A novel interaction mechanism accounting for different acylphosphatase effects on cardiac and fast twitch skeletal muscle sarcoplasmic reticulum calcium pumps. (1/700)

In cardiac and skeletal muscle Ca2+ translocation from cytoplasm into sarcoplasmic reticulum (SR) is accomplished by different Ca2+-ATPases whose functioning involves the formation and decomposition of an acylphosphorylated phosphoenzyme intermediate (EP). In this study we found that acylphosphatase, an enzyme well represented in muscular tissues and which actively hydrolyzes EP, had different effects on heart (SERCA2a) and fast twitch skeletal muscle SR Ca2+-ATPase (SERCA1). With physiological acylphosphatase concentrations SERCA2a exhibited a parallel increase in the rates of both ATP hydrolysis and Ca2+ transport; in contrast, SERCA1 appeared to be uncoupled since the stimulation of ATP hydrolysis matched an inhibition of Ca2+ pump. These different effects probably depend on phospholamban, which is associated with SERCA2a but not SERCA1. Consistent with this view, the present study suggests that acylphosphatase-induced stimulation of SERCA2a, in addition to an enhanced EP hydrolysis, may be due to a displacement of phospholamban, thus to a removal of its inhibitory effect.  (+info)

Characterization of the nucleoside triphosphatase activity of poliovirus protein 2C reveals a mechanism by which guanidine inhibits poliovirus replication. (2/700)

The highly conserved non-structural protein 2C of picornaviruses is involved in viral genome replication and encapsidation and in the rearrangement of intracellular structures. 2C binds RNA, has nucleoside triphosphatase activity, and shares three motifs with superfamily III helicases. Motifs "A" and "B" are involved in nucleotide triphosphate (NTP) binding and hydrolysis, whereas a function for motif "C" has not yet been demonstrated. Poliovirus RNA replication is inhibited by millimolar concentrations of guanidine hydrochloride (GdnHCl). Resistance and dependence to GdnHCl map to 2C. To characterize the nucleoside triphosphatase activity of 2C, we purified poliovirus recombinant 2C fused to glutathione S-transferase (GST-2C) from Escherichia coli. GST-2C hydrolyzed ATP with a Km of 0.7 mM. Other NTPs, including GTP, competed with ATP for binding to 2C but were poor substrates for hydrolysis. Mutation of conserved residues in motif A and B abolished ATPase activity, as did mutation of the conserved asparagine residue in motif C, an observation indicating the involvement of this motif in ATP hydrolysis. GdnHCl at millimolar concentrations inhibited ATP hydrolysis. Mutations in 2C that confer poliovirus resistant to or dependent on GdnHCl increased the tolerance to GdnHCl up to 100-fold.  (+info)

The serine protease and RNA-stimulated nucleoside triphosphatase and RNA helicase functional domains of dengue virus type 2 NS3 converge within a region of 20 amino acids. (3/700)

NS3 protein of dengue virus type 2 has a serine protease domain within the N-terminal 180 residues. NS2B is required for NS3 to form an active protease involved in processing of the viral polyprotein precursor. The region carboxy terminal to the protease domain has conserved motifs present in several viral RNA-stimulated nucleoside triphosphatase (NTPase)/RNA helicases. To define the functional domains of protease and NTPase/RNA helicase activities of NS3, full-length and amino-terminal deletion mutants of NS3 were expressed in Escherichia coli and purified. Deletion of 160 N-terminal residues of NS3 (as in NS3del.2) had no detrimental effect on the basal and RNA-stimulated NTPase as well as RNA helicase activities. However, mutagenesis of the conserved P-loop motif of the RNA helicase domain (K199E) resulted in loss of ATPase activity. The RNA-stimulated NTPase activity was significantly affected by deletion of 20 amino acid residues from the N terminus or by substitutions of the cluster of basic residues, 184RKRK-->QNGN, of NS3del.2, although both mutant proteins retained the conserved RNA helicase motifs. Furthermore, the minimal NS3 protease domain, required for cleavage of the 2B-3 site, was precisely defined to be 167 residues, using the in vitro processing of NS2B-NS3 precursors. Our results reveal that the functional domains required for serine protease and RNA-stimulated NTPase activities map within the region between amino acid residues 160 and 180 of NS3 protein and that a novel motif, the cluster of basic residues 184RKRK, plays an important role for the RNA-stimulated NTPase activity.  (+info)

