Which of the following is not a structural motif encountered in DNA-binding proteins?
A) helix-turn-helix
B) leucine zipper
C) zinc finger
D) β− barrel

Question

Quizplus · Accepted Answer

β-barrel is not a structural motif typically found in DNA-binding proteins. Instead, it is a structural motif found in various proteins, including some enzymes and transport proteins, but not typically in those that bind to DNA. The helix-turn-helix, leucine zipper, and zinc finger motifs are all common structural motifs in proteins that bind to DNA.
