Tertiary structures of proteins Flashcards
1
Q
What are loops containing only a few (up to five) residues referred to as?
A
Turns
They are also called turns because they connect different secondary structures such as helices or strands.
2
Q
What are the two common types of ß turns?
A
Type I and Type II
Both types of turn contain four amino acid residues and are stabilized by hydrogen bonding.
3
Q
What is an important feature of tertiary structure?
A
Bringing together amino acid residues that are far apart in the primary structure
This allows interactions among their side chains.