The Saccharomyces cerevisiae YOR163w gene encodes a diadenosine 5', 5"'-P1,P6-hexaphosphate (Ap6A) hydrolase member of the MutT motif (Nudix hydrolase) family. (4/700)

The YOR163w open reading frame on chromosome XV of the Saccharomyces cerevisiae genome encodes a member of the MutT motif (nudix hydrolase) family of enzymes of Mr 21,443. By cloning and expressing this gene in Escherichia coli and S. cerevisiae, we have shown the product to be a (di)adenosine polyphosphate hydrolase with a previously undescribed substrate specificity. Diadenosine 5',5"'-P1, P6-hexaphosphate is the preferred substrate, and hydrolysis in H218O shows that ADP and adenosine 5'-tetraphosphate are produced by attack at Pbeta and AMP and adenosine 5'-pentaphosphate are produced by attack at Palpha with a Km of 56 microM and kcat of 0.4 s-1. Diadenosine 5',5"'-P1,P5-pentaphosphate, adenosine 5'-pentaphosphate, and adenosine 5'-tetraphosphate are also substrates, but not diadenosine 5',5"'-P1,P4-tetraphosphate or other dinucleotides, mononucleotides, nucleotide sugars, or nucleotide alcohols. The enzyme, which was shown to be expressed in log phase yeast cells by immunoblotting, displays optimal activity at pH 6.9, 50 degrees C, and 4-10 mM Mg2+ (or 200 microM Mn2+). It has an absolute requirement for a reducing agent, such as dithiothreitol (1 mM), and is inhibited by Ca2+ with an IC50 of 3.3 mM and F- (noncompetitively) with a Ki of 80 microM. Its function may be to eliminate potentially toxic dinucleoside polyphosphates during sporulation.  (+info)

Characterization and mutational analysis of the helicase and NTPase activities of hepatitis C virus full-length NS3 protein. (5/700)

The non-structural protein 3 (NS3) of hepatitis C virus (HCV) possesses three activities which are likely to be essential for virus replication; a serine protease located in the N terminus and helicase and NTPase activities located in the C terminus. Sequence analysis of the helicase/NTPase domain has identified motifs indicative of the DEAD-box family of helicases. Here we present the characterization of the helicase and NTPase activities of full-length NS3, expressed as a His-tagged fusion protein in E. coli, and make comparisons with published data of NS3 helicase domain alone. The helicase and NTPase activities of full-length NS3 have been demonstrated and we have characterized the effects of amino acid substitutions on conserved motifs of NS3 helicase. Helicase and NTPase activities were dependent on Mg2+ and ATP and inhibited by monovalent cations. NS3 was able to hydrolyse all four NTPs and dNTPs to drive DNA duplex unwinding but with differing abilities. NTPase activity was stimulated by all polynucleotides tested, with poly(U) having the greatest effect. Mutational analysis of conserved motifs of NS3 helicase showed all conserved residues to be required for optimal activity. These results are in accord with a recently proposed model for NS3 helicase activity.  (+info)

The FHIT gene is expressed in pancreatic ductular cells and is altered in pancreatic cancers. (6/700)

