A manually curated database of small molecule metabolites found in or produced by Saccharomyces cerevisiae (also known as Baker's yeast and Brewer's yeast). This database covers metabolites described in textbooks, scientific journals, metabolic reconstructions and other electronic databases. YMDB contains metabolites arising from normal S. cerevisiae metabolism under defined laboratory conditions as well as metabolites generated by S. cerevisiae when used in baking and in the production of wines, beers and spirits. YMDB currently contains 2027 small molecules with 857 associated enzymes and 138 associated transporters. Each small molecule has 48 data fields describing the metabolite, its chemical properties and links to spectral and chemical databases. Each enzyme/transporter is linked to its associated metabolites and has 30 data fields describing both the gene and corresponding protein. Users may search through the YMDB using a variety of database-specific tools. The simple text query supports general text queries of the textual component of the database. By selecting either metabolites or proteins in the search for field it is possible to restrict the search and the returned results to only those data associated with metabolites or with proteins. Clicking on the Browse button generates a tabular synopsis of YMDB's content. This browser view allows users to casually scroll through the database or re-sort its contents. Clicking on a given MetaboCard button brings up the full data content for the corresponding metabolite. A complete explanation of all the YMDB fields and sources is available. Under the Search link users will find a number of search options listed in a pull-down menu. The Chem Query option allows users to draw (using MarvinSketch applet or a ChemSketch applet) or to type (SMILES string) a chemical compound and to search the YMDB for chemicals similar or identical to the query compound. The Advanced Search option supports a more sophisticated text search of the text portion of YMDB. The Sequence Search button allows users to conduct BLASTP (protein) sequence searches of all sequences contained in YMDB. Both single and multiple sequence (i.e. whole proteome) BLAST queries are supported. YMDB also supports a Data Extractor option that allows specific data fields or combinations of data fields to be searched and/or extracted. Spectral searches of YMDB's reference compound NMR and MS spectral data are also supported through its MS, MS/MS, GC/MS and NMR Spectra Search links.

We report an analytical tool to facilitate metabolite identification based on an MS/MS spectral match of an unknown to a library of predicted MS/MS spectra of possible human metabolites. To construct the spectral library, the known endogenous human metabolites in the Human Metabolome Database (HMDB) (8,021 metabolites) and their predicted metabolic products via one metabolic reaction in the Evidence-based Metabolome Library (EML) (375,809 predicted metabolites) were subjected to in silico fragmentation to produce the predicted MS/MS spectra. This spectral library is hosted at the public MCID Web site (www.MyCompoundID.org), and a spectral search program, MCID MS/MS, has been developed to allow a user to search one or a batch of experimental MS/MS spectra against the library spectra for possible match(s). Using MS/MS spectra generated from standard metabolites and a human urine sample, we demonstrate that this tool is very useful for putative metabolite identification. It allows a user to narrow down many possible structures initially found by using an accurate mass search of an unknown metabolite to only one or a few candidates, thereby saving time and effort in selecting or synthesizing metabolite standard(s) for eventual positive metabolite identification.

Ranks of reference metabolites obtained for CoLaus pseudospectra, with UMDB as the spectral reference database, and with: peak- (P) or multiplet-mode (M), χ2- (X) or Z-scoring (Z), and without (C) or with decorrelation (D). Neighborhood parameter is δ = 0.03 in peak-mode, 0.01 in multiplet-mode. Shrinkage parameter is λ = 0.5 for decorrelation, 1 without. Reference metabolites are obtained from testable associations collected from targeted mGWAS [8, 18, 19]. Squares (□) indicate ranks not in the top 10% of UMDB listed metabolites, that is ranks greater than 18. Individual metabomatching figures including the eight highest ranked metabolite candidates for each pseudospectrum can be found in S1 Fig. Due to the differences in the peak and multiplet descriptions, the association of the HPD SNP with α-hydroxyisobutyrate is testable only in peak mode (S1F Fig), the association with 3-hydroxyisovalerate only in multiplet mode (S1G Fig).

