Which of the following interactions hold the leucine zipper together?
A)H-bonds
B)hydrophobic interactions
C)ionic interactions
D)metal ion binding
E)protein:DNA interactions

Question

Quizplus · Accepted Answer

Leucine zipper is a protein structural motif consisting of a stretch of amino acids rich in leucine, which form an alpha-helix that dimerizes with another alpha-helix in an antiparallel manner to create a coiled-coil structure. The hydrophobic interactions between the leucine residues in the two alpha-helices are responsible for holding the leucine zipper together. H-bonds, ionic interactions, metal ion binding, and protein-DNA interactions are not involved in the stability of the leucine zipper.
