    摘要： The primary objective of the present invention is the development of new mutant forms of the Sm14 protein, for producing a greater production volume. The recombinant proteins here obtained were capable of providing protection against schistosome and fasciola infection. The level of protection of Sm14 recombinant proteins obtained in the present invention was similar to that reached in the parasite saline extract. The mutant proteins of the present invention have reached approximately 100% of renaturation after the heating at 80° C., different from wild forms of the Sm14 protein. Moreover, after storage for 2 months at 4° C., mutant proteins have shown smaller β-structure loss than wild forms that have shown formation with random structure, as demonstrated by the circular dichroism analysis, indicating the success of mutations.
