## Mappings between Enzyme Commission numbers and probe identifiers

### Description

hgu2beta7ENZYME2PROBE maps Enzyme Commission numbers to probe identifiers representing genes whose products exhibit the functions of the enzymes labeled by the Commission Numbers

### Details

Enzyme Commission numbers are assigned by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology http://www.chem.qmw.ac.uk/iubmb/enzyme/ to allow enzymes to be identified.

An Enzyme Commission number is of the format EC x.y.z.w, where x, y, z, and w are numeric numbers. In hgu2beta7ENZYME2PROBE, EC is dropped from the Enzyme Commission numbers.

Enzyme Commission numbers have corresponding names that describe the functions of enzymes in such a way that EC x is a more general description than EC x.y that in turn is a more general description than EC x.y.z. The top level EC numbers and names are listed below:

EC 1 oxidoreductases

EC 2 transferases

EC 3 hydrolases

EC 4 lyases

EC 5 isomerases

EC 6 ligases

The EC name for a given EC number can be viewed at http://www.chem.qmul.ac.uk/iupac/jcbn/index.html#6

        # Convert to a list
        xx <- as.list(hgu2beta7ENZYME2PROBE)
       if(length(xx) > 0){
           # Gets the probe ids for the first five enzyme
           #commission numbers
           xx[1:5]
           # Get the first one
           xx[[1]]
        }
