Trypanosoma cruzi, Trypanosma brucei and Leishmaniaspp. are kinetoplastid protozoa causative agents of Chagas disease, sleeping sickness and leishmaniasis, respectively, neglected tropical diseases estimated to infect millions of people worldwide. Their genome sequencing has revealed approximately 50 % of genes encoding hypothetical proteins of unknown function, opening possibilities for novel target identification and drug discovery. Q4DY78 is a putative essential protein from T. cruzi conserved in the related kinetoplastids and divergent from mammalian host proteins. Here we report the 1H, 15N, and 13C chemical shift assignments and secondary structure analysis of the Q4DY78 protein as basis for NMR structure determination, functional analysis and drug screening.
