     hgu133aENZYME mappes probe ids to enzyme commission numbers
     corresponding to the products of the genes represended by the
     probe ids

_D_e_t_a_i_l_s:

     This is an environment object with key and value pairs. Keys are
     probe ids and values are the corresponding enzyme commission
     numbers. Values are vectors of length 1 or greater depending on
     whether a given probe id can be associated with only one or more
     enzyme commission numbers.

     NAs are assigned to probe identifiers that can not be associated
     with any enzyme commission numbers. Mappings between probe ids and
     enzyme ids were obtained through their mappings to LocusLink ids.

     Mappings between probe ids and enzyme ids were obtained using
     files provided by:
