Because Leishmania is a parasite with a heteroxenous life cycle, exposed to different temperatures both in the insect vector and in the mammalian host, we decided to evaluate the temperature range at which ENDOG mantains its activity and determined that this enzyme is active above 20[degrees]C, presenting peak activity at 40-46[degrees]C.
