Reduction of adenosine-5'-phosphosulfate instead of 3'-phosphoadenosine-5'-phosphosulfate in cysteine biosynthesis by Rhizobium meliloti and other members of the family Rhizobiaceae. (1/37)

We have cloned and sequenced three genes from Rhizobium meliloti (Sinorhizobium meliloti) that are involved in sulfate activation for cysteine biosynthesis. Two of the genes display homology to the Escherichia coli cysDN genes, which code for an ATP sulfurylase (EC 2.7.7.4). The third gene has homology to the E. coli cysH gene, a 3'-phosphoadenosine-5'-phosphosulfate (PAPS) reductase (EC 1.8.99.4), but has greater homology to a set of genes found in Arabidopsis thaliana that encode an adenosine-5'-phosphosulfate (APS) reductase. In order to determine the specificity of the R. meliloti reductase, the R. meliloti cysH homolog was histidine tagged and purified, and its specificity was assayed in vitro. Like the A. thaliana reductases, the histidine-tagged R. meliloti cysH gene product appears to favor APS over PAPS as a substrate, with a Km for APS of 3 to 4 microM but a Km for PAPS of >100 microM. In order to determine whether this preference for APS is unique to R. meliloti among members of the family Rhizobiaceae or is more widespread, cell extracts from R. leguminosarum, Rhizobium sp. strain NGR234, Rhizobium fredii (Sinorhizobium fredii), and Agrobacterium tumefaciens were assayed for APS or PAPS reductase activity. Cell extracts from all four species also preferentially reduce APS over PAPS.  (+info)

Identification of a new class of 5'-adenylylsulfate (APS) reductases from sulfate-assimilating bacteria. (2/37)

A gene was cloned from Burkholderia cepacia DBO1 that is homologous with Escherichia coli cysH encoding 3'-phosphoadenylylsulfate (PAPS) reductase. The B. cepacia gene is the most recent addition to a growing list of cysH homologs from a diverse group of sulfate-assimilating bacteria whose products show greater homology to plant 5'-adenylylsulfate (APS) reductase than they do to E. coli CysH. The evidence reported here shows that the cysH from one of the species, Pseudomonas aeruginosa, encodes APS reductase. It is able to complement an E. coli cysH mutant and a cysC mutant, indicating that the enzyme is able to bypass PAPS, synthesized by the cysC product. Insertional knockout mutation of P. aeruginosa cysH produced cysteine auxotrophy, indicating its role in sulfate assimilation. Purified P. aeruginosa CysH expressed as a His-tagged recombinant protein is able to reduce APS, but not PAPS. The enzyme has a specific activity of 5.8 micromol. min(-1). mg of protein(-1) at pH 8.5 and 30 degrees C with thioredoxin supplied as an electron donor. APS reductase activity was detected in several bacterial species from which the novel type of cysH has been cloned, indicating that this enzyme may be widespread. Although an APS reductase from dissimilatory sulfate-reducing bacteria is known, it shows no structural or sequence homology with the assimilatory-type APS reductase reported here. The results suggest that the dissimilatory and assimilatory APS reductases evolved convergently.  (+info)

Effects of AMP derivatives on cyclic AMP levels in NG108-15 cells. (3/37)

1. In NG108-15 neuroblastomaxglioma hybrid cells, ATP stimulates intracellular cyclic AMP formation, which is inhibited by both adenosine (P(1)) and P2 receptor antagonists. In the present study, we examined the effects of several AMP derivatives in NG108-15 cells and mouse neuroblastoma N18TG-2 cells. 2. Adenosine 2'-monophosphate (A2P), adenosine 3'-monophosphate (A3P) and adenosine 5'-phosphosulphate (A5PS) increased cyclic AMP levels with similar concentration-dependencies in NG108-15 cells. 3. Increases in cyclic AMP by AMP derivatives were inhibited by the P2 receptor antagonist PPADS, but not by suramin. Effects of AMP derivatives were also inhibited by P(1) receptor antagonists ZM241385, XAC, DPCPX and partially by alloxazine. The ecto-nucleotidase inhibitor alpha, beta-methyleneADP was without effect. 4. In contrast, AMP derivatives did not change cyclic AMP levels in N18TG-2 cells. Accumulation of cyclic AMP in N18TG-2 cells was stimulated by adenosine A(2) receptor agonists CGS21680 and NECA, but not by ATP or beta, gamma-methyleneATP, agonists for cyclic AMP production in NG108-15 cells. 5. Reverse transcription-coupled polymerase chain reaction (RT - PCR) analyses revealed that N18TG-2 cells express both A(2A) and A(2B) receptors, while NG108-15 cells express mainly A(2A) receptors. 6. AMP derivatives did not affect the P2X and P2Y receptors expressed in NG108-15 cells. 7. These results suggest that A2P, A3P and A5PS act as agonists for cyclic AMP production and that these compounds are valuable tools for determinating the mechanism of ATP-stimulated cyclic AMP response in NG108-15 cells.  (+info)

