Enzyme Activity

Assays Enzyme activity assays are tests used to measure an enzyme's activity in a sample. They measure the rate at which a substrate is converted to a product by an enzyme-catalyzed reaction, providing information on the enzyme's function and regulation. They are important in biochemistry, as they are often used to identify and quantitatively measure the activity of enzymes in tissues and fluids, to detect mutations in genes that lead to changes in enzyme activity, and to evaluate the effectiveness of drugs on enzymes. Enzyme activity assays can also be used to study the structure and function of enzymes, assess the efficiency of purification steps, and develop new enzyme-related products.
