

1

Which is the phi bond?

1

What is Steric clashing?

1

Why is a peptide bond planar?

1

How many residues per turn in an alpha helix?

1

How much does an alpha helix rise per aa?

1

Alpha helices are stabilised by hydrogen bonding with what groups?

1

The stabilising effect of the hydrogen bonds makes a loop of how many atoms?

1

Which of the following destabilize an alpha helix?

1

Beta sheets rise by 3.47A per residue in anti-parallel sheets

1

In parallel sheets, there is a rise of .... per residue

1

3 residues per turn of the strand are pictured as a helix

1

Anti-parallel strands are _ stable than parallel ones

1

Side chains all point the same way (in the plane of the sheet)

1

What is the role of loops?

1

Loops contain mostly hydrophillic residues & are found on the protein surface

1

What is the role of beta turns?

1

What two amino acids cannot be contained within a beta sheet?

1

Beta turns link the oxygen of the carbonyl group and the hydrogen of the nitrile group 4 residues away

1

Levinthals Paradox- if a protein folded by trying each fold in a sequence, it would take an impossibly long time to fold correctly. Therefore, protein folding cannot be random or sequential

1

What is this?

1

Why are the internal interactions of protein folding unfavorable?

1

Non-covalent and hydrophobic effects (which effects free water) decrease enthalpy
