Using genomic information to investigate the function of ThiI, an enzyme shared between thiamin and 4-thiouridine biosynthesis. (1/66)

The gene thiI encodes a protein (ThiI) that plays a role in the transfer of sulfur from cysteine to both thiamin and 4-thiouridine, but the reaction catalyzed by ThiI remains undetermined. Based upon sequence alignments, ThiI shares a unique "P-loop" motif with the PPi synthetase family, four enzymes that catalyze adenylation and subsequent substitution of carbonyl oxygens. To test whether or not this motif is critical for ThiI function, the Asp in the motif was converted to Ala (D189A), and a screen for in vivo 4-thiouridine production revealed the altered enzyme to be inactive. Further scrutiny of sequence data and the crystal structures of two members of the PPi synthetase family implicated Lys321 in the proposed adenylation function of ThiI, and the critical nature of Lys321 has been demonstrated by site-directed mutagenesis and genetic screening. Our results, then, indicate that ThiI catalyzes the adenylation of a substrate at the expense of ATP, a narrowing of possible reactions that provides a strong new basis for deducing the early steps in the transfer of sulfur from cysteine to both thiamin and 4-thiouridine.  (+info)

Identification of the novobiocin biosynthetic gene cluster of Streptomyces spheroides NCIB 11891. (2/66)

The novobiocin biosynthetic gene cluster from Streptomyces spheroides NCIB 11891 was cloned by using homologous deoxynucleoside diphosphate (dNDP)-glucose 4,6-dehydratase gene fragments as probes. Double-stranded sequencing of 25.6 kb revealed the presence of 23 putative open reading frames (ORFs), including the gene for novobiocin resistance, gyrB(r), and at least 11 further ORFs to which a possible role in novobiocin biosynthesis could be assigned. An insertional inactivation experiment with a dNDP-glucose 4, 6-dehydratase fragment resulted in abolishment of novobiocin production, since biosynthesis of the deoxysugar moiety of novobiocin was blocked. Heterologous expression of a key enzyme of novobiocin biosynthesis, i.e., novobiocic acid synthetase, in Streptomyces lividans TK24 further confirmed the involvement of the analyzed genes in the biosynthesis of the antibiotic.  (+info)

Cloning, overexpression, and purification of novobiocic acid synthetase from Streptomyces spheroides NCIMB 11891. (3/66)

Novobiocic acid synthetase, a key enzyme in the biosynthesis of the antibiotic novobiocin, was cloned from the novobiocin producer Streptomyces spheroides NCIMB 11891. The enzyme is encoded by the gene novL, which codes for a protein of 527 amino acids with a calculated mass of 56,885 Da. The protein was overexpressed as a His(6) fusion protein in Escherichia coli and purified to apparent homogeneity by affinity chromatography and gel chromatography. The purified enzyme catalyzed the formation of an amide bond between 3-dimethylallyl-4-hydroxybenzoic acid (ring A of novobiocin) and 3-amino-4,7-dihydroxy-8-methyl coumarin (ring B of novobiocin) in an ATP-dependent reaction. NovL shows homology to the superfamily of adenylate-forming enzymes, and indeed the formation of an acyl adenylate from ring A and ATP was demonstrated by an ATP-PP(i) exchange assay. The purified enzyme exhibited both activation and transferase activity, i.e. it catalyzed both the activation of ring A as acyl adenylate and the subsequent transfer of the acyl group to the amino group of ring B. It is active as a monomer as determined by gel filtration chromatography. The reaction was specific for ATP as nucleotide triphosphate and dependent on the presence of Mg(2+) or Mn(2+). Apparent K(m) values for ring A and ring B were determined as 19 and 131 micrometer respectively. Of several analogues of ring A, only 3-geranyl-4-hydroxybenzoate and to a lesser extent 3-methyl-4-aminobenzoate were accepted as substrates.  (+info)

Characterization of recombinant glutathionylspermidine synthetase/amidase from Crithidia fasciculata. (4/66)

Trypanothione [N1,N8-bis(glutathionyl)spermidine] is a unique metabolite found only in trypanosomatids, where it subsumes many of the functions of GSH in other organisms. In Crithidia fasciculata, two distinct ATP-dependent ligases, glutathionylspermidine synthetase (GspS; EC 6.3.1.8) and trypanothione synthetase (TryS; EC 6.3.1.9), are involved in the synthesis of trypanothione from GSH and spermidine. Both enzymes have been cloned previously, but expression in Escherichia coli produced insoluble and inactive protein. Here we report on the successful expression of soluble (His)6-tagged C. fasciculata GspS in E. coli. Following purification using nickel-chelating affinity chromatography, the tag sequence was removed and the enzyme purified to homogeneity by anion-exchange chromatography. The kinetic parameters of the recombinant enzyme have been determined using a coupled enzyme assay and also by HPLC analysis of end-product formation. Under optimal conditions (0.1 M K+-Hepes, pH 7.3) GspS has synthetase activity with apparent K(m) values for GSH, spermidine and MgATP of 242, 59 and 114 microM respectively, and a k(cat) of 15.5 s(-1). Glutathionylspermidine is formed as end product and the enzyme lacks TryS activity. Like E. coli GspS, the recombinant enzyme also possesses amidase activity (EC 3.5.1.78), hydrolysing glutathionylspermidine to GSH and spermidine with a k(cat) of 0.38 s(-1) and a K(m) of 500 microM. GspS can also hydrolyse trypanothione at about 1.5% of the rate with glutathionylspermidine. A single amino acid mutation (Cys-79-->Ala) is shown to ablate the amidase activity without affecting the synthetase activity.  (+info)

