Effect of Organic Solvents on Porcine Pancreatic Lipase Thermal Aggregation.
Protein and Peptide Letters 2017 July 25
Proteins tend to form inactive aggregates under harsh conditions used in industrial processes. Lipases are enzymes that hydrolyze triglycerides to glycerol and free fatty acids, but are able to catalyze various other transformations in the presence of organic solvents. Considering this potential, a study on lipases behavior at high temperature and in presence of organic solvents is appropriate. Heat-induced aggregation of porcine pancreatic lipase (PPL) was followed by UV-visible spectroscopy at 400 nm wavelength for 600 seconds, at the isoelectric point (pH 5, phosphate solution) and 50°C, and in presence or absence of various percentages of dimethyl sulfoxide (DMSO), propanol, isopropanol, acetone and trifluoroethanol (TFE). Possible positioning of each organic solvent molecule relative to PPL was investigated using docking method. Native enzyme aggregated under aforementioned conditions and amorphous aggregates formed which were visible to the naked eye. From the tested solvents, DMSO reduced protein aggregation in a concentration-dependent manner. On the other hand, the protein aggregation intensified by adding any of propanol, isopropanol, acetone or TFE. This effect was more pronounced in TFE and propanol compared to isopropanol and acetone. In conclusion, DMSO could be effectively used to counteract lipase aggregation.
