WebThe term holoenzyme refers to an apoenzyme that is complete and catalytically active, as well as the cofactor. A cofactor might be a tiny organic molecule or a metal ion. The majority of metal ions are covalently or noncovalently linked to the enzyme. Prosthetic groupings are what they’re called. Coenzymes are a type of small chemical molecule. bucs minicampWebThe holoenzyme subunits Srb4 and Kin28 were also found not to be essential for CUP1 transcription.
