CPC Definition - Subclass C12Y
This place covers:
Enzymes of which the EC number is known.
In this subclass, each enzyme is classified according to their EC number of the "Enzyme Nomenclature" (as valid on 1 January 2013) recommended by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.The EC number appears in the subgroups within parentheses and is reflected in the classification symbol: the EC number with the notation a.bb.cc.ddd is rendered into a CPC symbol C12Y ABB/CCDDD (with no trailing zeroes at the end) where:
EC a.bb.cc.ddd | CPC symbol |
a ranges from 1-6 | A = 1-6 |
b ranges from 1-99(*) | B = 01-99 |
c ranges from 1-99(*) | C = 01-99 |
d ranges from 1-400(*) | D = 001-400 |
(*) not all numbers are used
Examples: Alcohol dehydrogenase: EC 1.1.1.1.--------C12Y 101/01001
Togavirin: EC 3.4.21.90------C12Y 304/2109
Hepsin: EC 3.4.21.106-----C12Y 304/21106
Cobaltochelatase EC 6.6.1.2----------C12Y 606/01002

- This subclass is for discretionary supplementary classification of subject matter already classified as such in other classification places like the ones above.
- Rules for use of C12Y together with any of the subgroups above are specific for each subgroup and can be found with the relevant subgroup.
