den Ridder, Maxime;Knibbe, Ewout;van den Brandeler, Wiebeke;Daran-Lapujade, Pascale;Pabst, Martin research published 《 A systematic evaluation of yeast sample preparation protocols for spectral identifications, proteome coverage and post-isolation modifications》, the research content is summarized as follows. The importance of obtaining comprehensive and accurate information from cellular proteomics experiments asks for a systematic investigation of sample preparation protocols. In particular when working with unicellular organisms with strong cell walls, such as found in the model organism and cell factory Saccharomyces cerevisiae. Here, we performed a systematic comparison of sample preparation protocols using a matrix of different conditions commonly applied in whole cell lysate, bottom-up proteomics experiments The different protocols were evaluated for their overall fraction of identified spectra, proteome and amino acid sequence coverage, GO-term distribution and number of peptide modifications, by employing a combination of database and unrestricted modification search approaches. Ultimately, the best protocols enabled the identification of approx. 65-70% of all acquired fragmentation spectra, where addnl. de novo sequencing suggests that unidentified spectra were largely of too low spectral quality to provide confident spectrum matches. Generally, a range of peptide modifications could be linked to solvents, additives as well as filter materials. Most importantly, the use of moderate incubation temperatures and times circumvented excessive formation of modification artifacts. The collected protocols and large sets of mass spectrometric raw data provide a resource to evaluate and design new protocols and guide the anal. of (native) peptide modifications. The single-celled eukaryote yeast is a widely used model organism for higher eukaryotes in which, for example, the regulation of glycolysis is studied in the context of health and disease. Moreover, yeast is a widely employed cell factory because it is one of the few eukaryotic organisms that can efficiently grow under both aerobic and anaerobic conditions. Large-scale proteomics studies have become increasingly important for single-celled model organisms, such as yeast, in order to provide fundamental understanding of their metabolic processes and proteome dynamics under changing environmental conditions. However, comprehensive and accurate cellular proteomics experiments require optimized sample preparation procedures, in particular when working with unicellular organisms with rigid cell walls, such as found in yeast. Protocols may substantially bias towards specific protein fractions, modify native protein modifications or introduce artificial modifications. That lowers the overall number of spectral identifications and challenges the study of native protein modifications. Therefore, we performed a systematic study of a large array of protocols on yeast grown under highly controlled conditions. The obtained outcomes, the collected protocols and the mass spectrometric raw data enable the selection of suitable sample preparation elements and furthermore support the evaluation of (native) peptide modifications in yeast, and beyond.

MAT2a is a methionine adenosyltransferase that synthesizes the essential metabolite S-adenosylmethionine (SAM) from methionine and ATP. Tumors bearing the co-deletion of p16 and MTAP genes have been shown to be sensitive to MAT2a inhibition, making it an attractive target for treatment of MTAP-deleted cancers. A fragment-based lead generation campaign identified weak but efficient hits binding in a known allosteric site.

Davis, Lissa A.;Running, Cordelia A. research published 《 Repeated exposure to epigallocatechin gallate solution or water alters bitterness intensity and salivary protein profile》, the research content is summarized as follows. Polyphenols, bitter and astringent compounds present in many healthy foods, induce varied sensory responses across individuals. These differences in liking and flavor intensity may be attributable, in part, to differences in saliva. In the current study, we tested the effect of repeated consumption of a bitter polyphenol (epigallocatechin gallate, EGCG) solution on perceived bitterness intensity and salivary protein composition We hypothesized exposure to EGCG would cause an increase in concentrations of salivary proteins that inhibit bitterness of polyphenols. We also hypothesized that participants with higher habitual polyphenol, specifically the flavanols, intake would experience less bitterness from EGCG solutions than those with low habitual intake, and that the high flavanol consumers would be more resistant to salivary alterations. We also tested whether bovine milk casein, a food analog for salivary proteins that may suppress bitterness, would decrease bitterness intensity of the EGCG solution and mitigate effects of the intervention. Participants (N = 37) in our crossover intervention adhered to two-week periods of daily bitter (EGCG) or control (water) solution consumption. Bitterness intensity ratings and citric acid-stimulated saliva were collected at baseline and after each exposure period. Results indicate that bitterness intensity of the EGCG solution decreased after polyphenol (bitter EGCG) exposure compared to control (water) exposure. Casein addition also decreased bitterness intensity of the EGCG solution While there was not a significant overall main effect of baseline flavanol intake on solution bitterness, there was an interaction between intervention week and baseline flavanol intake. Surprisingly, the higher flavanol intake group rated EGCG solutions as more bitter than the low and medium intake groups. Of proteins relevant to taste perception, several cystatins changed in saliva in response to the intervention. Interestingly, most of these protein alterations occurred more robustly after the control (water) exposure rather than the bitter (EGCG) exposure, suggesting that addnl. factors not quantified in this work may influence salivary proteins. Thus, we confirm in this study that exposure to bitterness suppresses ratings of bitterness over time, but more work needs to establish the causal factors of how diet influences salivary proteins.

