As previously reported [Favilla, R. & Cavatorta, P. (1975) FEBS Lett. 50, 324-329], the enzyme horse liver alcohol dehydrogenase catalyzes a reaction between NAD+ and H2O2. The final isolated product was then called NADX because of its unknown structure. In this paper the results of spectroscopic investigations on this compound are described. They indicate that only the nicotinamide moiety of the original NAD+ molecule was modified by the action of hydrogen peroxide. From the 1H and 13C nuclear magnetic resonance spectra of NADX the following structure was deduced: adenosine(5')diphospho(5)-beta-D-ribose-NH-CH = C(CHO)-CONH2. This structure is consistent with both ultraviolet and reactivity measurements performed on NADX. A tentative mechanism for the whole peroxidatic reaction pathway leading to NADX is finally proposed.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
