     ygs98ENZYME2PROBE is an R object that maps Enzyme Commission (EC)
     numbers to manufacturer identifiers.

_D_e_t_a_i_l_s:

     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 <URL: 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 ygs98ENZYME2PROBE, 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 <URL:

     Mappings were based on data provided by: KEGG GENOME (
