LITERATURE
analysis
NMNAT can be applied to the colorimetric NMN or NaMN assays, which employ either adenylation of NMN to NAD by NMNAT or adenylation of NaMN to deamido-NAD (NaAD) by NMNAT followed by amidation of NaAD to NAD by NAD synthetase (NADS, EC 6.3.1.5) or an NAD cycling reaction using 12alpha-hydroxysteroid dehydrogenase (12a-HSD, EC 1.1.1.176) and diaphorase (DI, EC 1.6.99.3) to accumulate reduced 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium. The enzymatic cycling method enables detection of 0.5 mM (12.2 nM in the reaction mixture) NMN or NaMN in an automatic clinical analyzer

synthesis
-
overexpression of enzyme gene under anaerobic conditions in a strain lacking IdhA and pflB gene products leads to 3.21fold increase in NAD+ and 1.67fold increase in NADH in the recombinant strain. Enzyme expression restores cell growth and glucose utilization under anaerobic conditions. After 72 h, the recombinant strain can consume 14 g/l of lgucose and produce 6.23 g/l of succinic acid
