Biomolecules

Name the class of enzyme that usually catalyses the following reaction:

where G → a group other than hydrogen, S → a substrate, S# → another substrate.

  1. A.Hydrolase
  2. B.Lyase
  3. C.Transferase
  4. D.Ligase

Solution

Moving a group G from one substrate to another is the signature of a transferase. Hydrolases add water, lyases remove groups to form double bonds, and ligases join two molecules with ATP.
