Mosin O. V., Biography
Russian scientist, biochemist, researcher of water, engineer of technology (1992), candidate of Science (Ph. D in Chemistry) Dr. Oleg V. Mosin was bourn in a military family and had spent much time in Ural region. In 1992 he graduated from Moscow State Academy named after M.V. Lomonosov and taken post-graduate studies from the same Academy on the theme of biotechnological methods of production of stable isotope labeled compounds and further worked under the leadership of prominent Soviet and Russian scientist the founder of Soviet and Russian school of biotechnology Doctor of Sciences, academician, professor Vitaly I. Shvetz where he studied many living objects to resistance to highly deuterium content in growth media. By employing special adaptation technique many living cells were adapted to high deuterium content in growth media to prepare deuterated macromolecules. A special attention was given to the investigation of biological adaptation to 2H2O allowing cells to synthesize deuterated forms of macromolecules (DNA and short-chain individual proteins both with well known amino acid sequence and conformation) with a certain structure allowing their functioning in heavy water environment. For this purpose the special biotechnological approaches based on using the strains with improved properties when growing on heavy water for obtaining fully deuterated DNA and individual proteins were developed by him for allowing to prepare deuterated macromolecules in gram scale quantities.
His dissertation thesis was entitled of “The developing of various biotechnological methods for the preparation of proteins, amino acids and nucleosides labeled with stable isotopes - 2H and 13C with highly levels of isotopic enrichment”. In frames of his work many living cells of different origin were adapted to high deuterium content in growth media by employing a special adaptation technique. The scope of his scientific interests comprising water (heavy water), and its structure, the questions of keeping information by water, stable isotopes, application of various microbial objects for the preparation of cell compounds labelled with stable isotopes 2H, 13C, 15N, including proteins, amino acids and nucleosises; biosynthesis and metabolism of isotopically labeled compounds; biological adaptation to heavy water, effects of heavy water on living objects; ecology and molecular evolution.
His research deals with preparation of isotopically labelled cell compounds with using microbial strains e.g.; biological adaptation to heavy water; preparation of [2H]-and [13C]-amino acids with high levels of enrichment via bioconvertion of methanol/13C-methanol/deuteron-methanol and heavy water in methylotrophs Brevibacterium methylicum and Methylobacillus flagellatum; the studying of L-Phe biosynthesis by facultative methylotroph Brevibacterium methylicum in the presence of heavy water; biosynthesis of bacteriorhodopsin labeled with deuterium on the residues of aromatic amino acids [2,3,4,5,6-D5]phenylalanine, [3,5-D2]tyrosine and [2,4,5,6,7-D5]tryptophan; the growth of Bacillus subtilis and biosynthesis of inosine on highly deuterated media, containing heavy water and deuterated biomass of methylotrophic bacterium B. methylicum; electron impact mass-spectrometry and NMR in evaluation of levels of enrichment in labelled cell compounds, and cell adaptation to heavy water.
According to O.V. Mosin's research there have been published about 40 scientific works and monographies on adaptation and mechanisms of adaptation of cells to heavy water, two patents on preparation of deuterium labeled biological active compounds were made out.
In frames of his research the mechanism of physiological adaptation of microbic objects of various taxonomy characteristics to heavy water was investigated and the method of adaptation of cells to heavy water was developed; there have been carried out the biosynthesis of the 2H-, 13C, 15N-labelled biologically active compounds, including amino acids, proteins, lipids and carbohydrates of a high level of isotope enrichment was carried out due to bioconversion of 2H-, 13C, 15N-labeled growth substrates in genetically modified cells of С1-utilizing methylotrophic facultative and obligate bacteria Brevibacterium methylicum and Methylobacillus flagellatum; there was carried out the biosynthesis of deuterated amino acids L-Phe and L-Leu by facultative methylotrophic bacteria B. methylicum at the presence of high concentration of heavy water; there was executed the biosynthesis of deuterated bacteriorodopsine, carrying out a role of ATP-dependent translocase in cellular membrane of halophil bacteria Halobacterium halobium and further functioning of deuterated bacteriorodopsine was investigated; there was is carried out the biosynthesis of D-labelled purine ribonucleoside inosine by bacterium Bacillus subtilis in the presence of heavy water; as well as morphological and biosynthetic parameters of many cells adapted to heavy water of biological objects was investigated.
Dr. Oleg V. Mosin is a winner of the President Prize (1996) for distinguished successes in studies and scientific research and the Prize of Prof. Marinov (Bolgaria, 2010).
