1. Proteomic analysis of excretory-secretory products from young adults of Angiostrongylus cantonensis
BACKGROUND Angiostrongyliasis is caused by the nematode Angiostrongylus cantonensis and can lead to eosinophilic meningitis and meningoencephalitis in humans. The young adult worms play central pathogenic roles in the central nervous system (CNS); however, the underlying mechanism is unclear. Excretory-secretory products (ESPs) are good investigation targe

2. Screening and selection of wild strains for L-arabinose isomerase production
The majority of L-arabinose isomerases have been isolated by recombinant techniques, but this methodology implies a reduced technological application. For this reason, 29 bacterial strains, some of them previously characterized as L-arabinose isomerase producers, were assayed as L-arabinose fermenting strains by employing conveniently designed culture media

3. Structural and biophysical studies of xylose isomerases for production of second generation ethanol / Estudos biofísicos e estruturais de xilose isomerases para produção de etanol de segunda geração
A demanda por combustíveis baseados em recursos renováveis é alta nos dias de hoje e tende a aumentar bastante no futuro. No Brasil, indústrias de biocombustíveis produzem principalmente etanol a partir cana-de-açúcar. A biomassa lignocelulósica, compreendendo resíduos de culturas, resíduos florestais, sólidos urbanos, é explorada como um elevado

4. Isoenzymatic variability in wild potatoes.
Two species of wild potato Solanum commersonii, subspecies commersonii and malmeanum, and S. chacoense, subspecies muelleri occur in southern Brazil. Their rusticity and easy adaptation to extreme climatic conditions make them valuable for breeding programs. The objective of this work was to analyze the isoenzymatic variability of 113 clones of wild potato s

5. Structural studies of the proteins Q4DV70 from Trypanosoma cruzi and mesothelin from Homo sapiens / Estudos estruturais das proteinas Q4DV70 de Trypanosoma cruzi e mesotelina de Homo sapiens
In this work we carried out studies with two proteins, Q4DV70 from Trypanosoma cruzi and mesothelin from Homo sapiens. The aim was to help the understanding of the function of these proteins which possibly are important to Chagas disease and cancer, respectively. Q4DV70 protein was annotated in T. cruzi genome as a conserved hypothetical protein. In our stud

6. Metaproteomic and biochemistry hydrocarbons and heavy metals-contaminated soils / Metaproteomica e bioquimica de solos contaminados por hidrocarbonetos e metais pesados
Hydrocarbons, heavy metals and agricultural defensives are high risk pollutants to human health. These pollutants are constantly introduced into the environment as a result of petrochemical, industrial, agricultural activities and our modern life style, requiring remediation processes that are used to their complete elimination. Bioremediation is a process c

7. In silico differential display of defense-related expressed sequence tags from sugarcane tissues infected with diazotrophic endophytes
Os padrões de expressão de 277 contíguos de ESTs de cana-de-açúcar codificando proteínas possivelmente associadas ao sistema de defesa vegetal, e.g. quitinases, beta-1,3- glucanases, fenilalanina amonia liases, chalcona sintases, chalcona isomerases, isoflavona redutases, glicoproteínas ricas em hidroxiprolina, glicoproteínas ricas em prolina, peroxi

8. Crystal structure of enzyme glucosamine-6-phosphate deaminase de E. coli K12 and its complexes with allosteric activator and inhibitor / Determinação da estrutura cristalográfica da enzima da Glucosamina-6-fosfato desaminase de E.coli K12 e seus complexos com ativador alostérico e inibidor
A enzima Glucosamina-6-fosfato desaminase (GlcN6P desaminase) é envolvida na conversão reversível da D-glucosamina-6-fosfato (GlcN6P) em Fru6P e amônia, como parte do caminho metabólico de aminoaçúcares como fonte de energia celular. A enzima hexamérica (peso mol. 178200) exibe uma cooperatividade homotrópica intensa em direção à GlcN6P a qual é

9. Pentose metabolism in Mycobacterium smegmatis: specificity of induction of pentose isomerases.
The induction of D-xylose, D-ribose, L-arabinose, and D-lyxose isomerases by various sugars was studied to determine the configuration necessary for induction. D-Xylose isomerase was only induced by D-xylose, whereas D-ribose isomerase was induced by D-ribose, L-rhamnose, and L-lyxose. L-arabinose isomerase was induced by L-arabinose, D-galactose, L-arabitol

10. Multiple Forms of Glucosephosphate Isomerase in Maize 12
Three apparently different glucosephosphate isomerases are found in the developing seeds of maize (Zea mays L.). Glucosephosphate isomerase I is found in both the endosperm and embryo. It is separable by column chromatography from glucosephosphate isomerase II of the developing endosperm and glucosephosphate isomerase III of the developing embryo and is furt

11. Pentose metabolism in Mycobacterium smegmatis: comparison of L-arabinose isomerases induced by L-arabinose and D-galactose.
D-Galactose, which did not serve as a growth substrate, was found to induce an L-arabinose isomerase of similar properties to the L-arabinose-induced L-arabinose isomerase. In both cases the pH profiles, pH stability, optimum temperature, heat stability, substrate specificity, metal ion requirements, mobility on polyacrylamide gel electrophoresis, and kineti

12. Peptidyl-prolyl isomerases: a new twist to transcription
Peptidyl-prolyl isomerases (PPIs) catalyse the cis–trans isomerisation of peptide bonds N-terminal to proline residues in polypeptide chains. They have roles in the folding of newly synthesised proteins and in the function of the immune system. In addition, members of the parvulin-like family of PPIs have been implicated in cell cycle control. Their activi
