| + | A number of studies were devoted to understanding an immunological effect of pressure-treated beta-lactoglobulin. In our previous work we have proved that high pressure significantly modifies beta-lactoglobulin conformation and consequently its physicochemical properties. Here, structure of beta-lactoglobulin complex with myristic acid determined at the highest accepted by the crystal pressure value of 550MPa is reported. Our results structurally prove that pressure noticeably modifies positions of the major beta-lactoglobulin epitopes. Considering the biological impact of observed changes in epitope regions, high pressure beta-lactoglobulin structure presents a step forward in understanding the pressure modification of food protein allergenicity. The conformational changes of pressurized beta-lactoglobulin did not support the hypothesis that proteolytic digestion facilitated by pressure is caused by an exposure of the digestive sites. Our findings demonstrate that high pressure protein crystallography can potentially identify the most pressure-sensitive fragments in allergens, and can therefore support development of hypoallergenic food products. | ||
