Abstract
Gas-phase ion/ion chemistry was coupled to ion mobility/mass spectrometry analysis to correlate the structure of gaseous ubiquitin to its solution structures with selective covalent structural probes. Collision cross section (CCS) distributions were measured to ensure the ubiquitin ions were not unfolded when they were introduced to the gas phase. Aqueous solutions stabilizing the native state of ubiquitin yielded folded ubiquitin structures with CCS values consistent with previously published literature. Denaturing solutions favored several families of unfolded conformations for most of the charge states evaluated. Gas-phase covalent labeling via ion/ion reactions was followed by collision-induced dissociation of the intact, labeled protein to determine which residues were labeled. Ubiquitin 5+ and 6+ electrosprayed from aqueous conditions were covalently modified preferentially at the lysine 29 and arginine 54 positions, indicating that elements of three-dimensional structure were maintained in the gas phase. On the other hand, most ubiquitin ions produced in denaturing conditions were labeled at various other lysine residues, likely due to the availability of additional sites following methanol- and low-pH-induced unfolding. These data support the conservation of ubiquitin structural elements in the gas phase. The research presented here provides the basis for residue-specific characterization of biomolecules in the gas phase.

Abstract
ADP-ribosylation refers to the transfer of the ADP-ribose group from NAD(+) to target proteins post-translationally, either attached singly as mono(ADP-ribose) (MAR) or in polymeric chains as poly(ADP-ribose) (PAR). Though ADP-ribosylation is therapeutically important, investigation of this protein modification has been limited by a lack of proteomic tools for site identification. Recent work has demonstrated the potential of a tag-based pipeline in which MAR/PAR is hydrolyzed down to phosphoribose, leaving a 212 Dalton tag at the modification site. While the pipeline has been proven effective by multiple groups, a barrier to application has become evident: the enzyme used to transform MAR/PAR into phosphoribose must be purified from the rattlesnake Crotalus adamanteus venom, which is contaminated with proteases detrimental for proteomic applications. Here, we outline the steps necessary to purify snake venom phosphodiesterase I (SVP) and describe two alternatives to SVP-the bacterial Nudix hydrolase EcRppH and human HsNudT16. Importantly, expression and purification schemes for these Nudix enzymes have already been proven, with high-quality yields easily attainable. We demonstrate their utility in identifying ADP-ribosylation sites on Poly(ADP-ribose) Polymerase 1 (PARP1) with mass spectrometry and discuss a structure-based rationale for this Nudix subclass in degrading protein-conjugated ADP-ribose, including both MAR and PAR.

Abstract
ADP-ribosylation is a post-translational modification where single units (mono-ADP-ribosylation) or polymeric chains (poly-ADP-ribosylation) of ADP-ribose are conjugated to proteins by ADP-ribosyltransferases. This post-translational modification and the ADP-ribosyltransferases (also known as PARPs) responsible for its synthesis have been found to play a role in nearly all major cellular processes, including DNA repair, transcription, translation, cell signaling, and cell death. Furthermore, dysregulation of ADP-ribosylation has been linked to diseases including cancers, diabetes, neurodegenerative disorders, and heart failure, leading to the development of therapeutic PARP inhibitors, many of which are currently in clinical trials. The study of this therapeutically important modification has recently been bolstered by the application of mass spectrometry-based proteomics, arguably the most powerful tool for the unbiased analysis of protein modifications. Unfortunately, progress has been hampered by the inherent challenges that stem from the physicochemical properties of ADP-ribose, which as a post-translational modification is highly charged, heterogeneous (linear or branched polymers, as well as monomers), labile, and found on a wide range of amino acid acceptors. In this Perspective, we discuss the progress that has been made in addressing these challenges, including the recent breakthroughs in proteomics techniques to identify ADP-ribosylation sites, and future developments to provide a proteome-wide view of the many cellular processes regulated by ADP-ribosylation.

Abstract
ADP-ribosylation refers to the addition of one or more ADP-ribose units onto protein substrates and this protein modification has been implicated in various cellular processes including DNA damage repair, RNA metabolism, transcription, and cell cycle regulation. This review focuses on a compilation of large-scale proteomics studies that identify ADP-ribosylated proteins and their associated proteins by MS using a variety of enrichment strategies. Some methods, such as the use of a poly(ADP-ribose)-specific antibody and boronate affinity chromatography and NAD(+) analogues, have been employed for decades while others, such as the use of protein microarrays and recombinant proteins that bind ADP-ribose moieties (such as macrodomains), have only recently been developed. The advantages and disadvantages of each method and whether these methods are specific for identifying mono(ADP-ribosyl)ated and poly(ADP-ribosyl)ated proteins will be discussed. Lastly, since poly(ADP-ribose) is heterogeneous in length, it has been difficult to attain a mass signature associated with the modification sites. Several strategies on how to reduce polymer chain length heterogeneity for site identification will be reviewed.

