Our research focuses on the structure, function and evolution of large macromolecular complexes in mitochondria of the parasitic protist Trypanosoma brucei. ATP synthase In T. brucei, the mitochondrial ATP synthase switches from the ATP producer in the insect life cycle stage to the ATP consumer maintaing the essential potential on the inner mitochondrial membrane in the infectious mammalian bloodstream form. This unique functional adaptation is accompanied by highly divergent structure. We combine structural and functional approaches to get insight into the role of ATP synthase in trypanosomal bioenergetics and mitochondrial morphology during the life cycle. Ribosomes, highly conserved machines fundamental for all life forms, were recently shown to undergo unexpected diversification in endosymbiotic organelles with vestigial genomes. The most divergent ribosomes are found in the mitochondria of parasitic protists from the group of Kinetoplastids, including trypanosomes. We complement the wealth of structural information on mitoribosomes and their precursors obtained by cryoEM with functional approaches to get detailed insight into lineage specific features of translation in mitochondria of trypanosomes. We aim to understand how the divergent mitoribosomes co-evolved with the peculiar context of the mitochondrial gene expression in the parasite. 2013 - present Postdoctoral associate, Institute of Parasitology, Biology Centre ASCR, Ceske Budejovice (Dr. A.
