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.
Catalase (like many enzymes) has a specific function. This is because of the unique shape of the catalase molecule. Its shape allows the enzyme to bond with a specific substrate (such as hydrogen peroxide). A substrate is the compound with which an enzyme bonds. Think of it as a lock and key. In our example, catalase represents the lock, and the hydrogen peroxide represents the key.
