Question

A new drug is developed which selectively cleaves covalent bonds between two sulfur atoms of non-adjacent amino acids in a polypeptide chain. Which level of protein structure in affected molecules would be most directly affected by the drug

Answer 1

Answer:

A new drug is developed which selectively cleaves covalent bonds between two sulfur atoms of non-adjacent amino acids in a polypeptide chain.

Answer 2

Answer:

The tertiary structure of the protein would be most directly affected by the medicine.

Explanation:

Cystine produces a disulfide bridge, which is formed when two cysteine molecules are joined by covalent bonds. The residues are normally 5 to 6 residues apart.

As a result, when a novel medication is being developed selectively cleaves covalent connections between non-adjacent sulfur atoms in a polypeptide chain, it cleaves the primary interaction sustaining the Tertiary structure which is the disulfide bridge. As a result, this medicine affects the tertiary structure of the protein.
