Information About

Ec Number




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.


FORMAT OF NUMBER

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 Tripeptide Aminopeptidase s have the code "EC 3.4.11.4", whose components indicate the following groups of enzymes:

  • ''EC 3'' enzymes are Hydrolase 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'' are those hydrolases that cleave off the amino-terminal Amino Acid from a Polypeptide

  • ''EC 3.4.11.4'' are those that cleave off the amino-terminal end from a Tripeptide
