Selenocysteine in Trypanosoma evansi: Identification of the Genes selb, selc, seld, pstk, seltryp and the Selenophosphate Synthetase Protein

Selenoproteins have been described in all three domains of life and their function has mainly associated with oxidative stress defense. Canonical elements required for selenoprotein production identified members the kinetoplastid group supporting existence a complete selenocysteine synthesis pathway these organisms. Currently, nothing is known regarding Trypanosoma evansi. In this study, we expression selB, selC, selD, PSTK selTRYP at mRNA level T. All translated proteins (selD, PSTK, selB) predicted higher identity brucei. gambiense. The selenophosphate synthetase protein was localized cytoplasm. Our results support an active
