The conjugation of polypeptidesfrom a designed set to the small molecule ligand 3,5-bis[[bis(2-pyridylmethyl)amino]methyl]benzoic acid, which in the presence of Zn2+ ions binds inorganic phosphate, has been shown to provide a polypeptide conjugate that binds α-casein, a multiply phosphorylated protein, with a dissociation constant KD of 17 nM. The measured affinity is more than three orders of magnitude
