Enzymes are made up of Î±n amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acids in the protein is encoded by the DNA sequence of the corresponding gene. Click here for a list of all 21 amino acids.
Enzymes are structured so that they bond to a second, specific molecule, called a substrate. When the enzyme and its substrate come together, at a place on the enzyme called the active site, the substrate is modified, for example by combining two different substrate molecules into a single molecule.oun. 1. enzyme-any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions. active site-the part of an enzyme or antibody where the chemical reaction occurs.
