Abstract
NarE is an arginine-specific mono-ADP-ribosyltransferase identified in Neisseria meningitidis that requires the presence of iron in a structured cluster for its enzymatic activities. In this study, we show that NarE can perform auto-ADP-ribosylation. This automodification occurred in a time- and NAD-concentration-dependent manner; was inhibited by novobiocin, an ADP-ribosyltransferase inhibitor; and did not occur when NarE was heat inactivated. No reduction in incorporation was evidenced in the presence of high concentrations of ATP, GTP, ADP-ribose, or nicotinamide, which inhibits NAD-glycohydrolase, impeding the formation of free ADP-ribose. Based on the electrophoretic profile of NarE on auto-ADP-ribosylation and on the results of mutagenesis and mass spectrometry analysis, the auto-ADP-ribosylation appeared to be restricted to the addition of a single ADP-ribose. Chemical stability experiments showed that the ADP-ribosyl linkage was sensitive to hydroxylamine, which breaks ADP-ribose-arginine bonds. Site-directed mutagenesis suggested that the auto-ADP-ribosylation site occurred preferentially on the R(7) residue, which is located in the region I of the ADP-ribosyltransferase family. After auto-ADP-ribosylation, NarE showed a reduction in ADP-ribosyltransferase activity, while NAD-glycohydrolase activity was increased. Overall, our findings provide evidence for a novel intramolecular mechanism used by NarE to regulate its enzymatic activities.

Abstract
Over 100 years after its first discovery, several new aspects of the biology of the redox co-factor NAD are rapidly emerging. NAD, as well as its precursors, its derivatives, and its metabolic enzymes, have been recently shown to play a determinant role in a variety of biological functions, from the classical role in oxidative phosphorylation and redox reactions to a role in regulation of gene transcription, lifespan and cell death, from a role in neurotransmission to a role in axon degeneration, and from a function in regulation of glucose homeostasis to that of control of circadian rhythm. It is also becoming clear that this variety of specialized functions is regulated by the fine subcellular localization of NAD, its related nucleotides and its metabolic enzymatic machinery. Here we describe the known NAD biosynthetic and catabolic pathways, and review evidence supporting a specialized role for NAD metabolism in a subcellular compartment-dependent manner.

Intra-mitochondrial poly(ADP-ribosyl)ation: potential role for alpha-ketoglutarate dehydrogenase. Mitochondrion 2009; 9:159-64.

Abstract
Poly(ADP-ribose) polymerase (PARP) is an intracellular enzyme involved in DNA repair and in building poly-ADP-ribose polymers on nuclear proteins using NAD(+). While the majority of PARP resides in the nucleus, several studies indicated that PARP may also be located in the cytosol or in the mitochondrial matrix. In this study we found several poly-ADP-ribosylated proteins in isolated rat liver mitochondria following hydrogen peroxide (H(2)O(2)) or nitric oxide donor treatment. Protein poly-ADP-ribosylation was more intense in isolated mitochondria than in whole tissue homogenates and it was not associated with increased nuclear PARP activity. We identified five poly-ADP-ribose (PAR) positive mitochondrial bands by protein mass fingerprinting. All of the identified enzymes exhibited decreased activity or decreased levels following oxidative or nitrosative stress. One of the identified proteins is dihydrolipoamide dehydrogenase (DLDH), a component of the alpha-ketoglutarate dehydrogenase (KGDH) complex, which uses NAD(+) as a substrate. This raised the possibility that KGDH may have a PARP-like enzymatic activity. The intrinsic PARP activity of KGDH and DLDH was confirmed using a colorimetric PARP assay kit and by the incubation of the recombinant enzymes with H(2)O(2). The KGDH enzyme may, therefore, have a novel function as a PARP-like enzyme, which may play a role in regulating intramitochondrial NAD(+) and poly(ADP-ribose) homeostasis, with possible roles in physiology and pathophysiology.

