Bioelectrocatalytic reduction of NAD+ to NADH proceeded smoothly on diaphorase modified electrodes and the results demonstrated the importance of the surface modification since the reaction occurred practically within the modified layer.Tomokazu Matsue and Hsien-Chang Chang and Isamu Uchida and Tetsuo ...
Phenformin reduced the NAD + /NADH ratio and decreased cellular aspartate level. Moreover treatment of HCC827-GR cells with 伪-ketobutyrate (AKB) which is an electron acceptor or aspartate significantly reversed inhibition of HCC827-GR cells proliferation. In conclusion, we propose that phenform...
Cofactor regeneration; i.e., regiospecific conversion of NAD(+) to 1,4-NADH, has been extensively studied and is a crucial component in the eventual use of 1,4-NADH in a variety of bioorganic synthesis processes involving the formation of chiral organic compounds. We have studied the ...

The reduction of aldehydes to primary alcohols, and of ketones to secondary alcohols is primarily through aldo-keto reductases or short-chain dehydrogenases/reductases, two of the superfamilies of NAD(P)H-dependent reductases. In some cases, reduction of aldehydes to alcohols is catalyzed by ...
1) and a specific activity of 0.070 ± 0.004 µmol of oxidized NADH min−1 mg−1 of MtATPS was measured. Under these conditions, the rate-limiting step was the pyrophosphatase activity. This highlights the need for rapid pyrophosphate degradation (Fig. 2a) to avoid a ...

In cells in which respiratory sulfate reduction is inhibited, NADH:NAD+ ratios should increase leading to derepression of the sulfate-reduction pathway. In support of this, in (per)chlorate or nitrate-stressed wild-type G20 we observed higher NADH:NAD+ ratios, increased transcripts and increased ...
For the equations below, which molecule is oxidized and which is reduced? a) H_2S + NAD^+ \to NADH + S + H^+ b) G_3P + NAD^+ + P_i \to 1,3-dPGA + NADH We defined the oxidation and the reduction reactions involving NADH that are...
