Hofmeister Effect on Enzymatic Catalysis and Colloidal Structures

Bauduin, Pierre; Renoncourt, A; Touraud, Didier; Kunz, Werner; Ninham, Barry


An attempt is made to decouple the effects that occur when different electrolytes are added to proteins, especially enzymes, in buffer solutions. In particular, direct molecular 'chemical' interactions between ions and specific sites on the enzyme are distinguished from 'physical' interactions due to electrostatic and dispersion forces. The latter are often related to a Hofmeister series. It is shown that bulk effects, usually on the pH via a shift of the buffer equilibria, must be separated...[Show more]
