The Enzyme Commission number (EC number) is a numerical classification scheme for enzymes, based on the chemical reactions they catalyze. As a system of enzyme nomenclature, every EC number is associated with a recommended name for the respective enzyme.
Strictly speaking, EC numbers do not specify enzymes, but enzyme-catalyzed reactions. If different enzymes (for instance from different organisms) catalyze the same reaction, then they receive the same EC number. By contrast, UniProt identifiers uniquely specify a protein by its amino acid sequence.

Famous quotes containing the words commission and/or number:
“Yesterday the Electoral Commission decided not to go behind the papers filed with the Vice-President in the case of Florida.... I read the arguments in the Congressional Record and can’t see how lawyers can differ on the question. But the decision is by a strictly party vote—eight Republicans against seven Democrats! It shows the strength of party ties.”
—Rutherford Birchard Hayes (1822–1893)
“Black lady,
what will I do
without your two flowers?
I have inhabited you, number by number.
I have pushed you in and out like a needle.”
—Anne Sexton (1928–1974)
