How do silent mutations affect a protein

WebMay 17, 2024 · The structure of a protein is very important to the function of the protein. There are many forces that drive the structure of a protein, including: electrostatic forces, hydrogen bonding, hydrophobic forces, and disulfide bonds. External forces like temperature and pH can also alter the structure of a protein; this is called denaturation.
