The data presented here is related to negative results obtained with the recombinant expression of chitinase from four species of Leishmania parasites in two expression systems, performed in order to investigate the molecular characteristics of the Leishmania chitinase and its possible application in leishmaniasis diagnosis. Thus, heterologous Leishmania sp chitinase proteins were expressed in bacteria using the prokaryotic expression vector pET28a and Escherichia coli Mach-T1, and in Spodoptera frugiperda (Sf9) insect cells, using the eukaryotic bac-to-bac expression system (Thermo Fisher Scientific) to produce recombinant baculoviruses to infect Sf9. Biochemical and cellular analysis of the various recombinant forms of the Leishmania sp chitinase produced in prokaryotic and eukaryotic expression systems were performed through SDS-PAGE and Western blotting. Chitinase produced and purified from bacteria presented low yield and formed inactive aggregates. Heterologous chitinase obtained after infection of Sf9 insect cells with all the four Leishmania species recombinant baculoviruses presented high yield of insoluble proteins. Dot-blot serological tests presented inconclusive results against the recombinant Leishmania sp chitinases produced in both expression systems. The experiments described in this paper can help researchers to avoid errors when choosing a recombinant expression systems to produce Leishmania parasites proteins for biotechnological purposes. |
