This invention refers to the obtainment of a modified lipolytic enzyme that was isolated, expressed and purified from the heterologous expression. The gene sequence that codifies for the basal enzyme was obtained based on a thermo acidophilus organism of the acidobacteraceae family. This basal enzyme that comes from a thermo acidophilus organism, it is able to hydrolyze lipid substrates (triacylglycerols) united to middle chain fatty acids (C.sub.6-C.sub.10) such as tributyrine and tricapryln, among others. It also can carry out other inverse reactions to the hydrolysis such as synthesis reactions. On the other hand, this enzyme has enantioselective preference on (S) substrates of profens esters such as ibuprofen, naproxen and others. The enantioselective lipolytic basal enzyme was modified in its terminal C end to add an amino acid histidine tail that gives a higher efficiency in its purification process. The invention therefore refers to a method for making a pure, active polypeptide, which is called lipolytic enzyme 499EST obtained through the host E. coli BL 21 (DE3).
