1. Activity of beta-glucosidase and levels of isoflavone glucosides in soybean cultivars affected by the environment.
The enzyme B-glucosidade hydrolyses the isoflavone glucosides developing aglycones, which are compounds with anticancer effects, that are also related with the astringency observed in soybean flavor. Due to the importance of this enzyme, a study was carried out to determine B-glucosidade activity in soybean (Glycine max (L.) Merrill) cultivars with different

2. Activity of beta-glucosidase and levels of isoflavone glucosides in soybean cultivars affected by the environment.
A enzima b-glicosidase hidrolisa os isoflavonóides glicosídeos desenvolvendo gliconas, compostos com ação anticancerígena, que também são relacionados com a adstringência observada no sabor da soja. Pela importância dessa enzima, conduziu-se um estudo para determinar a atividade da b-glicosidase em cultivares de soja (Glycine max (L.) Merrill) com t

3. Beta-glucosidase activity of soybean epicotyls in germination.
Isoflavones are compounds with benefits for human health and they are the mainly forms of glycosides in vegetables. ?-glucosidase (?-D-glucoside glucohydrolase, E.C.3.2.1.21) hydrolyses ?-D-glucosides releasing glucose and forming aglycone isoflavones. The aglycone isoflavone is the most bioavailable form of the glycosides. ?-glucosidase that converts glycos

4. Estudo das bases moleculares da especificidade pelo substrato de uma beta-glicosidase (AF052729) de Spodoptera frugiperda / Study of the molecular basis of substrate specificity in a Spodoptera frugiperda beta-glycosidase (AF052729)
The Mr 50,000 Spodoptera frugiperda beta-glycosidase (Sfgli50) has active site amino acid residues that interact non-covalently with the substrate. These non-covalent interactions determine the enzymes specificity towards its substrates. This work aims to study the role of these amino acids and its interactions with the substrate in the specificity of Sfgl

5. Expressão da trealase intestinal de Spodoptera frugiperda e efeito de beta-glicosídeos naturais em trealases de insetos / Molecular cloning, sequencing and expression of cDNA encoding intestinal trehalase of Spodoptera frugiperda
A trealase solúvel foi purificada a partir do intestino de S. frugiperda. Os pKas dos grupos catalíticos determinados por inativação química são similares aos pKas determinados por analise cinética, indicando que a enzima tem um grupo carboxila que atua como um nucleófilo e um grupo guanidina que atua como doador de prótons. Dietil pirocarbonato nã

6. Constituintes químicos voláteis e não-voláteis de Cochlospermum vitifolium (Willdenow) Sprengel
The essential oils from leaves, root bark and root wood of Cochlospermum vitifolium were investigated for the first time. The oils were obtained by hydrodistillation and analyzed by GC/MS. The main volatile constituents were beta-caryophyllene (8.2 - 46.5%), beta-bisabolene (11.5 - 29.3%), gamma-muurolene (28.4%), alpha-humulene (26.0%), 1-hydroxy-3-hexadeca

7. Caracterização de extratos de soja obtidos de grãos, farinha integral e isolado proteico visando a formulação e avaliação biologica (em coelhos) de bebida funcional a base de extrato de soja e polpa de pessegos / Characterization of soymilk obtained from soybean, whole soy flour and isolated soy protein, for the formulation and biological evaluation (in rabbits) of a functiolÍal beverage composed of soymilk and peaches pulp
Beverages based on soymilk and fruit juice have been an excellent option for the utilization and introduction of soy in the human diet. To the consumers, besides nutritional and functional benefits attributed to the soy, the beverages must attend the expected sensorial characteristics, keeping the original constituents of the raw materiais. Soy extracts (soy

8. Steroidal and triterpenoidal glucosides from Passiflora alata
Cinco glicosídeos foram isolados a partir das folhas de P. alata. Após extensivas análises espectroscópicas, as estruturas 1-5 foram identificadas como sendo o 3-O-beta-D-glicopiranosil-estigmasterol (1), o ácido 3-O-beta-D-glicopiranosil-oleanólico (2), o ácido 3-O-beta-D-glicopiranosil-(1->3)-beta-D-glicopiranosil-oleanólico (3), o ácido 3-O-beta-

9. Atividade de beta-glicosidase e níveis de isoflavonóides glicosídios em cultivares de soja, influenciadas pelo ambiente
The enzyme beta-glucosidase hydrolyses the isoflavone glucosides developing aglycones, which are compounds with anticancer effects, that are also related with the astringency observed in soybean flavor.

10. The protein encoded by the rolB plant oncogene hydrolyses indole glucosides.
The rolB gene of Agrobacterium rhizogenes, whose expression stimulates the formation of roots by transformed plant tissues and other growth alterations in transgenic plants, codes for a beta-glucosidase able to hydrolyse indole-beta-glucosides. Indeed, we show that extracts of bacteria and/or plant tissue expressing the rolB protein hydrolyse indoxyl-beta-gl

11. Beta-glucoside permease represses the bgl operon of Escherichia coli by phosphorylation of the antiterminator protein and also interacts with glucose-specific enzyme III, the key element in catabolite control.
The beta-glucoside (bgl) operon of Escherichia coli is subject to both positive control by transcriptional termination/antitermination and negative control by the beta-glucoside-specific transport protein, an integral membrane protein known as enzyme IIBgl. Previous results led us to speculate that enzyme IIBgl exerts its negative control by phosphorylating

12. Analysis of the Erwinia chrysanthemi arb genes, which mediate metabolism of aromatic beta-glucosides.
Erwinia chrysanthemi is one of the few members of the family Enterobacteriaceae that is capable of metabolizing most of the naturally occurring beta-glucosides. We previously isolated the clb genes, which allow the use of the disaccharide cellobiose as well as the aromatic beta-glucosides arbutin and salicin. We report here the isolation of the arb genes, wh
