Disclosed is a method for enhancing the effect of a protein modulator on a protein by modifying the protein modulator so that the protein modulator binds with the surface of the protein, along with a method for modulating a protein's biological function by contacting the protein with such a modified protein modulator. Also described are modified protein modulators having the formula PM-SP-(LK)
p
-MCG-(M)
q
, where PM is a protein modulator which interacts with an active site or allosteric site of a protein; SP is a spacer; LK is a linker; p is 0 or 1; q is an integer greater than or equal to one; MCG is a metal chelating group; and M is a metal ion.
