                              the synthetic D-enzyme has a D-amino acid residue sequence                                           
                              consisting of D-amino acids and glycine that defines a D-polypeptide                                 
                              able to catalyze a first enzymatic reaction corresponding to a second                                
                              enzymatic reaction catalyzed by the natural enzyme,
