forces stabilizing quaternary structures Flashcards
(4 cards)
1
Q
How to hydrophobic interactions stabilize the quaternary structure?
A
subunits interface through hydrophobic regions to minimize exposure to aqueous environment, driven by entropy
2
Q
How do hydrogen bonds stabilize quaternary structure?
A
stabilizes interfaces between subunits
3
Q
How do ionic bonds stabilize quaternary structure?
A
can form between charged residues at interfaces of subunits
4
Q
How do disulfide bonds stabilize quaternary structure?
A
in some multi-subunit proteins, they can link different polypeptide chains
