Origem, evolução e relações filogenéticas de homólogos de prolina racemase em espécies de Trypanosoma. / Origin, evolution and phylogenetic relationships of proline racemase homologs from species of Trypanosoma.

Espinosa, Zuleima Del Carmen Caballero 30 October 2014 (has links)
Os genes de Prolina racemase (PRACs) são enzimas intracelulares ou secretadas de T. cruzi (TcPRAC); essas enzimas estão envolvidas no metabolismo, diferenciação e virulência. Os genes PRAC foram identificados e caracterizados molecularmente em isolados representantes de toda a diversidade interespecífica de T. cruzi, T. cruzi marinkellei, T. dionisii, T. erneyi, T. rangeli, T. conorhini e T. lewisi. Além dessas espécies de tripanossomas restritas a mamíferos; homólogos de PRAC foram encontrados em tripanossomas de cobra (T. serpentis), crocodilo (T. grayi) e anuro (T. sp. 339). Análises filogenéticas e de sintenia entre homólogos de PRAC suportaram uma historia evolutiva totalmente congruente com as relações evolutivas previamente descritas dentro do gênero Trypanosoma. / Proline racemaces (PRACs) are intracellular or secreted enzymes of Trypanosoma cruzi (TcPRAC), implicated in metabolism, differentiation, virulence and the induction of nonspecific polyclonal B-lymphocyte in the host. We identified and molecularly characterized PRAC genes from isolates representing all intra-specific diversity (TcI-TcVI and Tcbat), T. cruzi marinkellei, T. dionisii, T. erneyi, T. rangeli (isolates of lineages A-E), T. conorhini, and T. lewisi. In addition to these trypanosome species restricted to mammals, PRAC homologs were found in trypanosomes from snake (T. serpentis), crocodile (T. grayi) and anuran (T. sp 339). Phylogenetic and synteny analysis of PRAC homologs supported an evolutionary history totally congruent with the evolutionary relationships within the genus Trypanosoma.
