Chikungunya virus (CHIKV), an Old World alphavirus, is transmitted to humans by infected mosquitoes and causes acute rash and arthritis, occasionally complicated by neurologic disease and chronic arthritis. One determinant of alphavirus virulence is nonstructural protein 3 (nsP3) that contains a highly conserved MacroD-type macrodomain at the N terminus, but the roles of nsP3 and the macrodomain in virulence have not been defined. Macrodomain is a conserved protein fold found in several plus-strand RNA viruses that binds to the small molecule ADP-ribose. Prototype MacroD-type macrodomains also hydrolyze derivative linkages on the distal ribose ring. Here, we demonstrated that the CHIKV nsP3 macrodomain is able to hydrolyze ADP-ribose groups from mono(ADP-ribosyl)ated proteins. Using mass spectrometry, we unambiguously defined its substrate specificity as mono(ADP-ribosyl)ated aspartate and glutamate but not lysine residues. Mutant viruses lacking hydrolase activity were unable to replicate in mammalian BHK-21 cells or mosquito <i>Aedes albopictus</i> cells and rapidly reverted catalytically inactivating mutations. Mutants with reduced enzymatic activity had slower replication in mammalian neuronal cells and reduced virulence in 2-day-old mice. Therefore, nsP3 mono(ADP-ribosyl)hydrolase activity is critical for CHIKV replication in both vertebrate hosts and insect vectors, and for virulence in mice. << Less

Sirtuins are an ancient family of NAD(+)-dependent deacylases connected with the regulation of fundamental cellular processes including metabolic homeostasis and genome integrity. We show the existence of a hitherto unrecognized class of sirtuins, found predominantly in microbial pathogens. In contrast to earlier described classes, these sirtuins exhibit robust protein ADP-ribosylation activity. In our model organisms, Staphylococcus aureus and Streptococcus pyogenes, the activity is dependent on prior lipoylation of the target protein and can be reversed by a sirtuin-associated macrodomain protein. Together, our data describe a sirtuin-dependent reversible protein ADP-ribosylation system and establish a crosstalk between lipoylation and mono-ADP-ribosylation. We propose that these posttranslational modifications modulate microbial virulence by regulating the response to host-derived reactive oxygen species. << Less
