## Map Between Enzyme Commission Numbers and Manufacturer Identifiers

### Description

hgu95dENZYME2PROBE is an R environment that maps Enzyme Commission (EC) numbers to manufacturer identifiers.

### Details

Each EC number maps to a named vector containing all of the manufacturer identifiers that correspond to the gene that produces that enzyme. The name of the vector corresponds to the EC number.

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 hgu95dENZYME2PROBE, 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(hgu95dENZYME2PROBE)
       if(length(xx) > 0){
           # Gets the probe identifiers for the first five enzyme
           #commission numbers
           xx[1:5]
           # Get the first one
           xx[[1]]
