human ... NQO2(4835)
Application
Quinone oxidoreductase 2 has been used in a study to investigate whether recent advances in limiting paraquat′s toxicity makes it safer for use as an herbicide. Quinone oxidoreductase 2 has also been used in a study to investigate the NQO2-mediated toxicity of the chemotherapeutic drug CB1954.
The product from Sigma has been used to identify novel inhibitors of the enzyme NQO2. It has also been used to investigate the effect of afobazole on quinone reductase 2 activity.
Biochem/physiol Actions
Modulation of NQO2 activity can have effects on the levels and functions of the tumour suppressor, p53. Deletion of NQO2 can alter intra-cellular signalling via the NF-κB pathway.
Unique human oxidoreductase that uses Dihydronicotinamide riboside (NRH) as a cosubstrate, not NAD(P)H. Activates anticancer prodrugs. Putative melatonin receptor.
Unit Definition
One unit will catalyze the oxidation of one micromole of 1-methyl-1,4-dihydronicotinamide to 1-methylnicotinamide per minute in the presence of menadione at pH 7.4 at 37 °C.

As catabolites of nicotinamide possess physiological relevance, pyridones are often included in metabolomics measurements and associated with pathological outcomes in acute kidney injury (AKI). Pyridones are oxidation products of nicotinamide, its methylated form, and its ribosylated form. While they are

Carbonyl reductase activity catalyzes the two electron reduction of several endogenous and exogenous carbonyl substrates. Recent data indicate that the expression of human carbonyl reductase 3 (CBR3) is regulated by the master redox switch Nrf2. Nrf2 binds to conserved antioxidant
