Question

In a helix-turn-helix motif in proteins, which one of tyhe following is true for binding to nucleic acids?

Options

Choose one · Correct answer highlighted

Both the helices bind Neither of the two helices bind Only the 1st helix is important in binding The 2nd helix is important in binding Correct

Explanation

The principle of enzyme catalysis and lipid structure explains that substrate affinity, transition state stabilization and phospholipid composition govern function. Hence The 2nd helix is important in binding fits best because it reflects catalytic efficiency and membrane organization, as documented in authoritative sources on biochemistry.
