Enzyme Structure
An enzyme is a large protein molecule that catalyzes biochemical reactions in an organism. It works by binding to a substrate and converting it into a product, thus speeding up the rate of the reaction. Enzymes are essential components of all cellular life, and they play an important role in metabolic activities. The structure of an enzyme is critical in determining its function; the shape of the active site allows certain substrates to bind to it, while excluding others. Knowing the structure of an enzyme enables researchers to understand its role in a biochemical process, and design drugs that can inhibit or activate its activity. In addition, researchers can design new enzymes or modify existing ones to perform new tasks or become more efficient in their existing roles.
