description | NAD<sup>+</sup> has emerged as a crucial element in both bioenergetic and signaling pathways, since it acts as a key regulator of cellular and organism homeostasis. NAD<sup>+</sup> is a coenzyme in redox reactions, a donor of adenosine diphosphate-ribose (ADPr) moieties in ADP-ribosylation reactions, and a substrate for sirtuins, a group of histone deacetylase enzymes that use NAD<sup>+</sup> to remove acetyl groups from proteins. NAD<sup>+</sup> is also a precursor of cyclic ADP-ribose, a second messenger in the release and signaling of Ca<sup>++</sup>, and of diadenosine tetraphosphate (Ap4A) and oligoadenylates (oligo2′-5′A)—two immune response-activating compounds. In the biological systems considered in this review, NAD<sup>+</sup> is mostly consumed in ADP-ribose (ADPr) transfer reactions. In this review, the roles of these chemical products are discussed in biological systems, such as in animals, plants, fungi and bacteria. In the review, ADP-ribosylating enzymes are introduced, as well as the importance to restore the NAD<sup>+</sup> pools in these systems. Finally, a special attention is presently focused on viral macrodomains, aimed to develop inhibitors to improve the immune response to viruses. |