We examined 2 normal pancreata, 21 primary pancreatic ductal cancers, and 19 pancreatic cancer cell lines for Fhit expression and FHIT gene status. The normal pancreas expressed Fhit protein in the cytoplasm of ductular cells, whereas interlobular and larger ducts, acini, and insulae of Langerhans were negative. Fhit protein was detected by immunoblot assay in 11 pancreatic cancer cell lines; of the 8 cell lines lacking Fhit protein, 7 lacked FHIT mRNA and 1 showed an abnormally sized transcript. DNA from five of these eight cell lines showed homozygous loss of FHIT exon 5. In 8 of the 21 primary cancers, Fhit expression was detected by immunohistochemistry. Reverse transcription-PCR analysis of 6 of the 13 cases lacking Fhit showed normal-sized FHIT product in 3 cases and a mixture of normal and abnormal products in the other 3. Sequencing showed that abnormal bands were missing variable numbers of exons. Loss of microsatellite DNA markers internal to the FHIT gene was observed in 10 of 13 primary cancers lacking Fhit protein (homozygous in two cases) and in only 1 of the 8 cancers expressing Fhit protein. In nine primary cancers, four expressing and five lacking Fhit protein, it was possible to obtain pure cancer DNA by microdissection. Three of the five microdissected cases lacking Fhit protein exhibited homozygous deletion of FHIT exon 5. In conclusion, the lack of Fhit protein in pancreatic cancers correlated with absence or alteration of FHIT mRNA and was often associated with FHIT gene anomalies.  (+info)

Loss of heterozygosity at 3p14.2 in clear cell renal cell carcinoma is an early event and is highly localized to the FHIT gene locus. (7/700)

The VHL tumor suppressor gene (TSG) at 3p25-26 is strongly implicated in the pathogenesis of clear cell renal cell carcinoma (cRCC). In addition, 3p14.2 and 3p21 are suspected of harboring additional TSGs in cRCC, with FHIT being a candidate TSG at 3p14.2. We examined 87 microdissected, histologically well-defined cRCCs classified according to tumor-node-metastasis (TNM) stage (stage 1, 23 cases; stage 2, 14 cases; stage 3, 24 cases; stage 4, 26 cases) and Fuhrman grade (grade 1, 24 cases; grade 2, 19 cases; grade 3, 19 cases; grade 4, 8 cases; sarcomatoid cRCC, 17 cases) for loss of heterozygosity (LOH) at 3p14.2 and 3p25-26 using a series of precisely mapped microsatellite probes. We found that LOH at 3p14.2 exceeded LOH at 3p25-26 in frequency (69% versus 48.3%; P < 0.03) and was highly localized to markers within the FHIT gene locus (D3S1300 and D3S4260), with the majority of chromosomal breakpoints also mapping to this region. In addition, 3p14.2 LOH (P < 0.03), but not 3p25-26 LOH (P = nonsignificant), was associated with lower tumor grades (grades 1-3). These findings suggest that 3p14.2 genomic deletions may be among the earliest events in cRCC pathogenesis, preceding genomic deletions at the VHL locus. FHIT, or an as yet undiscovered TSG mapping to the D3S4103-D3S4260 interval, could be the molecular target of the 3p14.2 deletions.  (+info)

Designing conditions for in vitro formation of amyloid protofilaments and fibrils. (8/700)

We have been able to convert a small alpha/beta protein, acylphosphatase, from its soluble and native form into insoluble amyloid fibrils of the type observed in a range of pathological conditions. This was achieved by allowing slow growth in a solution containing moderate concentrations of trifluoroethanol. When analyzed with electron microscopy, the protein aggregate present in the sample after long incubation times consisted of extended, unbranched filaments of 30-50 A in width that assemble subsequently into higher order structures. This fibrillar material possesses extensive beta-sheet structure as revealed by far-UV CD and IR spectroscopy. Furthermore, the fibrils exhibit Congo red birefringence, increased fluorescence with thioflavine T and cause a red-shift of the Congo red absorption spectrum. All of these characteristics are typical of amyloid fibrils. The results indicate that formation of amyloid occurs when the native fold of a protein is destabilized under conditions in which noncovalent interactions, and in particular hydrogen bonding, within the polypeptide chain remain favorable. We suggest that amyloid formation is not restricted to a small number of protein sequences but is a property common to many, if not all, natural polypeptide chains under appropriate conditions.  (+info)

