What does lanthionization involve?

  1. Converting a disulfide bond into two sulfide atoms

  2. Removing one of the sulfur atoms from a disulfide bond

  3. Adding an additional sulfur atom to a lanthionine bond

  4. None of the above

The correct answer is: Removing one of the sulfur atoms from a disulfide bond

Lanthionization involves the formation of a lanthionine bond by removing one of the sulfur atoms from a disulfide bond. This process does not involve converting a disulfide bond into two sulfide atoms (A) or adding an additional sulfur atom to a lanthionine bond (C). Option D is also incorrect as it does not provide a specific explanation of what lanthionization involves.
