Pore-forming toxins solve the problem of a need to provide hydrogen-bonding partners for the polypeptide background N-H and C=O groups in the bilayer that lacks hydrogen-bond donors and acceptors.Which of the following structure(s)do they use extensively to do this?

Question

Quizplus · Accepted Answer

Pore-forming toxins use α-helices and β-sheets extensively to provide the necessary hydrogen-bonding partners for the polypeptide background N-H and C=O groups in the bilayer. These secondary structures are stabilized by hydrogen bonds between backbone atoms, allowing the protein to form a stable and structured pore within the membrane.
