the temperature and frequency dependence of the proton relaxation rates ( prr ) of the respective enzyme-mn-ligand complexes demonstrates that the perturbation of the electronic environment at the mn ( ii ) site on the enzyme is different upon binding of the inhibitor ( e-f-p-enolpyruvate ) in contrast to the binding of substrates ( p-enolpyruvate or z-f-p-enolpyruvate ) .
