Which enzyme is not a protein?

Posted February 10, 2023


Answer

Ribozyme is the only enzyme that’s not a protein. Proteins are polypeptides of amino acid residues joined by peptide bonds. They make up the basic constituent of enzymes, which are catalytic compounds that affect the rate of biological reactions. The majority of enzymes are proteins. Ribozyme is an RNA- based enzyme that acts as a catalyst during protein synthesis. RNase P is a widely used ribozyme.