A single enzyme catalyses formation of Trypanothione from glutathione and spermidine in Trypanosoma cruzi. (5/66)

Protozoa of the order Kinetoplastida differ from other organisms in their ability to conjugate glutathione (l-gamma-glutamyl-cysteinyl-glycine) and spermidine to form trypanothione [N(1),N(8)-bis(glutathionyl)spermidine], a metabolite involved in defense against chemical and oxidant stress and other biosynthetic functions. In Crithidia fasciculata, trypanothione is synthesized from GSH and spermidine via the intermediate glutathionylspermidine in two distinct ATP-dependent reactions catalyzed by glutathionylspermidine synthetase (GspS; EC ) and trypanothione synthetase (TryS; EC ), respectively. Here we have cloned a single copy gene (TcTryS) from Trypanosoma cruzi encoding a protein with 61% sequence identity with CfTryS but only 31% with CfGspS. Saccharomyces cerevisiae transformed with TcTryS were able to synthesize glutathionylspermidine and trypanothione, suggesting that this enzyme is able to catalyze both biosynthetic steps, unlike CfTryS. When cultures were supplemented with aminopropylcadaverine, yeast transformants contained glutathionylaminopropylcadaverine and homotrypanothione [N(1),N(9)-bis(glutathionyl)aminopropylcadaverine], metabolites that have been previously identified in T. cruzi, but not in C. fasciculata. Kinetic studies on recombinant TcTryS purified from Escherichia coli revealed that the enzyme displays high-substrate inhibition with glutathione (K(m) and K(i) of 0.57 and 1.2 mm, respectively, and k(cat) of 3.4 s(-1)), but obeys Michaelis-Menten kinetics with spermidine, aminopropylcadaverine, glutathionylspermidine, and MgATP as variable substrate. The recombinant enzyme possesses weak amidase activity and can hydrolyze trypanothione, homotrypanothione, or glutathionylspermidine to glutathione and the corresponding polyamine.  (+info)

Stable ammonia-specific NAD synthetase from Bacillus stearothermophilus: purification, characterization, gene cloning, and applications. (6/66)

Bacillus stearothermophilus H-804 isolated from a hot spring in Beppu, Japan, produced an ammonia-specific NAD synthetase (EC 6.3.1.5). The enzyme specifically used NH3 as an amide donor for the synthesis of NAD as it formed AMP and pyrophosphate from deamide-NAD and ATP. None of the l-amino acids tested, such as l-asparagine or l-glutamine, or other amino compounds such as urea, uric acid, or creatinine was used instead of NH3. Mg2+ was needed for the activity, and the maximum enzyme activity was obtained with 3 mM MgCl2. The molecular mass of the native enzyme was 50 kDa by gel filtration, and SDS-PAGE showed a single protein band at the molecular mass of 25 kDa. The optimum pH and temperature for the activity were from 9.0 to 10.0 and 60 degrees C, respectively. The enzyme was stable at a pH range of 7.5 to 9.0 and up to 60 degrees C. The Km for NH3, ATP, and deamide-NAD were 0.91, 0.052, and 0.028 mM, respectively. The gene encoding the enzyme consisted of an open reading frame of 738 bp and encoded a protein of 246 amino acid residues. The deduced amino acid sequence of the gene had about 32% homology to those of Escherichia coli and Bacillus subtilis NAD synthetases. We caused the NAD synthetase gene to be expressed in E. coli at a high level; the enzyme activity (per liter of medium) produced by the recombinant E. coli was 180-fold that of B. stearothermophilus H-804. The specific assay of ammonia and ATP (up to 25 microM) with this stable NAD synthetase was possible.  (+info)

Molecular identification of human glutamine- and ammonia-dependent NAD synthetases. Carbon-nitrogen hydrolase domain confers glutamine dependency. (7/66)

