The complete genome sequence of Chromobacterium violaceum reveals remarkable an...
Vasconcelos, Ana Tereza; De-Almeida, Darcy Fontoura; Hungría, Mariangela; Guimarães, Cláudia Teixeira; Antônio, Regina VasconcellosChromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spre...
Hemoglobin Uptake by Paracoccidioides spp. Is Receptor-Mediated
Bailão, Elisa Flávia Luiz Cardoso; Parente, Juliana Alves; Pigosso, Laurine Lacerda; Castro, Kelly Pacheco de; Fonseca, Fernanda LopesIron is essential for the proliferation of fungal pathogens during infection. The availability of iron is limited due to its association with host proteins. Fungal pathogens have evolved different mechanisms to acquire iron from host; however, little is known regarding how Paracoccidioides species incorporate and metabolize this ion. In this work, host iron sources that are used by Paracoccidioides spp. were in...

A secreted serine protease of Paracoccidioides brasiliensis and its interaction...
Parente, Juliana Alves; Salem-Izacc, Sílvia Maria; Santana, Jaime Martins de; Pereira, Maristela; Borges, Clayton Luiz; Bailão, Alexandre MeloBackground Paracoccidioides brasiliensis is a thermodimorphic fungus, the causative agent of paracoccidioidomycosis (PCM). Serine proteases are widely distributed and this class of peptidase has been related to pathogenesis and nitrogen starvation in pathogenic fungi. Results A cDNA (Pbsp) encoding a secreted serine protease (PbSP), was isolated from a cDNA library constructed with RNAs of fungal yeast cells re...
Rastreamento de ESTs, expressão heteróloga de cDNAs e análise de proteases no e...
Parente, Juliana AlvesTese (doutorado)—Universidade de Brasília, Faculdade de Medicina, 2009.; Paracoccidioides brasiliensis é um fungo patogênico humano, agente etiológico da paracoccidioidomicose (PCM). P. brasiliensis apresenta dimorfismo térmico, apresentando-se sob a forma miceliana a temperaturas inferiores a 28 ºC e sob a forma leveduriforme no hospedeiro humano e em temperaturas superiores à 28 ºC. Proteases são enzimas que ...
Molecular characterization of the NSP4 gene of human group A rotavirus samples ...
Tavares, Talissa de Moraes; Brito, Wilia Marta Elsner Diederichsen de; Fiaccadori, Fabíola Souza; Freitas, Erika Regina Leal de; Parente, Juliana AlvesNonstructural protein 4 (NSP4), encoded by group A rotavirus genome segment 10, is a multifunctional protein and the first recognized virus-encoded enterotoxin. The NSP4 gene has been sequenced, and five distinct genetic groups have been described: genotypes A-E. NSP4 genotypes A, B, and C have been detected in humans. In this study, the NSP4-encoding gene of human rotavirus strains of different G and P genotyp...