Bacterial infection of crops is a major concern for farmers. Depending on the crop, yield losses can be significant. Management of bacterial disease requires applying antibiotic and copper chemical sprays, breeding for disease resistance, and inducing systematic acquired resistance, a type of whole plant immunity. Research using the model plant Arabidopsis has provided insights into plant-microbe interactions. The knowledge gained from researching Arabidopsis can be applied to crops. However, incomplete databases have limited the capabilities of identifying new signaling metabolites that set the basal defense state of Arabidopsis so that these plants can reduce bacterial infections. Analytical and natural products chemistry techniques in combination with omics-based methods are necessary for characterizing a larger suite of bioactive metabolites.

In 2014, EFSA has commissioned the compilation of a database specific for the pesticide residues including active substances and their metabolites, which comprises different genotoxicity endpoints, i.e. point mutations, structural and numerical chromosome aberrations, and DNA damage.
Data collection on individual genotoxicity studies has been retrieved from regulatory toxicological reports (Draft or Renewal Assessment Reports, i.e. DARs or RARs, respectively) as provided by the Rapporteur Member State (RMS) during the pesticide peer review process at European Level. The final EFSA conclusion on the overall genotoxic potential of active substance or metabolites taking into account all available information is not included in the database.
The database contains identity and genotoxicity information on more than 290 active substances and some of their metabolites.
The database represents a practical tool to complement in-silico tools i.e. QSAR (Quantitative structure–activity relationship models), grouping and read across for prediction of the genotoxicity hazard of the pesticides residues, and it supposes to enlarge the chemical domains for their application.

This data is the raw offline data of untargeted metabolomics in this study, including four groups of samples: MPXV group, HIV-MPXV group, HIV group, and healthy group. MPXV infection may affect the metabolic levels of patients. Through non targeted metabolomics techniques, it is known that mpox caused metabolic disorders in the body, especially downregulation of steroid hormone synthesis pathways. This study used urine samples, mpox samples were collected from hospitalized patients, HIV samples were collected from outpatient clinics, and healthy samples were recruited from volunteers. All samples were collected within 2 months. Immediately freeze the collected samples in liquid nitrogen and store them in a -80 ° C freezer for later use. After all samples are collected, they will be inactivated in a biosafety level 3 laboratory and then packaged and stored for later use. By analyzing this raw data, identified metabolites and differential metabolites can be obtained.
The analysis of bronchoalveolar lavage fluid (BALF) using mass spectrometry-based metabolomics can provide insight into lung diseases, such as asthma. However, the important step of compound identification is hindered by the lack of a small molecule database that is specific for BALF. Here we describe prototypic, small molecule databases derived from human BALF samples (n=117). Human BALF was extracted into lipid and aqueous fractions and analyzed using liquid chromatography mass spectrometry. Following filtering to reduce contaminants and artifacts, the resulting BALF databases (BALF-DBs) contain 11,737 lipid and 658 aqueous compounds. Over 10% of these were found in 100% of samples. Testing the BALF-DBs using nested test sets produced a 99% match rate for lipids and 47% match rate for aqueous molecules. Searching an independent dataset resulted in 45% matching to the lipid BALF-DB compared to < 25% when general databases are searched. Overall, the BALF-DBs can reduce false positives and improve confidence in compound identification compared to when general databases are used.
Chimeric MS/MS spectra contain fragments from multiple precursor ions and therefore hinder compound identification in metabolomics. Historically, deconvolution of these chimeric spectra has been challenging and relied upon specific experimental methods that introduce variation in the ratios of precursor ions between multiple MS/MS scans. DecoID introduces a complementary, method-independent approach where database spectra are computationally mixed to match an experimentally acquired spectrum using LASSO regression. When applied to human plasma, DecoID increased the number of identified metabolites by over 30%.
