“…For example, compact protein substrates tend to resist proteolysis, whereas unfolded or partially unfolded proteins are generally more susceptible to proteolytic degradation (Daniel et al, 1982;Markert et al, 2001). The protein bovine serum albumin (BSA) studied here, interacts with a number of surfactants including alkyl sulfates, alkyl sulfonates, and trimethylammonium bromides (Kaneshina et al, 1973;Reynolds et al, 1967) to induce conformational change (Gelamo and Tabak, 2000;Lu et al, 2005Lu et al, , 2006. Likewise, partial unfolding of enzymes due to surfactant generally results in loss of enzymatic activity (Cruzten and Douglas, 1999;Stoner et al, 2004).…”
