Hydrophobic Interactions in Purification and Utilization of Enzymes

  • Wayne Melander

The importance of the hydrophobic effect in biochemical systems has been widely recognized since Kauzmann (1) enunciated its role in determining the threedimensional structure of proteins. The strength of hydrophobic interactions is commensurate with that of hydrogen binding and ionic effects in a typical protein (2). Numerous authors have looked for a quantitative ranking for the hydrophobic character of amino acid side chains to estimate the hydrophobicity of proteins (3–6). One theory attributed the large entropy effect to changes in the hydrogen bonding structure of water in the vicinity of solute molecules(7–10); while another found the free energy of hydrocarbons in water to be proportional to the number of solvent molecules surrounding the solute and also to the solute surface area as determined from molecular models (11–14).