Sulfate assimilation in higher plants characterization of a stable intermediate in the adenosine 5'-phosphosulfate reductase reaction. (4/37)

The enzyme catalysing the reduction of adenosine 5'-phosphosulfate (AdoPS) to sulfite in higher plants, AdoPS reductase, is considered to be the key enzyme of assimilatory sulfate reduction. In order to address its reaction mechanism, the APR2 isoform of this enzyme from Arabidopsis thaliana was overexpressed in Escherichia coli and purified to homogeneity. Incubation of the enzyme with [35S]AdoPS at 4 degrees C resulted in radioactive labelling of the protein. Analysis of APR2 tryptic peptides revealed 35SO2-3 bound to Cys248, the only Cys conserved between AdoPS and prokaryotic phosphoadenosine 5'-phosphosulfate reductases. Consistent with this result, radioactivity could be released from the protein by incubation with thiols, inorganic sulfide and sulfite. The intermediate remained stable, however, after incubation with sulfate, oxidized glutathione or AdoPS. Because truncated APR2, missing the thioredoxin-like C-terminal part, could be labelled even at 37 degrees C, and because this intermediate was more stable than the complete protein, we conclude that the thioredoxin-like domain was required to release the bound SO2-3 from the intermediate. Taken together, these results demonstrate for the first time the binding of 35SO2-3 from [35S]AdoPS to AdoPS reductase and its subsequent release, and thus contribute to our understanding of the molecular mechanism of AdoPS reduction in plants.  (+info)

Crystal structure of ATP sulfurylase from Saccharomyces cerevisiae, a key enzyme in sulfate activation. (5/37)

ATP sulfurylases (ATPSs) are ubiquitous enzymes that catalyse the primary step of intracellular sulfate activation: the reaction of inorganic sulfate with ATP to form adenosine-5'-phosphosulfate (APS) and pyrophosphate (PPi). With the crystal structure of ATPS from the yeast Saccharomyces cerevisiae, we have solved the first structure of a member of the ATP sulfurylase family. We have analysed the crystal structure of the native enzyme at 1.95 Angstroms resolution using multiple isomorphous replacement (MIR) and, subsequently, the ternary enzyme product complex with APS and PPi bound to the active site. The enzyme consists of six identical subunits arranged in two stacked rings in a D:3 symmetric assembly. Nucleotide binding causes significant conformational changes, which lead to a rigid body structural displacement of domains III and IV of the ATPS monomer. Despite having similar folds and active site design, examination of the active site of ATPS and comparison with known structures of related nucleotidylyl transferases reveal a novel ATP binding mode that is peculiar to ATP sulfurylases.  (+info)

Identification of yacE (coaE) as the structural gene for dephosphocoenzyme A kinase in Escherichia coli K-12. (6/37)

Dephosphocoenzyme A (dephospho-CoA) kinase catalyzes the final step in coenzyme A biosynthesis, the phosphorylation of the 3'-hydroxy group of the ribose sugar moiety. Wild-type dephospho-CoA kinase from Corynebacterium ammoniagenes was purified to homogeneity and subjected to N-terminal sequence analysis. A BLAST search identified a gene from Escherichia coli previously designated yacE encoding a highly homologous protein. Amplification of the gene and overexpression yielded recombinant dephospho-CoA kinase as a 22.6-kDa monomer. Enzyme assay and nuclear magnetic resonance analyses of the product demonstrated that the recombinant enzyme is indeed dephospho-CoA kinase. The activities with adenosine, AMP, and adenosine phosphosulfate were 4 to 8% of the activity with dephospho-CoA. Homologues of the E. coli dephospho-CoA kinase were identified in a diverse range of organisms.  (+info)

Assay of adenosine 3'-phosphate 5'-sulphatophosphate in hepatic tissues. (7/37)

