Weak interactions among amino acids that stabilize the tertiary structure of the protein include (list five):

Expert Solution

1. Vanderwaal force - It is a attractive and repulsion forces between two molecules due to fluctuations in the electron density of those molecules.

2. Hydrogen Bonds - It is a bond between highly electronegative molecule such as oxygen, fluoride or nitrogen with the partially positive hydrogen atom. Polar amino acids generally form hydrogen bonds

3. Ionic interaction - Interaction between oppositely charged side chains of amino acids is called ionic interaction

4. Hydrophobic Interactions- This interaction is between the water molecules and nonpolar amino acids. The side chains of these less soluble amino acids is buried in the core in tertiary structure to minimize the contact with water.

5. Dipole - dipole interactions - It is the attractive interaction between partially charged groups of amino acids. The partially charged positive group interacts with partially negative group of amino acid.

List the stabilizing forces at tertiary level of protein structure. An enzyme containing the amino aspartic acid (pKa of the side chain = 3.65) and histidine (pKa of the side chain= 6) in the active (catalytic ) site has an optimal activity at a pH of 5.0. What is the major stabilizing force at the catalytic site? Using structures and 1-3 complete sentences, predict and explain what is expected to happen to the activity if the pH is increased to...