We have shown: (a) that adenoviral vector-mediated overexpression of the wild-type FHIT gene efficiently inhibited growth of tumor cells of varying FHIT gene and gene product status in vitro; (b) that the tumorigenicity of the Ad-FHIT-transduced tumor cells was eliminated in vivo; and (c) that tumor growth was significantly suppressed by direct injection of the FHIT-expressing adenoviral vector into s.c. tumors in nude mice. These results provided direct evidence for the biological function of FHIT as a tumor suppressor gene both in vitro and in vivo.. The lung cancer cell lines H1299, A549, and H460 and the head and neck carcinoma cell line 1483 all exhibit an altered or inactivated FHIT gene, as shown by reverse transcription-PCR and Northern blot analysis (7 , 9 , 18) , lack endogenous Fhit protein expression, as shown by Western blot analysis, and are highly tumorigenic. Alterations in the FHIT locus have been shown to be correlated with loss or reduction of Fhit protein expression in tumors ...
In this study, we have demonstrated that 44% of colorectal cancers have markedly reduced expression of Fhit protein. A similar reduction of Fhit protein expression has been reported in other human tumors such as lung (4) , cervical (12) , renal (11) , pancreatic (10) , head and neck (6) , and breast (5) carcinomas. The frequent loss of Fhit protein expression, the expression of aberrant FHIT transcripts, and numerous deletions within the FHIT gene suggest that FHIT is a candidate suppressor gene common to many cancers (reviewed in Ref. 1 ). In addition to the loss of Fhit protein expression, our studies found additional evidence that suggests that Fhit is important in colon tumorigenesis. A trend of increased proportions of colorectal cancers expressed reduced levels of Fhit (a) with decreasing degrees of differentiation, (b) with more advanced stages (Dukes stage C and D) compared with less advanced stages (Dukes stage A and B) of primary tumors, and (c) in metastatic lesions compared with ...

The tumour suppressor gene FHIT, encompassing the FRA3B fragile web page on chromosome 3p14. two, is a lot more than 1 Mb in size and encodes to get a one. 1 kb cDNA. It belongs for the histidine triad superfamily and encodes a cytoplasmic 16. eight kDa protein. Epithelial cells in many human tissues strongly express Fhit protein, though Fhit expression is absent or decreased inside a massive fraction of tumours. Fhit protein reduction or absence takes place in 70% of breast cancer specimens, suggesting that alter ation of Fhit expression on this tumour is really a regular occasion, brought on by each alterations while in the regulation of Fhit expression and from the very well documented biallelic deletion of the gene. To determine how Fhit down regulation influ ences breast cancer progression, we have examined protein expression at various phases with the sickness.. Commencing from usual epithelia, we now have also considered morphological lesions of various grades, such as atypical ductal ...
Lung cancer is a leading cause of cancer death among men and women in industrialized countries. Small cell lung carcinoma (SCLC) is a highly aggressive neoplasm, which accounts for approximately 25% of all lung cancer cases. Molecular mechanisms altered in SCLC include induced expression of oncogene, MYC, and loss of tumorsuppressor genes, such as p53, PTEN, RB, and FHIT. The overexpression of MYC proteins in SCLC is largely a result of gene amplification. Such overexpression leads to more rapid proliferation and loss of terminal differentiation. Mutation or deletion of p53 or PTEN can lead to more rapid proliferation and reduced apoptosis. The retinoblastoma gene RB1 encodes a nuclear phosphoprotein that helps to regulate cell-cycle progression. The fragile histidine triad gene FHIT encodes the enzyme diadenosine triphosphate hydrolase, which is thought to have an indirect role in proapoptosis and cell-cycle control ...

