Zileuton, a 5-Lypoxigenase Inhibitor, is Antiparasitic and Prevents Inflammation in the Chronic Stage of Heart Chagas Disease.

Chronic Chagas cardiomyopathy is associated with an unbalanced immune response and impaired heart function, and available drugs do not prevent its development. Zileuton (Zi), a 5-lypoxigenase inhibitor, affects inflammatory/pro-resolution mediators. Herein, Zi treatment in the early phase of infection reduced parasitemia associated mainly with the direct effect of Zi on the parasite, and the enzyme epoxide hydrolase was the potential molecular target behind the trypanocidal effect.

Biochemical characterization of an esterase from Thermobifida fusca YX with acetyl xylan esterase activity.

Biomarker evaluation for prognostic stratification of patients with COVID-19: the added value of quantitative chest CT.

Pulmonary disease burden and biomarkers are possible predictors of outcomes in patients with COVID-19 and provide complementary information. In this study, the prognostic value of adding quantitative chest computed tomography (CT) to a multiple biomarker approach was evaluated among 148 hospitalized patients with confirmed COVID-19. Patients admitted between March and July 2020 who were submitted to chest CT and biomarker measurement (troponin I, D-dimer and C-reactive protein) were retrospectively analyzed.

Convolutional Neural Networks to Estimate Dry Matter Yield in a Guineagrass Breeding Program Using UAV Remote Sensing.

Forage dry matter is the main source of nutrients in the diet of ruminant animals. Thus, this trait is evaluated in most forage breeding programs with the objective of increasing the yield. Novel solutions combining unmanned aerial vehicles (UAVs) and computer vision are crucial to increase the efficiency of forage breeding programs, to support high-throughput phenotyping (HTP), aiming to estimate parameters correlated to important traits.

Structural and functional characterization of the glutathione peroxidase-like thioredoxin peroxidase from the fungus Trichoderma reesei.

Glutathione peroxidases (GPx) are a family of enzymes with the ability to reduce organic and inorganic hydroperoxides to the corresponding alcohols using glutathione or thioredoxin as an electron donor. Here, we report the functional and structural characterization of a GPx identified in Trichoderma reesei (TrGPx). TrGPx was recombinantly expressed in a bacterial host and purified using affinity.

An epoxide hydrolase from endophytic Streptomyces shows unique structural features and wide biocatalytic activity.

The genus Streptomyces is characterized by the production of a wide variety of secondary metabolites with remarkable biological activities and broad antibiotic capabilities. The presence of an unprecedented number of genes encoding hydrolytic enzymes with industrial appeal such as epoxide hydrolases (EHs) reveals its resourceful microscopic machinery. The whole-genome sequence of Streptomyces sp.

Crystal structures of the closed form of Mycobacterium tuberculosis dihydrofolate reductase in complex with dihydrofolate and antifolates.

Tuberculosis is a disease caused by Mycobacterium tuberculosis and is the leading cause of death from a single infectious pathogen, with a high prevalence in developing countries in Africa and Asia. There still is a need for the development or repurposing of novel therapies to combat this disease owing to the long-term nature of current therapies and because of the number of reported resistant strains. Here, structures of dihydrofolate reductase from M.

The molecular structure of an epoxide hydrolase from Trichoderma reesei in complex with urea or amide-based inhibitors.

Epoxide hydrolases (EHs) are enzymes involved in the metabolism of endogenous and exogenous epoxides, and the development of EH inhibitors has important applications in the medicine. In humans, EH inhibitors are being tested in the treatment of cardiovascular diseases and show potent anti-inflammatory effects. EH inhibitors are also considerate promising molecules against infectious diseases.

Substrate and inhibitor selectivity, and biological activity of an epoxide hydrolase from Trichoderma reesei.

Epoxide hydrolases (EHs) are present in all living organisms and catalyze the hydrolysis of epoxides to the corresponding vicinal diols. EH are involved in the metabolism of endogenous and exogenous epoxides, and thus have application in pharmacology and biotechnology. In this work, we describe the substrates and inhibitors selectivity of an epoxide hydrolase recently cloned from the filamentous fungus Trichoderma reesei QM9414 (TrEH).

Structure of a soluble epoxide hydrolase identified in Trichoderma reesei.

Epoxide hydrolases (EHs) are enzymes that have high biotechnological interest for the fine and transformation industry. Several of these enzymes have enantioselectivity, which allows their application in the separation of enantiomeric mixtures of epoxide substrates. Although two different families of EHs have been described, those that have the α/β-hidrolase fold are the most explored for biotechnological purpose.

Data set of optimal parameters for colorimetric red assay of epoxide hydrolase activity.

The data presented in this article are related to the research article entitled "Epoxide hydrolase of Trichoderma reesei: Biochemical properties and conformational characterization" [1]. Epoxide hydrolases (EHs) are enzymes that catalyze the hydrolysis of epoxides to the corresponding vicinal diols. This article describes the optimal parameters for the colorimetric red assay to determine the enzymatic activity, with an emphasis on the characterization of the kinetic parameters, pH optimum and thermal stability of this enzyme.

Epoxide hydrolase of Trichoderma reesei: Biochemical properties and conformational characterization.

Epoxide hydrolases (EHs) are enzymes that are present in all living organisms and catalyze the hydrolysis of epoxides to the corresponding vicinal diols. EHs have biotechnological potential in chiral chemistry. We report the cloning, purification, enzymatic activity, and conformational analysis of the TrEH gene from Trichoderma reesei strain QM9414 using circular dichroism spectroscopy.