A fluorimetric assay, based on the ability of boiled hepatic extracts to support the sulphO-conjugation of harmol, was used to demonstrate and quantify PAdoPS (adenosine 3'-phosphate 5'-sulphatophosphate) present in liver. A stoicheiometric relationship was established between the sulphate conjugate formed and the 'active sulphate' utilized. Guinea-pig, rat, mouse and rabbit livers contain 3.3, 2.9, 0.8 and 0.5 mumol of PAdoPS/100 G wet wt. respectively.  (+info)

The presence of an iron-sulfur cluster in adenosine 5'-phosphosulfate reductase separates organisms utilizing adenosine 5'-phosphosulfate and phosphoadenosine 5'-phosphosulfate for sulfate assimilation. (8/37)

It was generally accepted that plants, algae, and phototrophic bacteria use adenosine 5'-phosphosulfate (APS) for assimilatory sulfate reduction, whereas bacteria and fungi use phosphoadenosine 5'-phosphosulfate (PAPS). The corresponding enzymes, APS and PAPS reductase, share 25-30% identical amino acids. Phylogenetic analysis of APS and PAPS reductase amino acid sequences from different organisms, which were retrieved from the GenBank(TM), revealed two clusters. The first cluster comprised known PAPS reductases from enteric bacteria, cyanobacteria, and yeast. On the other hand, plant APS reductase sequences were clustered together with many bacterial ones, including those from Pseudomonas and Rhizobium. The gene for APS reductase cloned from the APS-reducing cyanobacterium Plectonema also clustered together with the plant sequences, confirming that the two classes of sequences represent PAPS and APS reductases, respectively. Compared with the PAPS reductase, all sequences of the APS reductase cluster contained two additional cysteine pairs homologous to the cysteine residues involved in binding an iron-sulfur cluster in plants. Mossbauer analysis revealed that the recombinant APS reductase from Pseudomonas aeruginosa contains a [4Fe-4S] cluster with the same characteristics as the plant enzyme. We conclude, therefore, that the presence of an iron-sulfur cluster determines the APS specificity of the sulfate-reducing enzymes and thus separates the APS- and PAPS-dependent assimilatory sulfate reduction pathways.  (+info)

Induction of neural differentiation in cultures of undetermined presumptive epidermis from three amphibian species was achieved by the addition of 1 millimolar dibutyryl adenosine 3,5-monophosphate, 8-bromadenosine 3,5-monophosphate, or adenosine C,E-monophosphate together with theophylline. Adenosine 5-monophosphate, adenosine 2,3-monophosphate, dibutyryl guanosine 3,5-monophosphate, and butyrate at 1 millimolar are ineffective. These results suggest that the action of the primary inductor or inductors may be mediated via adenosine 3,5-monophosphate. ...

Plants need to strike a fine balance between the production, transport, and degradation of stress signals in order to optimize growth in fluctuating environmental conditions. The signal 3′-phosphoadenosine 5′-phosphate (PAP) accumulates during drought and light stress and induces stress-responsive gene expression (Estavillo et al., 2011). Sulfur transfer from 3′-phosphoadenosine 5′-phosphosulfate (PAPS) to acceptor compounds in the cytosol results in the release of PAP. PAP is then degraded by the enzyme SAL1 in plastids and mitochondria into AMP and inorganic phosphate. SAL1 tightly controls PAP levels, as constitutively elevated PAP levels markedly affect growth and development (Estavillo et al., 2011). However, insights into how this signaling molecule moves between different cellular compartments, and the specific implications of subcellular concentrations, have been elusive. Ashykhmina et al. (2019) expand on the discovery of the plastid-specific PAPS transporter PAPST1 ...

The sulphate activation and tyrosyl-protein sulphotransferase systems in normal 3Y1 rat embryo fibroblasts and the same cells transformed by Schmidt Ruppin subgroup-A-Rous sarcoma virus (SRA-3Y1) were examined. Employing metabolic [35S]sulphate-labelling followed by PEI (polyethyleneimine)-cellulose thin-layer chromatography of the labelled cell lysates, it was found that the steady-state level of active sulphate, adenosine 3′-phosphate 5′-phosphosulphate, was drastically lower in SRA-3Y1 cells compared with their normal counterparts. When the sulphate activating enzymes were tested, it appeared that the activities in 3Y1 homogenates were 2-2.5 times greater than those in SRA-3Y1 homogenates. An endogenous sulphation assay for tyrosyl-protein sulphotransferase revealed that activities in 3Y1 and SRA-3Y1 homogenates were comparable. Nearly identical patterns were observed with both sets of cells when [35S]sulphated proteins generated in the endogenous assay were separated by two-dimensional ...
Horses of extreme and opposite morphological types:(a) Rapid Heavy Draft (brachymorphic type or heavy) and (b) Italian Trotter (dolichomorphic type or light).
MicroRNAs play a key role in the control of plant development and response to adverse environmental conditions. For example, microRNA395 (miR395), which targets three out of four isoforms of ATP sulfurylase, the first enzyme of sulfate assimilation, as well as a low-affinity sulfate transporter, SULTR2;1, is strongly induced by sulfate deficiency. However, other components of sulfate assimilation are induced by sulfate starvation, so that the role of miR395 is counterintuitive. Here, we describe the regulation of miR395 and its targets by sulfate starvation. We show that miR395 is important for the increased translocation of sulfate to the shoots during sulfate starvation. MiR395 together with the SULFUR LIMITATION 1 transcription factor maintain optimal levels of ATP sulfurylase transcripts to enable increased flux through the sulfate assimilation pathway in sulfate-deficient plants. Reduced expression of ATP sulfurylase (ATPS) alone affects both sulfate translocation and flux, but SULTR2;1 is ...