Abstract
We demonstrate a novel method for the identification of poly(ADP-ribose) polymerase-1 (PARP-1) autopoly(ADP-ribosyl)ation sites that is suited to collision induced dissociation (CID) tandem mass spectrometry. By employing phosphodiesterase to remove the majority of the poly(ADP-ribose) (pADPr) modification, we reduce the complexity of tandem mass spectrometric analysis of pADPr-modified tryptic peptides. The simplified ribose-5'-phosphate form of the peptides produce tandem mass spectra by CID that are readily interpreted and enable effective localization of the exact sites of PARP-1-catalyzed poly(ADP-ribosyl)ation. In conjunction with a phosphopeptide-like enrichment strategy that captures the ribose-5'-phosphate peptides, we identified eight novel sites of PARP-1 automodification, confirmed the localization of two sites previously reported, and provided evidence for two additional targeted peptides with ambiguous modification site assignments. Given the simplicity of the approach, the method is readily applicable to analysis of complex samples.

Abstract
Protein ADP-ribosylation, including mono- and poly-ADP-ribosylation, is increasingly recognized to play important roles in various biological pathways. Molecular understanding of the functions of ADP-ribosylation requires the identification of the sites of modification. Although tandem mass spectrometry (MS/MS) is widely recognized as an effective means for determining protein modifications, identification of ADP-ribosylation sites has been challenging due to the labile and hydrophilic nature of the modification. Here we applied precursor ion scanning-triggered MS/MS analysis on a hybrid quadrupole linear ion trap mass spectrometer for selectively detecting ADP-ribosylated peptides and determining the auto-ADP-ribosylation sites of CD38 (cluster of differentiation 38) E226D and E226Q mutants. CD38 is an enzyme that catalyzes the hydrolysis of nicotinamide adenine dinucleotide (NAD) to ADP-ribose. Here we show that NAD can covalently label CD38 E226D and E226Q mutants but not wild-type CD38. In this study, we have successfully identified the D226/Q226 and K129 residues of the two CD38 mutants being the ADP-ribosylation sites using precursor ion scanning hybrid quadrupole linear ion trap mass spectrometry. The results offer insights about the CD38 enzymatic reaction mechanism. The precursor ion scanning method should be useful for identifying the modification sites of other ADP-ribosyltransferases such as poly(ADP-ribose) polymerases.

Abstract
The use of tandem mass spectrometry to identify and characterize sites of protein adenosine diphosphate (ADP) ribosylation will be reviewed. Specifically, we will focus on data acquisition schemes and fragmentation techniques that provide peptide sequence and modification site information. Also discussed are uses of synthetic standards to aid characterization, and an enzymatic method that converts ADP-ribosylated peptides into ribosyl mono phosphorylated peptides making identification amenable to traditional phosphopeptide characterization methods. Finally the potential uses of these techniques to characterize poly ADP-ribosylation sites, and inherent challenges, are addressed.

Abstract
Mono-ADP-ribosylation of arginine is a protein modification in eukaryotic cells regulating protein activity and thereby influencing signal transduction and metabolism. Due to the complexity of the modification and the fragmentation pattern in MS/MS CID experiments, the identification of ADP-ribosylation sites in complex mixtures is difficult. Here we describe a two-step strategy, in the first step enriching and identifying potentially ADP-ribosylated proteins and in the second step identifying the sites of modification by a combination of LC/MS-, LC/MS(E) (MS at elevated fragmentation energy)- and LC/MS/MS experiments. Using this technique we could identify two ADP-ribosylation sites in TNFα digested with trypsin, protease V8 and both proteases and thereby demonstrate the specific ADP-ribosylation of TNFα. In complex samples the detection of ADP-ribosylated peptides requires further enrichment of the modified peptides. We tested various materials routinely used for the isolation of phosphopeptides. IMAC as well as TiO(2) chromatography were successfully applied for the selective enrichment of ADP-ribosylated model peptides.
