WebThe tertiary structure is the further folding of a polypeptide to give a more complex 3D shape. The shape is very precise and specific to the function of the polypeptide. The quaternary structure of a protein is if it is made of two or more polypeptides. Haemoglobin is an example with a quaternary structure because it has four polypeptides. WebAustin Riggs from Harvard University was working on the blood disorder sickle cell anaemia, and he had discovered that introducing mercury atoms into haemoglobin did not affect its oxygen-carrying capacity. In other words the addition of mercury hadn’t changed the structure of haemoglobin. This was the breakthrough that Perutz needed.

WebReading: Protein Structure. As discussed earlier, the shape of a protein is critical to its function. For example, an enzyme can bind to a specific substrate at a site known as the active site. If this active site is altered because of local changes or changes in overall protein structure, the enzyme may be unable to bind to the substrate.
