Abstract
New players in plant signaling are described in detail in this review: extracellular ATP (eATP) and uncommon nucleotides such as dinucleoside polyphosphates (NpnN's), adenosine 5'-phosphoramidate (NH2-pA), and extracellular NAD+ and NADP+ (eNAD(P)+). Recent molecular, physiological, and biochemical evidence implicating concurrently the signaling role of eATP, NpnN's, and NH2-pA in plant biology and the mechanistic events in which they are involved are discussed. Numerous studies have shown that they are often universal signaling messengers, which trigger a signaling cascade in similar reactions and processes among different kingdoms. We also present here, not described elsewhere, a working model of the NpnN' and NH2-pA signaling network in a plant cell where these nucleotides trigger induction of the phenylpropanoid and the isochorismic acid pathways yielding metabolites protecting the plant against various types of stresses. Through these signals, the plant responds to environmental stimuli by intensifying the production of various compounds, such as anthocyanins, lignin, stilbenes, and salicylic acid. Still, more research needs to be performed to identify signaling networks that involve uncommon nucleotides, followed by omic experiments to define network elements and processes that are controlled by these signals.

Abstract
Fhits (fragile histidine triad proteins) occur in eukaryotes but their function is largely unknown, although human Fhit is believed to act as a tumour suppressor. Fhits also exhibit dinucleoside triphosphatase, adenylylsulfatase and nucleoside phosphoramidase activities that in each case yield nucleoside 5'-monophosphate as a product. Due to the dinucleoside triphosphatase activity, Fhits may also be involved in mRNA decapping. In the present study, we demonstrate Fhit-catalysed ammonolysis of adenosine 5'-phosphosulfate, which results in the formation of adenosine 5'-phosphoramidate. This reaction has previously been associated with adenylylsulfate-ammonia adenylyltransferase (EC 2.7.7.51). Our finding shows that the capacity to catalyse ammonolysis is another inherent property of Fhits. Basic kinetic parameters and substrate specificity of this reaction catalysed by human Fhit are presented.

Abstract
Nudix pyrophosphatases, ubiquitous in all organisms, have not been well studied. Recent implications that some of them may be involved in response to stress and in pathogenesis indicate that they play important biological functions. We have investigated NudC Nudix proteins from the plant pathogen Pseudomonas syringae pv. tomato str. DC3000 and from the human pathogen Pseudomonas aeruginosa PAO1161. We found that these homologous enzymes are homodimeric and in vitro preferentially hydrolyse NADH. The P. syringae mutant strain deficient in NudC accumulated NADH and displayed significant defects in growth, motility and biofilm formation. The wild type copy of the nudC gene with its cognate promoter delivered in trans into the nudC mutant restored its fitness. However, introduction of the P. syringae nudC gene under the control of the strong tacp promoter into either P. syringae or P. aeruginosa cells had a toxic effect on both strains. Opposite to P. syringae NudC, the P. aeruginosa NudC deficiency as well as its overproduction had no visible impact on cells. Moreover, P. aeruginosa NudC does not compensate the lack of its counterpart in the P. syringae mutant. These results indicate that NudC from P. syringae, but not from P. aeruginosa is vital for bacteria.

Abstract
Adenosine 5'-polyphosphates have been identified in vitro, as products of certain enzymatic reactions, and in vivo. Although the biological role of these compounds is not known, there exist highly specific hydrolases that degrade nucleoside 5'-polyphosphates into the corresponding nucleoside 5'-triphosphates. One approach to understanding the mechanism and function of these enzymes is through the use of specifically designed phosphonate analogues. We synthesized novel nucleotides: alpha,beta-methylene-adenosine 5'-tetraphosphate (pppCH2pA), beta,gamma-methylene-adenosine 5'-tetraphosphate (ppCH2ppA), gamma,delta-methylene-adenosine 5'-tetraphosphate (pCH2pppA), alphabeta,gammadelta-bismethylene-adenosine 5'-tetraphosphate (pCH2ppCH2pA), alphabeta, betagamma-bismethylene-adenosine 5'-tetraphosphate (ppCH2pCH2pA) and betagamma, gammadelta-bis(dichloro)methylene-adenosine 5'-tetraphosphate (pCCl2pCCl2ppA), and tested them as potential substrates and/or inhibitors of three specific nucleoside tetraphosphatases. In addition, we employed these p4A analogues with two asymmetrically and one symmetrically acting dinucleoside tetraphosphatases. Of the six analogues, only pppCH2pA is a substrate of the two nucleoside tetraphosphatases (EC 3.6.1.14), from yellow lupin seeds and human placenta, and also of the yeast exopolyphosphatase (EC 3.6.1.11). Surprisingly, none of the six analogues inhibited these p4A-hydrolysing enzymes. By contrast, the analogues strongly inhibit the (asymmetrical) dinucleoside tetraphosphatases (EC 3.6.1.17) from human and the narrow-leafed lupin. ppCH2ppA and pCH2pppA, inhibited the human enzyme with Ki values of 1.6 and 2.3 nm, respectively, and the lupin enzyme with Ki values of 30 and 34 nm, respectively. They are thereby identified as being the strongest inhibitors ever reported for the (asymmetrical) dinucleoside tetraphosphatases. The three analogues having two halo/methylene bridges are much less potent inhibitors for these enzymes. These novel nucleotides should prove valuable tools for further studies on the cellular functions of mono- and dinucleoside polyphosphates and on the enzymes involved in their metabolism.