Abstract
Pseudomonas aeruginosa Exoenzyme S (ExoS) is a bifunctional type-III cytotoxin. The N terminus possesses a Rho GTPase-activating protein (GAP) activity, whereas the C terminus comprises an ADP-ribosyltransferase domain. We investigated whether the ADP-ribosyltransferase activity of ExoS influences its GAP activity. Although the ADP-ribosyltransferase activity of ExoS is dependent upon FAS, a 14-3-3 family protein, factor-activating ExoS (FAS) had no influence on the activity of the GAP domain of ExoS (ExoS-GAP). In the presence of NAD and FAS, the GAP activity of full-length ExoS was reduced about 10-fold, whereas NAD and FAS did not affect the activity of the ExoS-GAP fragment. Using [(32)P]NAD, ExoS-GAP was identified as a substrate of the ADP-ribosyltransferase activity of ExoS. Site-directed mutagenesis revealed that auto-ADP-ribosylation of Arg-146 of ExoS was crucial for inhibition of GAP activity in vitro. To reveal the auto-ADP-ribosylation of ExoS in intact cells, tetanolysin was used to produce pores in the plasma membrane of Chinese hamster ovary (CHO) cells to allow the intracellular entry of [(32)P]NAD, the substrate for ADP-ribosylation. After a 3-h infection of CHO cells with Pseudomonas aeruginosa, proteins of 50 and 25 kDa were preferentially ADP-ribosylated. The 50-kDa protein was determined to be auto-ADP-ribosylated ExoS, whereas the 25-kDa protein appeared to represent a group of proteins that included Ras.

Abstract
NAD glycohydrolases are enzymes that catalyze the hydrolysis of NAD to produce ADP-ribose and nicotinamide. Regulation of these enzymes has not been fully elucidated. We have identified a NAD-glycohydrolase activity associated with the outer surface of the plasma membrane in human lung epithelial cell line A549. This activity is negatively regulated by its substrate beta-NAD but not by alpha-NAD. Partial restoration of NADase activity after incubation of the cells with arginine or histidine, known ADP-ribose acceptors, suggests that inhibition be regulated by ADP-ribosylation. A549 do not undergo to apoptosis upon NAD treatment indicating that this effect be likely mediated by a cellular component(s) lacking in epithelial cells.

Abstract
Cyclic ADP-ribose (cADPR), a product of CD38, has a second messenger role for in intracellular Ca(2+) mobilization from microsomes of pancreatic islets as well as from a variety of other cells. ADP-ribosylation of CD38 by ecto-mono ADP-ribosyltransferase in activated T cells results in apoptosis as well as inactivation of its activities. We, therefore, examined the effect of ADP-ribosylation of CD38 in mouse pancreatic islet cells. NAD-dependent inactivation and ADP-ribosylation of CD38, intracellular concentrations of cADPR and Ca(2+), and insulin secretion were measured following incubation of mouse pancreatic islet cells with NAD. ADP-ribosylation of CD38 inactivated its ecto-enzyme activities, and abolished glucose-induced increase of cADPR production, intracellular concentration of Ca(2+), and insulin secretion. Taken together, ecto-cyclase activity of CD38 to produce intracellular cADPR seems to be indispensable for insulin secretion.

Abstract
CD38 is a bifunctional ectoenzyme predominantly expressed on hematopoietic cells where its expression correlates with differentiation and proliferation. The two enzyme activities displayed by CD38 are an ADP-ribosyl cyclase and a cyclic adenosine diphosphate ribose (cADPR) hydrolase that catalyzes the synthesis and hydrolysis of cADPR. T lymphocytes can be induced to express CD38 when activated with antibodies against specific antigen receptors. If the activated T cells are then exposed with NAD, cell death by apoptosis occurs. During the exposure of activated T cells to NAD, the CD38 is modified by ecto-mono-ADP-ribosyltransferases (ecto-mono-ADPRTs) specific for cysteine and arginine residues. Arginine-ADP-ribosylation results in inactivation of both cyclase and hydrolase activities of CD38, whereas cysteine-ADP-ribosylation results only in the inhibition of the hydrolase activity. The arginine-ADP-ribosylation causes a decrease in intracellular cADPR and a subsequent decrease in Ca(2+) influx, resulting in apoptosis of the activated T cells. Our results suggest that the interaction of two classes of ecto-ADP-ribose transfer enzymes plays an important role in immune regulation by the selective induction of apoptosis in activated T cells and that cADPR mediated signaling is essential for the survival of activated T cells.

Abstract
Mono-ADP-ribosylation, a post-translational modification in which the ADP-ribose moiety of NAD is transferred to an acceptor protein, is catalyzed by a family of amino acid-specific ADP-ribosyltransferases. ADP-ribosyltransferase 5 (ART5), a murine transferase originally isolated from Yac-1 lymphoma cells, differed in properties from previously identified eukaryotic transferases in that it exhibited significant NAD glycohydrolase (NADase) activity. To investigate the mechanism of regulation of transferase and NADase activities, ART5 was synthesized as a FLAG fusion protein in Escherichia coli. Agmatine was used as the ADP-ribose acceptor to quantify transferase activity. ART5 was found to be primarily an NADase at 10 microM NAD, whereas at higher NAD concentrations (1 mM), after some delay, transferase activity increased, whereas NADase activity fell. This change in catalytic activity was correlated with auto-ADP-ribosylation and occurred in a time- and NAD concentration-dependent manner. Based on the change in mobility of auto-ADP-ribosylated ART5 by SDS-polyacrylamide gel electrophoresis, the modification appeared to be stoichiometric and resulted in the addition of at least two ADP-ribose moieties. Auto-ADP-ribosylated ART5 isolated after incubation with NAD was primarily a transferase. These findings suggest that auto-ADP-ribosylation of ART5 was stoichiometric, resulted in at least two modifications and converted ART5 from an NADase to a transferase, and could be one mechanism for regulating enzyme activity.

