  Enzymic Synthesis of NAD+ with the Specific Incorporation of Atomic Labels

  摘要：

  An enzymatic synthesis is described for the production of NAD(+) labeled with a radioactive or stable isotope at any desired position in the AMP or NMN(+) portions of the molecule. In the first step, ten enzyme-catalyzed reactions are coupled for the synthesis of nicotinic acid adenine dinucleotide (NaAD(+)) from glucose, nicotinic acid, and ATP. NAD(+) is formed from NaAD(+) and glutamine in the second step. Oxidized nicotinamide adenine dinucleotide was synthesized with H-3, C-14, or N-15 label specifically incorporated in the ribose or nicotinamide of the NMN(+) portion of NAD(+) as [H(N)1'H-3]NAD(+), [H(N)2'-H-3]NAD(+), [H(N)4'-H-3]NAD(+), [H(N)5'-H-3]NAD(+), [C(N)1'-C-14]NAD(+), [C(N)5'-C-14]NAD(+), [N(N)1-N-15, C(N)1'-C-14]NAD(+), and [N(N)1-N-15, C(N)5'-C-14]NAD(+). Nuclear magnetic resonance spectroscopy of [H(N)2'-H-2]NAD(+) as well as enzymatic degradation were used to verify the position of labels. Appropriately labeled glucose, ribose 5-phosphate, or nicotinic acid were the starting materials and were converted to NAD(+) using enzymes from the pentose pathway and the pathway for NAD(+) de novo synthesis. Yields of purified NAD(+) to 96% were obtained from starting glucose. The labeled NAD(+) is catalytically competent and is chromatographically and spectrophotometrically indistinguishable from authentic NAD(+). By using specifically labeled ATP as a precursor (Parkin, D. W.; Schramm, V. L. Biochemistry 1987, 26, 913-920), the method is readily adaptable for the synthesis of NAD(+) with single or multiple atomic labels at various positions in the AMP portion of the molecule. NAD(+) was synthesized from [8-C-14]ATP to give [C(A)8-C-14]NAD(+) as an example. Together these methods provide a general scheme for the efficient synthesis of NAD(+) of high purity with H-3, C-14, Or Other labels at any nonexchangeable position of the NMN(+) or AMP portions of the NAD(+) molecule.

With the natural substrates, NMN and pyrophosphate (PPi), the intrinsic KIEs of [1'-(14)C], [1-(15)N], [1'-(3)H], and [2'-(3)H] are 1.047, 1.029, 1.154, and 1.093, respectively. A unique quantum computational approach was used for TS analysis that included structural elements of the catalytic

  Described is a method for analysing the metabolites of a biological sample which comprises quantitatively determining one or more metabolites in said sample in a way that said quantitative determination resolves isotopic mass differences within one metabolite, said method being characterized in that the sample comprises or is derived from a cell which has been maintained under conditions allowing the uptake of an isotopically labeled metabolizable compound so that the metabolites in said cell are saturated with the isotope with which said metabolizable compound is labeled. This method may further comprise, prior to quantitative determining the metabolites, combining the biological sample (i.e. the first biological sample) with a second biological sample in which the metabolites are not isotopically labeled or are isotopically labeled differently from the first biological sample; and determining in said biological samples the relative quantity of metabolites which differ by their isotopical label. Furthermore described is a set of isotopically labeled metabolites obtainable by applying this method, as well as kits facilitating the application of this method and corresponding uses.
