Abstract
The degree of enzyme deactivation for lipases from Candida rugosa and Pseudomonas sp., hydroxynitrile lyase and mandelate racemase upon exposure to organic solvents can be correlated to their respective partition coefficients (log P values). However, three unexpected results were obtained: (1) the deactivation exerted by protic solvents, e.g., methanol, is severely underestimated; (2) little deactivation by an organic solvent cannot neccessarily be correlated to catalytic activity in this medium, and (3) in contrast to other enzymes, hydroxynitrile lyase is exceptionally stable towards deactivation by DMF.
