Keywords: Database; Fragmentation; Mass Spectrometry; Metabolism, Metabolites.
Novel aspect: Global database consortium for metabolomics.
Global MS Data Base Consortium for Metabolomics (GMSDaBaCom) compose MS database of molecular ions such as protonated molecules, deprotonated molecules, radical cation and anion of molecules and their MSn fragment ions for analysis of metabolites in biological samples of biological fluids such as urine, blood, bile etc., cell and tissues. Metabolomics is important for scientific diagnosis, chemotherapy and new drug discovery. I use automatic data dependent exclusion MSn measurement for structure determination of biological component and their metabolites related with transporter, CYPs, nuclear receptors, blood stem cell and cancer. MS database links with the metabolic map. After measurement of mass spectrum of the biological samples, the search of MS data is able to identify the component of the metabolic map. The goal of GMSDaBaCom is establishment of automatic identification system of metabolites on metabolic map by biological mass spectrometry. GMSDaBaCom is organized with global MS users, global MS association and global MS makers. Global MS users access the home page of GMSDaBaCom to register and use MS database of the protonated molecules and their fragment ions. Global MS associations (IMSS, ASMS, ESMS, MSSJ etc.) and Global MS makers support GMSDaBaCom to gather and edit the molecular ions and their fragment ions MS data from global MS users. The official organisms (NIH, FDA. Kosei-sho etc.) support the fund of GMSDaBaCom to compose MS database of molecular ions and their fragment ions. Mass spectra of molecular and fragment ions depends on mass spectrometers, but they are compatible using such a soft as mass links by that Prof.R.Taguchi and A.Prof.M.Arita prepared lipid database (http://www. lipidbase.jp/) containing 2,705 lipids. Please access (http://www.lipid search.jp/). Prof.T.Nishioka contributed to prepare a metabolic map “KEGG”(http//www.genome.ad.jp/keg) that is reproduced a new metabolic map linked mass database by R.Arita. KEGG contains 13,222 components as the first metabolites, but the second metabolites are estimated more than 200,000. Prof.M.Tomita studied comprehensive analysis of metabolites in E. coli by CE MS and identified 500 metabolites using standard samples. I study metabolites in biological samples of human and animals as described above. I am a chair man of the 54th annual conference on mass spectrometry in Osaka,Japan after that I will engage to prepare the global mass database accessed freely by global MS users.
