Nuclear magnetic resonance studies of the structure and binding sites of enzymes. XII. A conformational equilibrium in staphylococcal nuclease involving a histidine residue.
Evidence is presented for the existence of a conformational equilibrium in staphylococcal nuclease, involving one out of the four histidines and none of the other aromatic residues in the polypeptide chain.
