13. Enzymatic Activity in the Gastrointestinal Tract of Pimelodus maculatus (Teleostei, Siluriformes) in Two Neotropical Reservoirs with Different Trophic Conditions
Enzymatic activities for digestion of proteins and carbohydrates were compared among three organs of the digestive system of Pimelodus maculatus in two reservoirs with different trophic conditions during the winter of 2006. The aim was to test the hypothesis that enzymatic activity for the digestion of proteins and carbohydrates differed among organs and tha

14. Characterization and expression analysis of chymotrypsin after bacterial challenge in the mud crab, Scylla paramamosain
Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal

15. Extracellular proteases of Halobacillus blutaparonensis strain M9, a new moderately halophilic bacterium
Halophilic microorganisms are source of potential hydrolytic enzymes to be used in industrial and/or biotechnological processes. In the present study, we have investigated the ability of the moderately halophilic bacterium Halobacillus blutaparonensis (strain M9), a novel species described by our group, to release proteolytic enzymes. This bacterial strain a

16. Hemolytic activity of venom from crown-of-thorns starfish Acanthaster planci spines
Background : The crown-of-thorns starfish Acanthaster planci is a venomous species from Taiwan whose venom provokes strong hemolytic activity. To understand the hemolytic properties of A. planci venom, samples were collected from A. planci spines in the Penghu Islands, dialyzed with distilled water, and lyophilized into A. planci spine venom (ASV) powder. R

17. Kazal-type serine proteinase inhibitors in the midgut of Phlebotomus papatasi
Sandflies (Diptera: Psychodidae) are important disease vectors of parasites of the genus Leishmania, as well as bacteria and viruses. Following studies of the midgut transcriptome of Phlebotomus papatasi, the principal vector of Leishmania major, two non-classical Kazal-type serine proteinase inhibitors were identified (PpKzl1 and PpKzl2). Analyses of expres

18. Colicin type 7 produced by majority of Shigella sonnei isolated from Thai patients with diarrhoea
Thirty one out of 153 strains of Shigella sonnei isolated from Thai patients with diarrhoea showed antibacterial activity against S. sonnei by agar well diffusion method. All of them harbor plasmids with the genetic determination of colicin type 7 (Js) gene but without colicin E and colicin U gene. The PCR product obtained from strain 35/44 was shown to be t

19. Influence of season, environment and feeding habits on the enzymatic activity of peptidase and β-glucosidase in the gastrointestinal tract of two Siluriformes fishes (Teleostei)
The enzymatic activities involved in the digestion of proteins and carbohydrates were compared among three organs of the digestive track of two Siluriformes fish species, and between two areas: a reservoir, and an area downriver of it. Our aim was to test the hypothesis that the digestive organs of species with varied feeding habits have different enzymatic

20. CORRELAÇÃO DA ATIVIDADE DO PROTEASSOMA, EXPRESSÃO DE CD44 E ENZIMAS PROTEOLÍTICAS EM EXTRATOS INTESTINAIS DE CAMUNDONGOS TRATADOS COM 1,2 DIMETILHIDRAZINA E INIBIDORES BOWMAN-BIRK
The Bowman-Birk inhibitors (BBI) are protein molecules containing two distinct inhibitory domains for trypsin and chymotrypsin-like enzymes. The interest for this class of inhibitors is based on studies which demonstrated a protective effect promoted by BBI, particularly for chemically-induced cancers. In the present work, we evaluated the effects of BBI iso

21. ProspecÃÃo de molÃculas com potencial nutracÃutico em sementes de enterolobium contortisiliquum (VELL.) morong.: purificaÃÃo e caracterizaÃÃo parcial de trÃs inibidores de quimotripsina / Prospection for molecules with nutraceutical properties in enterolobium contortisiliquum (VELL.) morong. seeds: purification and partial characterization of three chymotrypsin inhibitors
Sementes de leguminosas constituem uma das principais fontes de proteÃna na alimentaÃÃo humana e animal. Outros interesses tÃm sido despertados para o potencial nutracÃutico inerente a essas proteÃnas vegetais, uma vez que muitas proteÃnas bioativas, atà entÃo referidas apenas como fatores antinutricionais, tÃm exercido efeitos benÃficos no organi

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

23. Resolução da estrutura tridimensional do inibidor tríptico e quimotrípico de Vigna unguiculata em complexos binário e ternário
The inhibitor BTCI (Black-eyed Pea Trypsin and Chymotrypsin Inhibitor) was purified from Vigna unguiculata seeds and crystallized in binary complex with -trypsin and in ternary complex with - chymotrypsin and -trypsin at pH 4.5 and 7.5. The crystallographic data were collected at the National Synchrotron Light Laboratory (LNLS). The c

24. Análise bioquímica inicial do proteassoma em populações do Trypanosoma cruzi com diferentes fenótipos de resistência ao benzonidazol
Differences in susceptibility to benznidazole (Bz) and nifurtimox (NFX) among populations of Trypanosoma cruzi may explain, at least in part, the differences in efficacy of treatment of Chagas disease. The proteasome has an important role in the degradation of normal proteins, damaged, mutated, or denatured, including the degradation of regulatory proteins o
