説明
NADP was enzymatically synthesized from NAD and p-nitrophenyl phosphate or nucleoside monophosphate with the enzyme preparation of Proteus mirabilis (IFO 3849). In this phosphotransferring reaction, ATP did not serve as phosphoryl donor.In addition to NADP, an unidentified substance (Compound I) showing fluorescence with methyl ethyl ketone and having no coenzyme activity to glutamic dehydrogenase was synthesized. The yield of NADP was usually below 30 per cent of Compound I.NADP was isolated from the reaction mixture and its coenzyme activity to some dehydrogenases was demonstrated.A new derivative of NAD (Compound I) synthesized from NAD and p-nitrophenyl phosphate by the enzyme preparation of Proteus mirabilis (IFO 3849), was isolated from the reaction mixture.After degradation of this compound with snake venom nucleotide pyrophosphatase, Compound III was obtained. 5′-NMN was phosphorylated to Compound IV by the same enzyme preparation of P. mirabilis. By the determination of chemical constituents and ...
