Endoglucanases are key enzymes in the degradation of cellulose, the most abundant polymer on Earth. The aim of this work was to perform the biochemical and biophysical characterization of CelE2, a soil metagenome derived endoglucanase. CelE2 harbors a conserved domain from glycoside hydrolase family 5 (GH5) and a C-terminal domain with identity to Calx-beta domains. The recombinant CelE2 displayed preference for hydrolysis of oat beta-glucan, followed by lichenan and carboxymethyl cellulose. Optimum values of enzymatic activity were observed at 45 °C and pH 5.3, and CelE2 exhibited considerable thermal stability at 40 °C for up to 360 minutes. Regarding the cleavage pattern on polysaccharides, the release of oligosaccharides with a wide degree of polymerization indicated a characteristic of endoglucanase activity.

Small-angle X-ray scattering measurements at high micromolar concentration demonstrate a suramin-induced dimerization of the enzyme. These data indicating a dissimilar binding mode in the monomeric and oligomeric states, with a monomeric, 1:1 complex to be more likely to exist at the thrombin physiological, nanomolar concentration range. Collectively, close understanding on the structural basis for interaction is given which might establish a basis for design of suramin analogues targeting thrombin.

Endoglucanases are key enzymes applied to the conversion of biomass aiming for second generation biofuel production. In the present study we obtained the small angle X-ray scattering (SAXS) structure of the G. trabeum endo-1,4-β-glucanase Cel12A and investigated the influence of an important parameter, temperature, on both secondary and daniel valente dantas tertiary structure of the enzyme and its activity. The CD analysis for GtCel12A revealed that changes in the CD spectra starts at 55 oC and the Tm calculated from the experimental CD sigmoid curve using the Boltzmann function was 60.
Simplified fuzzy ARTMAP network-based method for assessment of structural damage applied to composite structures
Several snake species possess endogenous phospholipase A2 inhibitors (sbPLIs) in their blood plasma, the primary role of which is protection against an eventual presence of toxic phospholipase A2 (PLA2) from their venom glands in the circulation. These inhibitors have an oligomeric structure of three to six subunits Mario de Oliveira and have been categorized into three classes (α, β and γ) based on their structural features. SbγPLIs have been further subdivided into two subclasses according to their hetero or homomeric nature, respectively. Despite the considerable number of sbγPLIs described, their structures and mechanisms of action are check here still not fully understood. In the present study, we focused on the native structure of CNF, a homomeric sbγPLI from Crotalus durissus terrificus, the South American rattlesnake. Based on the results of different biochemical and biophysical experiments, we concluded that, while the native inhibitor occurs as a mixture of oligomers, tetrameric arrangement appears to be the predominant quaternary structure.
Padre Mário do Oliveira acusa clero de Ourfoim e a Igreja Católica do deter abusado psicologicamente das 3 crianças, a ponto de duas delas terem morrido do pneumonia por estarem fracas devido aos jejuns religiosos, e de terem enfiado a sobrevivente num convento e diz que este qual foi feito utilizando estas crianças foi pior de que crime do pedofilia que tanto se evidencia hoje nas igrejas. A Igreja só manté especialmentem a montagem fabricada pelo clero porque aquilo é 1 grande Empreendimento e rende bastante dinheiro. ...more

Structural features of lignin obtained at different alkaline oxidation conditions from sugarcane bagasse
The main reaction products from xylan polymers and phosphoric acid-pretreated sugarcane bagasse (PASB) were xylooligosaccharides, but, after a longer incubation time, xylobiose and xylose were also formed. Moreover, the use of SCXyl as pre-treatment step of PASB, prior to the addition of commercial cellulolytic cocktail, significantly enhanced the saccharification process. All these characteristics demonstrate the advantageous application of this enzyme in several biotechnological processes in food and feed industry and also in the enzymatic pretreatment of biomass for feedstock and ethanol production.
