Hydrogen with deuterium, enzymatic

The mechanism of hydrogen transfer in enzymatic transamination has been studied by Konikova, Kritzmann and Teiss (102) ine xperiments with a deuterio-alanine. In the presence of crude gl-aph and of KG the greater part of the deuterium contained in labeled AL passes into the water the newly formed GL contains practically no excess of D. No significant loss of... [Pg.6]

The light hydrogen isotope protium (H) can be replaced by deuterium (D) in the hydrogenic sites of the water species (i.e. HOD, D2O, H+3O, H+2OD, I>20H, D+sO, etc), under certain circumstances, and as a consequence deuterium may replace protium into some sensitive positions of enzymes and substrates these replacements have been designated as solvent isotope effects (SIE) and usually they affect the kinetic and equilibrium constants associated with the enzymatic reactions. Obviously, these SIE are related to the isotopac solvents and thus... [Pg.256]