Achondrogenesis is a number of disorders that are the most severe form of congenital chondrodysplasia (malformation of bones and cartilage). These conditions are characterized by a small body, short limbs, and other skeletal abnormalities. As a result of their serious health problems, infants with achondrogenesis are usually born prematurely, are stillborn, or die shortly after birth from respiratory failure. Some infants, however, have lived for a while with intensive medical support.. Researchers have described at least three forms of achondrogenesis, designated as Achondrogenesis type 1A, achondrogenesis type 1B and achondrogenesis type 2. These types are distinguished by their signs and symptoms, inheritance pattern, and genetic cause. Other types of achondrogenesis may exist, but they have not been characterized or their cause is unknown.. Achondrogenesis type 1A is caused by a defect in the microtubules of the Golgi apparatus. In mice, a nonsense mutation in the thyroid hormone receptor ...

Achondrogenesis is a severe skeletal dysplasia that is invariably lethal before or after birth. Achondrogenesis type IA (ACG1A; MIM 200600) and IB (ACG1B; MIM 600972) are autosomal recessive disorders caused by mutations in the TRIP11 and SLC26A2 genes, respectively. Achondrogenesis type II (ACG2; MIM 200610) is an autosomal dominant disorder caused by mutations in the COL2A1 gene. All types are clinically overlapping and are mainly characterized by short-limbed dwarfism, short ribs, small chest, absent or minimally ossified vertebral bodies, and hydrops fetalis.. Copy number variation (CNV) analysis of the Achondrogenesis genes is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes.

Achondrogenesis, type IB (ACG1B; MIM 600972) is a lethal condition caused by the diastrophic dysplasia sulfate transporter gene mutations (DTDST/SLC26A2). Affected fetuses are usually in breech position and appear hydropic. The limbs and the trunk are shortened. In contrast to the findings in achondrogenesis, type II (ACG2; MIM 200610), the head is of a normal or near normal size and the fingers and toes are short. The feet and toes are rotated inward, a finding shared with diastrophic dysplasia (DTD; MIM 222600), another disorder caused by DTDST mutations.. Read less ...

LOL. Again the other thread was more about getting boys snipped than men. A few people pointed out that there children who were not snipped had had really bad health problems, and snipping seemed to fix this. Others mentioned that it slowed the spread of HPV Human pap virus. I was doing some research to confirm this and came across the HIV news. Since its a pretty deadly disease and this is something that men can do to cut their risk by 50% if they are not using condoms, and even if they are, just cut down the risk that much further ...

