Enzyme Commission (EC) Numbers

Enzyme Commission (EC) Numbers are a systematic way to classify enzymes based on the chemical reactions they facilitate. Each enzyme is assigned a unique four-part code (e.g., 1.1.1.1) that indicates its specific function and the type of reaction it catalyzes. This classification helps scientists organize and understand the vast diversity of enzymes in biological systems. The first digit indicates the general type of reaction, while subsequent digits specify the enzyme’s particular activity, providing a precise, standardized reference for identifying and studying enzymes across different organisms.