Abstract
NAD glycohydrolase (NADase; EC 3.2.2.5) is an enzyme that catalyzes hydrolysis of NAD to produce ADP-ribose and nicotinamide. We recently demonstrated that self-inactivation of NADase from rabbit erythrocytes was due to an auto-ADP-ribosylation. In the present study, a mechanism of self-inactivation of NADase from Neurospora crassa by its substrate was investigated by using intact mycelia of N. crassa and purified NADase, which had molecular characteristics different from mammalian NADases. The results suggested that inactivation of NADase from N. crassa was also due to an auto-ADP-ribosylation. These findings indicate that the auto-modification of NADase is one of the universal phenomena to regulate enzyme functions.

Abstract
The leucoyte surface antigen CD38 has been shown to be an ecto-enzyme with multiple catalytic activities. It is principally a NAD+ glycohydrolase that transforms NAD+ into ADP-ribose and nicotinamide. CD38 is also able to produce small amounts of cyclic ADP-ribose (ADP-ribosyl cyclase activity) and to hydrolyse this cyclic metabolite into ADP-ribose (cyclic ADP-ribose hydrolase activity). To classify CD38 among the enzymes that transfer the ADP-ribosyl moiety of NAD+ to a variety of acceptors, we have investigated its substrate specificity and some characteristics of its kinetic and molecular mechanisms. We find that CD38-catalysed cleavage of the nicotinamide-ribose bond results in the formation of an E.ADP-ribosyl intermediary complex, which is common to all reaction pathways; this intermediate reacts (1) with acceptors such as water (hydrolysis), methanol (methanolysis) or pyridine (transglycosidation), and (2) intramolecularly, yielding cyclic ADP-ribose with a low efficiency. This reaction scheme is also followed when using nicotinamide guanine dinucleotide as an alternative substrate; in this case, however, the cyclization process is highly favoured. The results obtained here are not compatible with the prevailing model for the mode of action of CD38, according to which this enzyme produces first cyclic ADP-ribose which is then immediately hydrolysed into ADP-ribose (i.e. sequential ADP-ribosyl cyclase and cyclic ADP-ribose hydrolase activities). We show instead that the cyclic metabolite was a reaction product of CD38 rather than an obligatory reaction intermediate during the glycohydrolase activity. Altogether our results lead to the conclusion that CD38 is an authentic 'classical' NAD(P)+ glycohydrolase (EC 3.2.2.6).

Abstract
CD38, a lymphocyte differentiation antigen, is also a bifunctional enzyme catalyzing the synthesis of cyclic ADP-ribose (cADPR) from NAD+ and its hydrolysis to ADP-ribose (ADPR). An additional enzymatic activity of CD38 shared by monofunctional ADP-ribosyl cyclase from Aplysia californica is the exchange of the base group of NAD+ (nicotinamide) with various nucleophiles. Both human CD38 (either recombinant or purified from erythrocyte membranes) and Aplysia cyclase were found to catalyze the exchange of ADPR with the nicotinamide group of NAD+ leading to the formation of a dimeric ADPR ((ADPR)2). The dimeric structure of the enzymatic product, which was generated by recombinant CD38 and by CD38(+) Namalwa cells from as low as 10 microM NAD+, was demonstrated using specific enzyme treatments (dinucleotide pyrophosphatase and 5'-nucleotidase) and mass spectrometry analyses of the resulting products. The linkage between the two ADPR units of (ADPR)2 was identified as that between the N1 of the adenine nucleus of one ADPR unit and the anomeric carbon of the terminal ribose of the second ADPR molecule by enzymatic analyses and by comparison with patterns of cADPR cleavage with Me2SO:tert-butoxide. Although (ADPR)2 itself did not release Ca2+ from sea urchin egg microsomal vesicles, it specifically potentiated the Ca2+-releasing activity of subthreshold concentrations of cADPR. Therefore, (ADPR)2 is a new product of CD38 that amplifies the Ca2+-mobilizing activity of cADPR.
