Leishmaniasis, a neglected tropical disease, is a major cause of morbidity and mortality worldwide. Of the three main clinical forms, cutaneous leishmaniasis (CL) is the most common and 40 million people are at risk in the endemic areas. Currently, the available drugs to fight leishmaniasis have high toxicity and poor efficiency. Then, it is very important to search for effective and safe drugs that would target essential enzymes from the parasite, such as lanosterol 14-alpha demethylase (CYP51, EC 1.14.13.70) from Leishmania braziliensis. Because most drug design efforts have been directed for Leishmania non-braziliensis species, there is no structural or kinetic data regarding L. braziliensis CYP51. Herein, we present for the first time molecular biology efforts and purification protocol to obtain the enzyme LbCYP51. These results lay the ground for future investigation of drugs against this target.