RNA triphosphatase is an essential mRNA processing enzyme that catalyzes the first step in cap formation. The 2.05 A crystal structure of yeast RNA triphosphatase Cet1p reveals a novel active site fold whereby an eight-stranded beta barrel forms a topologically closed triphosphate tunnel. Interactions of a sulfate in the center of the tunnel with a divalent cation and basic amino acids projecting into the tunnel suggest a catalytic mechanism that is supported by mutational data. Discrete surface domains mediate Cet1p homodimerization and Cet1p binding to the guanylyltransferase component of the capping apparatus. The structure and mechanism of fungal RNA triphosphatases are completely different from those of mammalian mRNA capping enzymes. Hence, RNA triphosphatase presents an ideal target for structure-based antifungal drug discovery ...
Addition of acylphosphatase exerted a stimulating effect on the alcoholic fermentation of glucose by Saccharomyces cerevisiae. The rates of glucose degradation and ethanol production by cell-free extracts of the S-288C strain were measured in the absence and in the presence of various levels of this enzyme. Two acylphosphatase isoenzymes were used; one was purified from horse skeletal muscle and the other from human erythrocytes. Both increased the rate of alcoholic fermentation, but that from erythrocytes proved to be the more efficient. This stimulating action is probably due to an uncoupling effect of acylphosphatase on the fermentative process, through hydrolysis of 3-phosphoglyceroyl phosphate. This was demonstrated by the fact that alcoholic fermentation was stimulated considerably by a mixture of ADP and inorganic phosphate and by arsenate as well. The possibility of improving the fermentative capacity of microorganisms may have important biotechnological applications.. ...

Purified fractions of cytosol, vacuoles, nuclei, and mitochondria of Saccharomyces cerevisiae possessed inorganic polyphosphates with chain lengths characteristic of each individual compartment. The most part (80-90%) of the total polyphosphate level was found in the cytosol fractions. Inactivation of a PPX1 gene encoding ∼40-kDa exopolyphosphatase substantially decreased exopolyphosphatase activities only in the cytosol and soluble mitochondrial fraction, the compartments where PPX1 activity was localized. This inactivation slightly increased the levels of polyphosphates in the cytosol and vacuoles and had no effect on polyphosphate chain lengths in all compartments. Exopolyphosphatase activities in all yeast compartments under study critically depended on the PPN1 gene encoding an endopolyphosphatase. In the single PPN1 mutant, a considerable decrease of exopolyphosphatase activity was observed in all the compartments under study. Inactivation of PPN1 decreased the polyphosphate level in the ...

Diadenosine triphosphate is present in platelet-dense granules and released quantitatively on platelet aggregation. We have found that intact porcine aortic endothelial cells can efficiently hydrolyze extracellular diadenosine triphosphate. The products of diadenosine triphosphate hydrolysis are adenosine monophosphate and adenosine diphosphate. Adenosine diphosphate is a potent stimulus of platelet aggregation. Since platelet-dense granules contain high concentrations of adenosine triphosphate and adenosine diphosphate, we examined endothelial cell hydrolysis of a mixture of diadenosine triphosphate and adenosine triphosphate. We find that the presence of adenosine triphosphate severely inhibits the hydrolysis of diadenosine triphosphate. Thus, although endothelial cells can rapidly clear extracellular diadenosine triphosphate, during platelet aggregation the hydrolysis of diadenosine triphosphate may be slow due to the presence of high concentrations of other adenine nucleotides. This ...
Exopolyphosphatases and pyrophosphatases play important but still incompletely understood roles in energy metabolism, and also in other aspects of cell biology such as osmoregulation or signal transduction. Earlier work has suggested that a human exopolyphosphatase, Prune, might exhibit cyclic nucleotide phosphodiesterase activity. The kinetoplastida, a large order of unicellular eukaryotes that contains many important pathogens such as Trypanosoma brucei (human sleeping sickness), Trypanosoma cruzi (Chagas disease) or Leishmania ssp (several clinically dinstinct leishmaniases) all contain several exo- and pyrophosphatases. The current study provides a systematic classification of these enzymes, which now allows to situate the information that is already available on some of these enzymes. It then analyses the exopolyphosphatase TbrPPX1 of T. brucei in detail, using RNA interference and genetic knockouts in an attempt to define its function, and immunofluorescence microscopy to study its subcellular
Aberrant Fhit expression characterizes a large proportion of primary pancreatic ductal adenocarcinomas (PDACs), but fragmentary information is available on Fhit expression during the phenotypic changes of pancreatic ductal epithelium during multistep transformation. We assessed Fhit expression by immunohistochemistry in two different multistep pancreatic carcinogenic processes: pancreatic intraepithelial neoplasia (PanIN) and intraductal papillary mucinous neoplasia (IPMN). We considered 105 surgically treated PDACs/IPMNs and selected 30 samples of non-neoplastic pancreatic parenchyma, 50 PanIN lesions, 30 IPMNs, 15 IPMNs with associated invasive carcinoma, and 60 adenocarcinomas. Normal pancreatic ducts and surrounding acinar cells consistently showed moderate to strong Fhit immunoreactivity. Significant down-regulation of Fhit expression was observed in association with increasing severity of dysplastia/neoplastia in both carcinogenic processes. This was further confirmed by studying multiple ...

