Which of the following is a highly compact structure that is very commonly used to transition from one region of secondary structure to another in a globular protein?
A)$\alpha$ bend
B)$\beta$ turn
C)$\alpha$/$\beta$ hairpin
D)high-glycine loop
E)none of the above

Question

Quizplus · Accepted Answer

A β-turn is a highly compact structure commonly used to transition from one region of secondary structure to another in a globular protein. It consists of four amino acid residues arranged in a tight turn, with the first and fourth residues often being glycine or proline. This structure allows the polypeptide chain to reverse direction and fold back on itself, which is necessary for the formation of compact globular proteins. Choice A and C are not specific enough and can be eliminated. Choice D, high-glycine loop, is not a commonly used term for a specific structural element. Therefore, B is the best choice for this question.