Abstract
A new methodology for synthesis of biologically important nucleoside tri- and tetraphosphates containing a bisphosphonate moiety instead of the terminal pyrophosphate bond is described. The series consists of tri- and tetraphosphate analogs of adenosine, guanosine and 7-methylguanosine (characteristic for mRNA cap). We have adopted a two-step procedure that allowed us to insert a methylene bridge into the phosphate chain. Nucleoside mono- or diphosphates were first activated (as imidazole derivatives) and then used in coupling reactions with organic salts of bisphosphonate. The resulting synthetic method enabled us to obtain the desired compounds with high yields and does not require any protective groups. This makes it very useful for the synthesis of labile compounds such as those containing the 7-methylguanosine ring. The structures of the synthesized compounds were confirmed by NMR spectroscopy. They were tested as potential substrates and inhibitors of several hydrolases.

Abstract
4-Coumarate:coenzyme A ligase (4CL) is known to activate cinnamic acid derivatives to their corresponding coenzyme A esters. As a new type of 4CL-catalyzed reaction, we observed the synthesis of various mono- and diadenosine polyphosphates. Both the native 4CL2 isoform from Arabidopsis (At4CL2 wild type) and the At4CL2 gain of function mutant M293P/K320L, which exhibits the capacity to use a broader range of phenolic substrates, catalyzed the synthesis of adenosine 5'-tetraphosphate (p(4)A) and adenosine 5'-pentaphosphate when incubated with MgATP(-2) and tripolyphosphate or tetrapolyphosphate (P(4)), respectively. Diadenosine 5',5''',-P(1),P(4)-tetraphosphate represented the main product when the enzymes were supplied with only MgATP(2-). The At4CL2 mutant M293P/K320L was studied in more detail and was also found to catalyze the synthesis of additional dinucleoside polyphosphates such as diadenosine 5',5'''-P(1),P(5)-pentaphosphate and dAp(4)dA from the appropriate substrates, p(4)A and dATP, respectively. Formation of Ap(3)A from ATP and ADP was not observed with either At4CL2 variant. In all cases analyzed, (di)adenosine polyphosphate synthesis was either strictly dependent on or strongly stimulated by the presence of a cognate cinnamic acid derivative. The At4CL2 mutant enzyme K540L carrying a point mutation in the catalytic center that is critical for adenylate intermediate formation was inactive in both p(4)A and diadenosine 5',5''',-P(1),P(4)-tetraphosphate synthesis. These results indicate that the cinnamoyl-adenylate intermediate synthesized by At4CL2 not only functions as an intermediate in coenzyme A ester formation but can also act as a cocatalytic AMP-donor in (di)adenosine polyphosphate synthesis.

Abstract
A cDNA encoding previously purified and characterized diphosphonucleotide phosphatase/phosphodiesterase (PPD1) from yellow lupin (Lupinus luteus L.) was identified. The ppd1 gene encodes a protein containing a cleavable signal sequence. A functional expression of PPD1 in Saccharomyces cerevisiae confirmed the proper gene identification. A gene homologous to ppd1, encoding a putative membrane protein (PPD2), as well as fragments of two other genes encoding PPD3 and PPD4 proteins were also isolated. Amino acids composing the putative active center of PPD1 and PPD2 are similar to those present in known purple acid phosphatases, which suggests that the reported genes might encode a novel group of specific metallophosphatases. RT-PCR revealed that the corresponding PPD1 mRNA accumulates in stems and leaves, and PPD2 mRNA in stems, leaves and seedlings.

