WebOct 4, 2024 · They can turn enzymes on or off, acting as activators or inhibitors, respectively. In addition, enzymes can be regulated via covalent modification or post-translational modification. That means that, after the enzyme has been assembled in the cell, its structure can be modified further by adding special groups to specific locations.