NAD synthetase catalyzes the final step in the biosynthesis of NAD. In the present study, we obtained cDNAs for two types of human NAD synthetase (referred as NADsyn1 and NADsyn2). Structural analysis revealed in both NADsyn1 and NADsyn2 a domain required for NAD synthesis from ammonia and in only NADsyn1 an additional carbon-nitrogen hydrolase domain shared with enzymes of the nitrilase family that cleave nitriles as well as amides to produce the corresponding acids and ammonia. Consistent with the domain structures, biochemical assays indicated (i) that both NADsyn1 and NADsyn2 have NAD synthetase activity, (ii) that NADsyn1 uses glutamine as well as ammonia as an amide donor, whereas NADsyn2 catalyzes only ammonia-dependent NAD synthesis, and (iii) that mutant NADsyn1 in which Cys-175 corresponding to the catalytic cysteine residue in nitrilases was replaced with Ser does not use glutamine. Kinetic studies suggested that glutamine and ammonia serve as physiological amide donors for NADsyn1 and NADsyn2, respectively. Both synthetases exerted catalytic activity in a multimeric form. In the mouse, NADsyn1 was seen to be abundantly expressed in the small intestine, liver, kidney, and testis but very weakly in the skeletal muscle and heart. In contrast, expression of NADsyn2 was observed in all tissues tested. Therefore, we conclude that humans have two types of NAD synthetase exhibiting different amide donor specificity and tissue distributions. The ammonia-dependent synthetase has not been found in eucaryotes until this study. Our results also indicate that the carbon-nitrogen hydrolase domain is the functional domain of NAD synthetase to make use of glutamine as an amide donor in NAD synthesis. Thus, glutamine-dependent NAD synthetase may be classified as a possible glutamine amidase in the nitrilase family. Our molecular identification of NAD synthetases may prove useful to learn more of mechanisms regulating cellular NAD metabolism.  (+info)

Eukaryotic NAD+ synthetase Qns1 contains an essential, obligate intramolecular thiol glutamine amidotransferase domain related to nitrilase. (8/66)

NAD+ is an essential co-enzyme for redox reactions and is consumed in lysine deacetylation and poly(ADP-ribosyl)ation. NAD+ synthetase catalyzes the final step in NAD+ synthesis in the well characterized de novo, salvage, and import pathways. It has been long known that eukaryotic NAD+ synthetases use glutamine to amidate nicotinic acid adenine dinucleotide while many purified prokaryotic NAD+ synthetases are ammonia-dependent. Earlier, we discovered that glutamine-dependent NAD+ synthetases contain N-terminal domains that are members of the nitrilase superfamily and hypothesized that these domains function as glutamine amidotransferases for the associated synthetases. Here we show yeast glutamine-dependent NAD+ synthetase Qns1 requires both the nitrilase-related active-site residues and the NAD+ synthetase active-site residues for function in vivo. Despite failure to complement the lethal phenotype of qns1 disruption, the former mutants retain ammonia-dependent NAD+ synthetase activity in vitro, whereas the latter mutants retain basal glutaminase activity. Moreover, the two classes of mutants fail to trans-complement despite forming a stable heteromultimer in vivo. These data indicate that the nitrilase-related domain in Qns1 is the fourth independently evolved glutamine amidotransferase domain to have been identified in nature and that glutamine-dependence is an obligate phenomenon involving intramolecular transfer of ammonia over a predicted distance of 46 A from one active site to another within Qns1 monomers.  (+info)

NAD+ synthase (EC 6.3.5.1) catalyzes the last step in the biosynthesis of nicotinamide adenine dinucleotide and is induced by stress factors such as heat shock and glucose limitation. The three-dimensional structure of NH3-dependent NAD+ synthetase from Bacillus subtilis, in its free form and in complex with ATP shows that the enzyme consists of a tight homodimer with alpha/beta subunit topology [(PUBMED:8895556)]. This domain is also found in guanosine 5-monophosphate (GMP) synthetase. GMP synthase catalyses the synthesis of GMP from XMP. The protein is a homodimer, but in some archaea it is a heterodimer composed of a glutamine amidotransferase subunit and a ATP pyrophosphatase subunit. In eucaryotes, bacteria, and some archaea the two catalytic units are encoded by a single gene, producing a two-domain-type GMP, with a GATase domain in the N-terminal half and a ATP-PPase domain in the C-terminal half. This entry represents the ATP pyrophosphatase domain. ...

Thirteen genomic regions showing strong geographical variation are listed in Table 1, and Supplementary Fig. 7 shows the way in which their allele frequencies vary geographically. The predominant pattern is variation along a NW/SE axis. The most likely cause for these marked geographical differences is natural selection, most plausibly in populations ancestral to those now in the UK. Variation due to selection has previously been implicated at LCT (lactase) and major histocompatibility complex (MHC), and within-UK differentiation at 4p14 has been found independently, but others seem to be new findings. All but three of the regions contain known genes. Aside from evolutionary interest, genes showing evidence of natural selection are particularly interesting for the biology of traits such as infectious diseases; possible targets for selection include NADSYN1 (NAD synthetase 1) at 11q13, which could have a role in prevention of pellagra, as well as TLR1 (toll-like receptor 1) at 4p14, for which a ...

The identified SNPs from four gene regions, collectively explain approximately 5% of the variance in circulating 25(OH)D. Methods: We investigated whether six polymorphisms in GC, CYP2R1, CYP24A1 and DHCR7/NADSYN1, genes previously shown to be associated with circulating 25(OH)D levels, were associated with CRC risk in 10,061 cases and 12,768 controls drawn from 13 studies included in the Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO) and Colon Cancer Family Registry (CCFR). We performed a meta-analysis of crude and multivariate-adjusted logistic regression models to calculate odds ratios and associated confidence intervals for SNPs individually, ...
