Calorimetric assays showed two different binding events: (i) inhibitor-protein interactions and (ii) toxin oligomerization processes. These hypotheses were also corroborated with dynamic light and small angle X-ray scattering assays. The crystal structure of the MjTX-I/suramin showed a totally different interaction mode compared to other PLA2-like/suramin complexes. Thus, we suggested a novel myotoxic mechanism for MjTX-I that may be inhibited by suramin. These results can further contribute to the search for inhibitors that will efficiently counteract local myonecrosis in order to be used as an adjuvant of conventional serum therapy.

Small-angle X-ray scattering studies of effect of pH and temperature on the global compactness on cellobiohydrolase I from Trichoderma harzianum

Una nueva serie documental retrata el auge y caída de una por las figuras más ignominiosas y a la vez representativas de la España reciente

Fatima, he says, is a hoax kept alive because of the attention it gets and the money it makes.* Lucy and her cousins were certainly delusional and the Catholic Church certainly exploited their delusions. Were the children of Fatima pious frauds or innocent victims of indoctrination? I lean toward the latter.

SAXS analysis is one of the techniques which has been provided answers regarding these parameters. The complexity of lignin requires sophisticated mechanism to assess its molecular stability and SAXS technique was effective for this purpose. Based on the obtained data, SAXS analysis contributed to the structural characterization of lignin obtained at two pH regarding to the size, shape and polydispersity

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 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.

Extensive studies have been made considering the potential for replacing and creating new environmentally friendly products from lignin. Currently, mainly industries of paper and biofuels are seeking solutions to utilize lignin to create higher value-added products, such as chemicals and high-performance composites. In this context, studies intend to know the lignin characteristics that even today is not well known, since its structural composition to its molecular stability.

Along with a comprehensive functional and biophysical characterization, the low-resolution structure of this enzyme was also determined by small-angle X-ray scattering. In addition, we described the production of phenolic compounds with antioxidant capacity from wheat arabinoxylan and sugarcane bagasse using AcFAE. The ability to specifically cleave ester linkages in hemicellulose is useful in several biotechnological applications, including improved accessibility to lignocellulosic enzymes for biofuel production.

Also, the Kappa coefficient is used as an objective function to be maximized through the PSO algorithm. As a result, the optimum setup parameters improved the success rate while the damage identification is being carried out. Indeed this proposed method is certainly very promising and constitutes a novelty. The proposed method achieves more than 75% hit rate that is significantly higher than the state-of-the-art approaches as presented in this paper. Furthermore, this approach yields a 20% improvement when considering the worst case scenario. Hence, this approach shows a practical application of expert and intelligent systems applied to more info damage identification in SHM systems. To conclude, the proposed approach successfully identifies structural damage with accuracy and efficiency.

The ED is used as input to the Simplified Fuzzy ARTMAP Network (SFAN) which is responsible for identifying get more info various different structural conditions. It is shown that the robustness provided by SFAN allows the evaluation of the progress of structural damage even under critical conditions. The structural damage was simulated by loosening bolts in a structure. Furthermore, the repaired condition was also considered by retightening bolts. The paper discusses the advantages and drawbacks of the approach in light of the experimental results.

Glycoside hydrolases (GHs) are enzymes found daniel valente dantas in all living kingdoms that are involved in multiple physiological functions. Due to their multiple enzymatic activities, GHs are broadly applied in bioethanol, food, and paper industry. In order to increase the productivity of these industrial processes, a constant search for novel and efficient enzymes has been proved to be necessary. In this context, metagenomics is here a powerful approach to achieve this demand. In the current study, we describe the discovery and characterization of a novel member of GH16 family derived from the sugarcane soil metagenome.
