Detergents as probes of hydrophobic binding cavities in serum albumin and other water-soluble proteins.

Abstract

As an extension of our studies on the interaction of detergents with membranes and membrane proteins, we have investigated their binding to water-soluble proteins. Anionic aliphatic compounds (dodecanoate and dodecylsulfate) were bound to serum albumin with high affinity at nine sites; related nonionic detergents (C12E8 and dodecylmaltoside) were bound at… (More)
