Stability and activity of enzymes observed in aqueous solutions. A detailed analysis of dependence of enzyme stability or activity and Hofmeister effect will be given as few case studies later in Ibis chapter. 

The activity and stability of mushroom tyrosinase in [BMIM] containing ILs were analyzed in detail with respect to the influence of Hofmeister effect of the anions on the catalytic performance of the enzyme and active site structure as well as reaction mechanism [120]. Enzyme activity was in the opposite order to that of the Hofmeister series [BMIM][PFg]>[BMIM][BF ]>[BMIM][MeSO ] which was attributed to the more influential kosmotropic effect of the cation [121].

Bostrom et al. emphasized the importance of dispersion forces regarding the specific ion effects on proteins and also regarding non protein-related Hofmeister effects. The charge on the protein lysozyme depends on the anion in salt solutions (Bostrom et al. 2003a), but only Cl and SCN (as their potassium salts) are compared. Phos-phatidylglycerol bilayers (Bostrom et al. 2006a) are affected by Cl , Br , and SCN (as their sodium salts) in this order. Even silica membranes show Hofmeister series effects, namely in pH measurements with a glass electrode in fairly concentrated...

These effects were felt to be consistent with nonstoichiometric, double-layer ion-pairing models [6] and the rank of the anion in the Hofmeister series. Although the Hofmeister effect is not completely understood, it is well accepted that the rank of an ion in the series is a measure of its propensity to accumulate at or near interfacial regions and that the physical quantity responsible for the effect is intimately tied to the solvation properties of the ion.