da Silva-Lopez, Raquel Elisa;de Araujo, Thayane Aparecida Alves;Monteiro, Helvio Jose Jalles;Teixeira, Erika Maria Gomes Ferreira;Tupi, Lucas;da Silva Bon, Elba Pinto research published 《 Study of protease activity from Aspergillus awamori INCQS2B.361U2/1 extracellular fraction and modification of culture medium composition to isolate a novel aspartic protease》, the research content is summarized as follows. Aspergillus awamori was cultivated in a modified Breccia medium, and the extracellular fraction was obtained, which presented 260 ±15μg of protein/mg and specific protease activity of 3.87 ± 0.52 mM.min-1.mg of protein-1using Nα-p-tosyl-L-arginine Me ester hydrochloride (L-TAME) as substrate. This fraction showed major proteins about 104 and 44 kDa and maximal protease activity at pH 5.5, 6.5, and 9.0, suggesting that A. awamori secretes acidic, neutral, and alk. proteases with expressive thermal stability, however, aspartic protease was the most important activity. When yeast extract was supplemented to a modified Breccia medium, A. awamori protein secretion and protease activity were maximal and the affinity chromatog. on pepstatin-agarose was employed to isolate the aspartic protease activity, which was called ASPA, with approx. 75 kDa. ASPA maximal activity was obtained at pH 4.5 and 6.5, and 50 °C. Pepstatin inhibited about 80% of ASPA activity, with IC50 and Ki values of 0.154 and 0.072 μM, resp. ASPA cleaved protein and peptides substrates with the highest activity against gelatin (95 U/mg) and good peptidase activity with KM 0.0589 mM and Vmax 1.909 mM.min-1.mg protein-1, using L-TAME as substrate. A. awamori extracellular fraction is a source of proteases with important activity, and the supplementation of modified Breccia medium increased the aspartic protease production This enzyme presented different biochem. characteristics from the previously reported A. awamori aspartic proteases. Therefore, ASPA is an excellent candidate for biotechnol. application due to its important activity and thermostability.

da Rosa, Rafael;Grand, Lucie;Schenkel, Eloir P.;Sibelle Campos Bernardes, Lilian;Jacolot, Maiwenn;Popowycz, Florence research published 《 The Use of 5-Hydroxymethylfurfural towards Fine Chemicals: Synthesis and Direct Arylation of 5-HMF-Based Oxazoles》, the research content is summarized as follows. The synthesis of 5-HMF-based oxazole compounds I [Ar = 4-MeC6H4, 3-FC6H4, 3-thienyl, etc.] were reported. While 5-HMF could be easily converted into the oxazole derivative through the Van Leusen reaction, the direct arylation step needed to access the final compounds was problematic at first. After optimization, a palladium-catalyzed procedure had been developed and used for the synthesis of a series of 33 derivatives This article reported an extension of the late-stage CH arylation reaction as an application to the oxazole platform derived from biosourced 5-HMF. The challenges in the preparation of the derivatives containing some electron-withdrawing substituents were overcome by the use of a palladium-free method.

da Rosa, Rafael;Dambros, Bibiana Paula;Hoehr de Moraes, Milene;Grand, Lucie;Jacolot, Maiwenn;Popowycz, Florence;Steindel, Mario;Schenkel, Eloir Paulo;Campos Bernardes, Lilian Sibelle research published 《 Natural-product-inspired design and synthesis of two series of compounds active against Trypanosoma cruzi: Insights into structure-activity relationship, toxicity, and mechanism of action》, the research content is summarized as follows. Chem. scaffolds of natural products have historically been sources of inspiration for the development of novel mols. of biol. relevance, including hit and lead compounds To identify new compounds active against Trypanosoma cruzi, we designed and synthesized 46 synthetic derivatives based on the structure of two classes of natural products: THF lignans (Series 1) and oxazole alkaloids (Series 2). Compounds were screened in vitro using a cellular model of T. cruzi infection. In the first series of compounds, 11 derivatives of hit compound 5 (EC50 = 1.1 μM) were found to be active; the most potent (7, 8, and 13) had EC50 values of 5.1-34.2 μM. In the second series, 17 analogs were found active at 50 μM; the most potent compounds (47, 49, 59, and 63) showed EC50 values of 24.2-49.1 μM. Active compounds were assessed for selectivity, hemocompatibility, synergistic potential, effects on mitochondrial membrane potential, and inhibitory effect on trypanothione reductase. All active compounds showed low toxicity against uninfected THP-1 cells and human erythrocytes. The potency of compounds 5 and 8 increased steadily in combination with benznidazole, indicating a synergistic effect. Furthermore, compounds 8, 47, 49, 59, and 63 inhibited parasitic mitochondria in a dose-dependent manner. Although increased reactive oxygen species levels might lead to mitochondrial effects, the results indicate that the mechanism of action of the compounds is not dependent on trypanothione reductase inhibition. In silico calculation of chem. descriptors and principal component anal. showed that the active compounds share common chem. features with other trypanocidal mols. and are predicted to have a good ADMET profile. Overall, the results suggest that the compounds are important candidates to be further studied for their potential against T. cruzi.
