| + | beta-Lactoglobulin, being one of the principal whey protein, is of huge importance to the food industry. Temperature/pressure effects on this small protein has been extensively studied by industry. To characterize biochemical properties of beta-lactoglobulin after or during pressurization, a wide range of methods have been used thus far. In this study, for the first time, the pressure-induced conformation of beta-lactoglobulin in the crystal state was determined, at pressure 430 MPa. Changes observed in the high pressure structure correlate with the physico-chemical properties of pressure-treated beta-lactoglobulin obtained from dynamic light scattering, electrophoretic mobility and quartz crystal microbalance with dissipation monitoring measurements. A comparison between the beta-lactoglobulin structures determined at both high and ambient pressure contrasts the stable nature of the protein core and adjacent loop fragments. At high pressure the beta-lactoglobulin structure presents early signs of dimer dissociation, charge and conformational changes characteristic for initial unfolded intermediate as well as a significant modification of the binding pocket volume. Those observations are supported by changes in zeta potential values and results in increase affinity of the beta-lactoglobulin adsorption onto gold surface. Observed pressure-induced structural modifications were previously suggested as an important factor contributing to beta-lactoglobulin denaturation process. Presented studies provide detailed analysis of pressure-associated structural changes influencing beta-lactoglobulin conformation and consequently its adsorption. | ||
