Abstract
NADP and NADP analog were phosphorylated to NAD diphosphate and NADP analog phosphate, respectively, by an enzyme preparation of Proteus mirabilis (IFO 3849). The degradation products from NAD-diphosphate and NADP analog phosphate by the snake venom nucleotide pyrophosphatase were identical with nicotinamide riboside diphosphate and adenosine 2′(3′), 5′-diphosphate.
