Enzyme Commission (EC)

The Enzyme Commission (EC) is a hierarchical system that classifies enzymes, which are biological catalysts that speed up chemical reactions in living organisms. Each enzyme is assigned a unique four-part number (like EC 3.1.4.11) based on the specific type of reaction it catalyzes. This classification helps scientists understand and organize enzymes according to their functions. For example, EC numbers differentiate between enzymes that break down proteins, synthesize DNA, or convert sugars. This standardized system is essential for researchers studying biochemistry, medicine, and biotechnology to communicate clearly about enzyme activities.
