Enzyme Commission number - Wikipedia, the free encyclopedia. The Enzyme Commission number (EC number) is a numerical classification scheme for enzymes, based on the chemical reactions they catalyze. If different enzymes (for instance from different organisms) catalyze the same reaction, then they receive the same EC number. Those numbers represent a progressively finer classification of the enzyme. Recommendations (1972) Supplement 1: Corrections and Additions (1975) Article first published online.

Enzyme, and finally the product is released, thus allowing the enzyme to start all over again (see right) An example is the action of the enzyme sucrase hydrolysing sucrose into glucose and fructose (see left) 2. Preliminary EC numbers exist and have an 'n' as part of the fourth (serial) digit (e. The group may be methyl- , acyl- , amino- or phosphate group. AB + C .
