Enzyme inhibitors are molecules that interfere with the enzyme's activity. They can be classified as:
1. Competitive Inhibitors: Bind to the active site, preventing substrate binding. 2. Non-Competitive Inhibitors: Bind to an allosteric site, altering the enzyme's conformation and reducing its activity. 3. Uncompetitive Inhibitors: Bind only to the enzyme-substrate complex, preventing the reaction from proceeding.
Inhibitors are crucial in the regulation of enzymatic activity and are often used in drug design to target specific enzymes involved in diseases.