Abstract
This review concerns enzymes that can degrade nucleoside 5'-tetra- and pentaphosphates (p(4)N and p(5)N) and those that can degrade various dinucleoside polyphosphates (Np(3-6)N'). Most of these enzymes are hydrolases, and they occur in all types of organisms. Certain fungi and protozoa also possess specific Np(n)N' phosphorylases. Specific p(4)N hydrolases have been demonstrated in mammals and in plants. In yeast, p(4)N and p(5)N are hydrolyzed by exopolyphosphatases. Among other hydrolases that can degrade these minor mononucleotides are phosphatases, apyrase, and (asymmetrical) Np(4)N' hydrolase, as well as the nonspecific adenylate deaminase. Np(n)N's are good substrates for Type I phosphodiesterases and nucleotide pyrophosphatases, and diadenosine polyphosphates are easily deaminated to diinosine polyphosphates by nonspecific adenylate deaminases. Specific Np(3)N' hydrolases occur in both prokaryotes and eukaryotes. Interestingly, the human fragile histidine triad (Fhit) tumor suppressor protein appears to be a typical Np(3)N' hydrolase. Among the specific Np(4)N' hydrolases are asymmetrically cleaving ones, which are typical of higher eukaryotes, and symmetrically cleaving enzymes found in Physarum polycephalum and in many bacteria. An enzyme that hydrolyzes both diadenosine tetraphosphate and diadenosine triphosphate has been found in the fission yeast Schizosaccharomyces pombe. Its amino acid sequence is similar to that of the human Fhit/Np(3)N' hydrolase. Very recently, a typical (asymmetrical) Np(4)N' hydrolase has been demonstrated for the first time in a bacterium-the pathogenic Bartonella bacilliformis. Another novelty is the discovery of diadenosine 5', 5"'-P(1),P 6-hexaphosphate hydrolases in budding and fission yeasts and in mammalian cells. These enzymes and the (asymmetrical) Np(4)N' hydrolases have the amino acid motif typical of the MutT (or Nudix hydrolase) family. In contrast, the Schizosaccharomyces pombe Ap(4)A/Ap(3)A hydrolase, the human Fhit protein, and the yeast Np(n)N' phosphorylases belong to a superfamily GAFH, which includes the histidine triad proteins.

Abstract
A phosphatase cleaving the pyrophosphate bond in diphosphonucleotides and phosphodiester bond in various phosphodiesters (pH optimum at 6.25) was purified from yellow lupin (Lupinus luteus L.) seeds. The enzyme is 75 kDa monomeric glycoprotein (pI=6.4) with 4.4% of carbohydrate (mannose, N-acetylglucosamine, fucose and xylose). Analysis of its partial amino acid sequence (8 peptides, 101 amino acid residues) together with no divalent cation requirements for catalysis points out that the purified enzyme is different from known plant pyrophosphate cleaving enzymes (apyrases and inorganic pyrophosphatases). Its physiological role could be related to a regulation of diphosphonucleotides level in plant metabolism.

Abstract
A nucleotide pyrophosphatase (EC 3.6.1.9) was purified to homogeneity from lentil seedlings. The enzyme is a single polypeptide chain of 75 +/- 2 kDa that exhibits hydrolytic activities toward pyrophosphate linkages of several substrates. Reduced and oxidized forms of NAD(P) were shown to be hydrolyzed to nicotinamide mononucleotide and AMP. Other dinucleotides such as FAD and dinucleoside oligophosphates were hydrolyzed as well, but with lower efficiency. Pyrophosphatase activity was increased in the presence of divalent cations such as Ca2+, Mg2+, and Mn2+, whereas Cu2+, Zn2+, and Ni2+ ions inhibited this activity. The active site in the enzyme was not defined, but histidine residue(s) seemed to be crucial for the enzymatic activity.

Abstract
It is known that the interferon-inducible 2',5'-oligoadenylate synthetase can catalyze the 2'-adenylation of various diadenosine polyphosphates. However, catabolism of those 2'-adenylated compounds has not been investigated so far. This study shows that the mono- and bis-adenylated (or mono- and bis-deoxyadenylated) diadenosine triphosphates are not substrates of the human Fhit (fragile histidine triad) protein, which acts as a typical dinucleoside triphosphate hydrolase (EC 3.6.1.29). In contrast, the diadenosine tetraphosphate counterparts are substrates for the human (asymmetrical) Ap(4)A hydrolase (EC 3.6.1.17). The relative rates of the hydrolysis of 0.15 mM AppppA, (2'-pdA)AppppA, and (2'-pdA)AppppA(2"'-pdA) catalyzed by the latter enzyme were determined as 100:232:38, respectively. The asymmetrical substrate was hydrolyzed to ATP + (2'-pdA)AMP (80%) and to (2'-pdA)ATP + AMP (20%). The human Fhit protein, for which Ap(4)A is a poor substrate, did not degrade the 2'-adenylated diadenosine tetraphosphates either. The preference of the interferon-inducible 2'-5' oligoadenylate synthetase to use Ap(3)A over Ap(4)A as a primer for 2'-adenylation and the difference in the recognition of the 2'-adenylated diadenosine triphosphates versus the 2'-adenylated diadenosine tetraphosphates by the dinucleoside polyphosphate hydrolases described here provide a mechanism by which the ratio of the 2'-adenylated forms of the signalling molecules, Ap(3)A and Ap(4)A, could be regulated in vivo.
