The Enzyme Commission number ('''EC number''') is a Numerical Classification scheme for Enzyme s, based on the Chemical Reaction s they Catalyze . As a system of enzyme nomenclature, every EC number is associated with a recommended name for the respective enzyme. Every enzyme code consists of the letters "EC" followed by four numbers separated by periods. Those numbers represent a progressively finer classification of the enzyme. For example, the enzyme s (enzymes that use Water to break up some other molecule), EC 3.4 are hydrolases that act on Peptide Bond s, EC 3.4.11 enzymes are only those hydrolases that cleave off the amino-terminal Amino Acid from a Polypeptide , and EC 3.4.11.4 are those that cleave off the amino-terminal end from a Tripeptide . |