The complement system is critical for immunity against the important human pathogen Neisseria meningitidis. We describe the isolation of a meningococcal mutant lacking PPX, an exopolyphosphatase responsible for cleaving cellular polyphosphate, a polymer of tens to hundreds of orthophosphate residues found in virtually all living cells. Bacteria lacking PPX exhibit increased resistance to complement-mediated killing. By site directed mutagenesis, we define amino acids necessary for the biochemical activity of meningococcal PPX, including a conserved glutamate (Glu(117)) and residues in the Walker B box predicted to be involved in binding to phosphate. We show that the biochemical activity of PPX is necessary for interactions with the complement. The relative resistance of the ppx mutant does not result from changes in structures (such as capsule, lipopolysaccharide, and factor H-binding protein), which are known to be required for evasion of this key aspect of host immunity. Instead, expression of PPX
TY - JOUR. T1 - Characterisation of a bis(5-nucleosyl)-tetraphosphatase (asymmetrical) from Drosophila melanogaster. AU - Winward, Lucinda. AU - Whitfield, William G. F.. AU - Woodman, Timothy J. AU - McLennan, Alexander G.. AU - Safrany, Stephen T.. PY - 2007. Y1 - 2007. N2 - The intracellular functions of diadenosine polyphosphates are still poorly defined. To understand these better, we have expressed and characterized a heat stable, 16.6kDa Nudix hydrolase (Apf) that specifically metabolizes these nucleotides from a Drosophila melanogaster cDNA. Apf always produces an NTP product, with substrate preference depending on pH and divalent ion (Zn(2+) or Mg(2+)). For example, diadenosine tetraphosphate is hydrolysed to ATP and AMP with K(m), k(cat) and k(cat)/K(m) values 9microM, 43s(-1) and 4.8microM(-1)s(-1) (pH 6.5, 0.1mMZn(2+)) and 12microM, 13s(-1) and 1.1microM(-1)s(-1) (pH 7.5, 20mMMg(2+)), respectively. However, diadenosine hexaphosphate is efficiently hydrolysed to ATP only at pH 7.5 ...
The physiological roles of polyphosphates (polyP) recently found in arthropod mitochondria remain obscure. Here, the relationship between the mitochondrial membrane exopolyphosphatase (PPX) and the energy metabolism of hard tick Rhipicephalus microplus embryos are investigated. Mitochondrial respiration was activated by adenosine diphosphate using polyP as the only source of inorganic phosphate (Pi) and this activation was much greater using polyP3 than polyP15. After mitochondrial subfractionation, most of the PPX activity was recovered in the membrane fraction and its kinetic analysis revealed that the affinity for polyP3 was 10 times stronger than that for polyP15. Membrane PPX activity was also increased in the presence of the respiratory substrate pyruvic acid and after addition of the protonophore carbonyl cyanide-p-trifluoromethoxyphenylhydrazone. Furthermore, these stimulatory effects disappeared upon addition of the cytochrome oxidase inhibitor potassium cyanide and the activity was completely
Diadenosine tetraphosphate or Ap4A is a putative alarmone, ubiquitous in nature being common to everything from bacteria to humans. Adenosine polyphosphates are capable of inducing multiple physiological effects. The molecules role as a second messenger has recently been discovered in The LysRS-Ap4A-MITF signaling pathway. *Luo J, Jankowski V, Güngär N, Neumann J, Schmitz W, Zidek W, Schlüter H, Jankowski J (2004).
