13. Protease gene shuffling and expression in Pichia pastoris
Four kinds of neutral and alkaline protease genes from Aspergillus oryzae and Bacillus subtilis were isolated and shuffled. The shuffled genes were selected, inserted into pGAPZαA plasmid and transformed into Escherichia coli. The gene which could express high-activity protease was selected by screening the sizes of transparent zones around the colonies on

14. Transcriptome analysis of resistant soybean roots infected by Meloidogyne javanica
Soybean is an important crop for Brazilian agribusiness. However, many factors can limit its production, especially root-knot nematode infection. Studies on the mechanisms employed by the resistant soybean genotypes to prevent infection by these nematodes are of great interest for breeders. For these reasons, the aim of this work is to characterize the trans

16. Theobroma cacao cystatins impair Moniliophthora perniciosa mycelial growth and are involved in postponing cell death symptoms.
Three cystatin open reading frames named TcCys1, TcCys2 and TcCys3 were identified in cDNA libraries from compatible interactions between Theobroma cacao (cacao) and Moniliophthora perniciosa. In addition, an ORF named TcCys4 was identified in the cDNA library of the incompatible interaction. The cDNAs encoded conceptual proteins with 209, 127, 124, and 205

17. CaracterizaÃÃo BioquÃmica Parcial do LÃtex de Cryptostegia grandiflora R. Br. e AÃÃo Contra o Vetor da Dengue. / Biochemical characterization of latex of Cryptostegia grandiflora and larvicidal activity against Aedes aegypti
Cryptostegia grandiflora R. Br. is a shurb belonging to Apocynaceae family popularly known as âunha de bruxaâ. There are few studies available about the latex from this species and preliminary assays had shown its action against Dengue vector. Thus, this study aimed to characterize the biochemical properties of Cr. grandiflora latex and to evaluate the act

18. Proteases de Leishmania: novos alvos para o desenvolvimento racional de fármacos
Leishmania causes tegumental and visceral diseases called leishmaniasis. Disease control is possible interrupting the transmission cycle, but HIV co-infection, chemotheraphy toxicity and lack of a vaccine are paramount difficulties. So, is necessary to study new Leishmania molecules and investigate the possibility to develop rational drugs using these molecu

19. Chemoenzymatic synthesis of organoselenium(IV) compounds and their evaluation as cysteine protease inhibitors
Uma série de organosselenanas foi sintetizada utilizando-se uma metodologia quimio-enzimática. Estas organosselenanas apresentam variações na estereoquímica e no halogênio ligado ao átomo de selênio. Devido à reação característica envolvendo compostos de selênio e tióis, estas organosselenanas foram avaliadas como inibidores de cisteíno protea

20. Back to the future in Chagas disease: from animal models to patient cohort studies, progress in immunopathogenesis research
Despite the wealth of information generated by trans-disciplinary research in Chagas disease, knowledge about its multifaceted pathogenesis is still fragmented. Here we review the body of experimental studies in animal models supporting the concept that persistent infection by Trypanosoma cruzi is crucial for the development of chronic myocarditis. Complemen

21. Partial purification and characterization of serine and cysteine proteases of Sitophilus zeamais (Coleoptera: Curculionidae) / Purificação e caracterização parciais de serino e cisteíno proteases de Sitophilus zeamais (Coleoptera: Curculionidae)
Serine and cysteine proteases of a susceptible and two resistant strain (one with a cost associated with resistance and other without cost) of the maize weevil Sitophilus zeamais were partially purified using an affinity column of aprotinin-agarose . The highest purification factor was obtained for the resistant no-cost strain, 51.20x, with a yield of 14.8%

22. Genes de cisteíno proteases (Catepsina L-like) de Trypanosoma rangeli: polimorfismo, relações filogenéticas e alvos para diagnóstico e genotipagem. / Cathepsin L-like genes of Trypanosoma rangeli: phylogenetic analysis and polymorphic sequences as markers for lineage genotyping and diagnosis.
Nós isolamos e seqüenciamos genes que codificam Catepsina L-like em diversos isolados de T.rangeli de humano, mamíferos silvestres e Rhodnius spp., do centro e sul da América. Análises filogenéticas de seqüências que codificam a proteína madura de T. rangeli, outras espécies de Trypanosoma e Leishmania e duas espécies de bodonídeos, posicionaram

23. ALT-C, a disintegrin-like Cys-rich protein from Bothrops alternatus, increases skeletal myoblast viability
ALT-C, an ECD motif (glutamic acid, cysteine, aspartic acid) disintegrin from Bothrops alternatus snake venom, induces α2β1 integrin-mediated signaling and neutrophil chemotaxis. In vitro, in human umbilical vein endothelial cells (HUVEC), ALT-C induces cell proliferation, thus showing an interesting potential for tissue regeneration studies. This work aim

24. Propriedades bioquímicas e cinético-enzimáticas de cisteíno- proteases do intestino médio da lagarta da soja / Biochemistry and kinectics-enzymatics properties of cysteine-proteases of the velvetbean caterpillar midgut
Protease inhibitors that react with insect specific proteases are candidates to have their genetic code inserted in genetically modified plants. The first step to achieve this is the characterization of proteolytic enzymes of these insects intestines. Cysteine-protease of the soluble and insoluble fractions from the midgut of Anticarsia gemmatalis were chara
