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

_D_e_t_a_i_l_s:

     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 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 <URL:
