Abstract

Catalysis of NAD+-dependent ADP-ribosylation of proteins, nucleic acids, or small molecules has evolved in at least three structurally unrelated superfamilies of enzymes, namely ADP-ribosyltransferase (ART), the Sirtuins, and probably TM1506. Of these, the ART superfamily is the most diverse in terms of structure, active site residues, and targets that they modify. The primary diversification of the ART superfamily occurred in the context of diverse bacterial conflict systems, wherein ARTs play both offensive and defensive roles. These include toxin–antitoxin systems, virus-host interactions, intraspecific antagonism (polymorphic toxins), symbiont/parasite effectors/toxins, resistance to antibiotics, and repair of RNAs cleaved in conflicts. ARTs evolving in these systems have been repeatedly acquired by lateral transfer throughout eukaryotic evolution, starting from the PARP family, which was acquired prior to the last eukaryotic common ancestor. They were incorporated into eukaryotic regulatory/epigenetic control systems (e.g., PARP family and NEURL4), and also used as defensive (e.g., pierisin and CARP-1 families) or immunity-related proteins (e.g., Gig2-like ARTs). The ADP-ribosylation system also includes other domains, such as the Macro, ADP-ribosyl glycohydrolase, NADAR, and ADP-ribosyl cyclase, which appear to have initially diversified in bacterial conflict-related systems. Unlike ARTs, sirtuins appear to have a much smaller presence in conflict-related systems.
