WebNov 7, 2024 · Enzymes are made up of 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 acid in the protein is encoded by the DNA sequence of the corresponding gene. WebThe tertiary structure of an enzyme determines the structure of its active site, and therefore its substrate binding ability. Mutations can disrupt enzymes. Mutations in the DNA of an organism can lead to the development of proteins and enzymes with mutations. These mutations can cause a protein or enzyme to lose its intended function.