Adenylylsulphate (adenosine-5′-phosphosulphate, APS) reductase from the extremely thermophilic sulphate-reducing archaeon Archaeoglobus fulgidus is an iron-sulphur flavoprotein containing one non-covalently bound flavin group, eight non-haem iron and six labile sulphide atoms per molecule. Re-evaluation of the enzyme structure revealed the presence of two different subunits with molecular masses of 80 and 18.5 kDa. The subunits are arranged in an α2β subunit structure. We have cloned and sequenced a 2.7 kb segment of DNA containing the genes for the α and β subunits, which we designate aprA and aprB, respectively. The two genes are separated by 17 bp and localized in the order aprBA. While a putative promoter could not be identified in the vicinity of aprBA a probable termination signal was found just downstream of the translation stop codon of aprA. The codon usage for aprBA shows strong preferences for G and C in the third codon position. aprA encodes a 73.3 kDa polypeptide, which shows
glycolithocholate sulfate = N-(3α-sulfooxy-5β-cholan-24-oyl)glycine. Other name(s): BAST I; bile acid:3-phosphoadenosine-5-phosphosulfate sulfotransferase; bile salt:3phosphoadenosine-5-phosphosulfate:sulfotransferase; bile acid sulfotransferase I; glycolithocholate sulfotransferase. Systematic name: 3-phosphoadenylyl-sulfate:glycolithocholate sulfotransferase. Comments: The formation of sulfate esters of bile acids is an essential step in the prevention of toxicity by monohydroxy bile acids in many species [3]. This enzyme is both a bile salt and a 3-hydroxysteroid sulfotransferase. In addition to the 5β-bile acid glycolithocholate, deoxycholate, 3β-hydroxy-5-cholenoate and dehydroepiandrosterone (3β-hydroxyandrost-5-en-17-one) also act as substrates [see also EC 2.8.2.2 (alcohol sulfotransferase) and EC 2.8.2.34 (glycochenodeoxycholate sulfotransferase)].

2 detailed and in-depth reviews for Chaind Reaction: ----Introduction---- APS is one of my favorite brands. I have tried lots of aminos with different qualities and effectiveness. I dont think they are a necessity but they are nice to have in my opinion and this is probably the best one Ive had. ----Ingredient Profile---- 2 scoops (12g) The ratio
Sulfation or sulfurylation (not to be confused with sulfonation) in biochemistry is the enzyme-catalyzed conjugation of a sulfo group (not a sulfate or sulfuryl group) to another molecule. This biotransformation involves a sulfotransferase enzyme catalyzing the transfer of a sulfo group from a donor cosubstrate, usually 3-phosphoadenosine-5-phosphosulfate (PAPS), to a substrate molecules hydroxyl or amine. Sulfation is involved in a variety of biological processes, including detoxification, hormone regulation, molecular recognition, cell signaling, and viral entry into cells. It is among the reactions in phase II drug metabolism, frequently effective in rendering a xenobiotic less active from a pharmacological and toxicological standpoint, but sometimes playing a role in the activation of xenobiotics (e.g. aromatic amines, methyl-substituted polycyclic aromatic hydrocarbons). Another example of biological sulfation is in the synthesis of sulfonated glycosaminoglycans, such as heparin, heparan ...

Y1 - 1980/4/11. N2 - Phenolsulphotransferase (EC 2.8.2.1) (PST) is an important catecholamine and drug metabolizing enzyme. Optimal conditions have been determined for the accurate measurement of PST activity in the human platelet, human renal cortex, and human jejunum with a radiochemical microassay. 3-Methoxy-4-hydroxyphenylglycol (MHPG) and 35S-3-phosphoadenosine-5-phosphosulfate (35S-PAPS) were the substrates for the reaction. The apparent Michaelis-Menten (Km) values for MHPG with platelet, renal cortex, and jejunum were 1.09, 0.46 and 1.16 mmol/l, respectively. Apparent Km values for PAPS in the same tissues were 0.14, 0.13 and 0.21 μmol/l. The pH optimum of the reaction in all three tissues was approximately 6.2-6.8 with three different buffer systems. The coefficients of variation for the assay of ...

The adrenal steroid dehydroepiandrosterone (DHEA) and its sulphate ester, DHEAS are the most abundant circulating steroid hormones in humans. Uncongugated DHEA predominately exerts its effects via its downstream conversion to active sex steroids in peripheral target tissues. In contrast the conversion of DHEAS to androgens first requires cleavage of the sulfate group, catalysed by the microsomal enzyme steroid sulfatase (STS). Conversely, DHEA is converted to inactive DHEAS by the activity of the cytosolic enzyme DHEA sulphotransferase (SULT2A1). However, in addition, evidence is growing that DHEA and DHEAS can have specific, direct effects. In this thesis, I have demonstrated that abrogation of DHEA metabolism can result in the manifestation of pathophysiological conditions. SULT2A1 requires 3-phosphoadenosine-5-phosphosulfate (PAPS) for catalytic activity. I have identified compound heterozygous mutations in the gene encoding human PAPS synthase 2 (PAPSS2) in a girl with androgen excess and ...

  • Sulfate is activated at the expense of two ATP equivalents through the activity of sulfate adenylyltransferase ( equation 1 ), producing adenosine phosphosulfate (APS), which increases the redox potential of the APS/HSO 3 − couple to −60 mV ( 5 , 6 ), allowing reduction by electrons from H 2 or organic electron donors.
