Question

The Greek key is associated with which of the following?
A) $\alpha$-helix
B) Parallel $\beta$-pleated sheets
C) Antiparallel $\beta$-pleated sheets
D) Disulfide bridges
E) Salt bridges

Accepted Answer

The Greek key motif is a type of secondary structure pattern found in proteins, specifically associated with antiparallel β-pleated sheets. This motif involves the arrangement of β-strands in a way that resembles the geometric pattern known as the Greek key, contributing to the stability and folding of the protein structure.
