Carbon 13 NMR study of nonenzymatic reactions of pyridoxal 5'-phosphate with selected amino acids and of related reactions. (1/5406)

Carbon 13 nuclear magnetic resonance spectroscopy has been used to monitor the nonenzymatic reactions of pyridoxal 5'-phosphate with glycine, alanine, valine, serine, and with several other model compounds. Isotopically enriched amino acids were employed so that low concentrations could be utilized while still allowing relatively rapid acquisition of spectral data. The results for alanine and serine are particularly noteworthy in that alanine is deaminated to pyruvate and pyruvate is aminated to alanine, but contrary to the enzymatic reactions of various serine dehydratases wherein serine is converted to pyruvate, the nonenzymatic reaction utilizing serine results in hydroxypruvate rather than pyruvate formation. In the reverse reaction, hydroxypyruvate is aminated to serine but very inefficiently relative to the amination of pyruvate to alanine. The experimental results have been formulated into a proposed reaction mechanism for deamination of amino acids by pyridoxal-P.  (+info)

Biochemical and electrophysiological studies on the mechanism of action of PNU-151774E, a novel antiepileptic compound. (2/5406)

PNU-151774E [(S)-(+)-2-(4-(3-fluorobenzyloxy)benzylamino)propanamide methanesulfonate], a new anticonvulsant that displays a wide therapeutic window, has a potency comparable or superior to that of most classic anticonvulsants. PNU-151774E is chemically unrelated to current antiepileptics. In animal seizure models it possesses a broad spectrum of action. In the present study, the action mechanism of PNU-151774E has been investigated using electrophysiological and biochemical assays. Binding studies performed with rat brain membranes show that PNU-151774E has high affinity for binding site 2 of the sodium channel receptor, which is greater than that of phenytoin or lamotrigine (IC50, 8 microM versus 47 and 185 microM, respectively). PNU-151774E reduces sustained repetitive firing in a use-dependent manner without modifying the first action potential in hippocampal cultured neurons. In the same preparation PNU-151774E inhibits tetrodotoxin-sensitive fast sodium currents and high voltage-activated calcium currents under voltage-clamp conditions. These electrophysiological activities of PNU-151774E correlate with its ability to inhibit veratrine and KCl-induced glutamate release in rat hippocampal slices (IC50, 56.4 and 185.5 microM, respectively) and calcium inward currents in mouse cortical neurons. On the other hand, PNU-151774E does not affect whole-cell gamma-aminobutryic acid- and glutamate-induced currents in cultured mouse cortical neurons. These results suggest that PNU-151774E exerts its anticonvulsant activity, at least in part, through inhibition of sodium and calcium channels, stabilizing neuronal membrane excitability and inhibiting transmitter release. The possible relevance of these pharmacological properties to its antiepileptic potential is discussed.  (+info)

Role of glutamine in human carbohydrate metabolism in kidney and other tissues. (3/5406)

Glutamine is the most abundant amino acid in the human body and is involved in more metabolic processes than any other amino acid. Until recently, the understanding of many aspects of glutamine metabolism was based on animal and in vitro data. However, recent studies using isotopic and balance techniques have greatly advanced the understanding of glutamine metabolism in humans and its role in glucose metabolism in the kidney and other tissues. There is now evidence that in postabsorptive humans, glutamine is an important glucose precursor and makes a significant contribution to the addition of new carbon to the glucose carbon pool. The importance of alanine for gluconeogenesis, viewed in terms of the addition of new carbons, is less than previously assumed. It appears that glutamine is predominantly a renal gluconeogenic substrate, whereas alanine gluconeogenesis is essentially confined to the liver. As shown recently, renal gluconeogenesis contributes 20 to 25% to whole-body glucose production. Moreover, glutamine has been shown not only to stimulate net muscle glycogen storage but also to stimulate gluconeogenesis in normal humans. Finally, in humans with type II diabetes, conversion of glutamine to glucose is increased (more so than that of alanine). The available evidence on the hormonal regulation of glutamine gluconeogenesis in kidney and liver and its alterations under pathological conditions are discussed.  (+info)

Structural determinants of the eosinophil: chemotactic activity of the acidic tetrapeptides of eosinophil chemotactic factor of anaphylaxis. (4/5406)

The acidic tetrapeptides of ECF-A, Ala/Val-Gly-Ser-Glu, exhibit peak in vitro chemotactic activity for human eosinophils at concentrations of 3 X 10(-8) M to 10(-6) M, and rapidly deactivate eosinophils to homologous and other stimuli at concentrations as low as 10(-10) M. The analogue Leu-Gly-Ser-Glu reaches peak activity at 10(-8)M-10(-7)M, while Phe-Gly-Ser-Glu requires 10(-4)M to elicit a peak response. Although inversion of the order of glycine and serine does not alter the eosinophil chemotactic activity of the tetrapeptides, deletion of glycine increases by 10-fold the concentration required for peak chemotactic activity, indicating the critical nature of the spacing between NH2- and COOH-terminal residues. The substituent COOH-terminal tripeptide, which is only marginally chemotactic, irreversibly suppresses eosinophil chemotactic responsiveness at a concentration 10,000-fold higher than concentrations necessary for deactivation by the intact tetrapeptide. The high concentration of tripeptide required for this cell directed effect, which is assumed to be analogous to deactivation, is attributed to the absence of the NH2-terminal residue which would facilitate effective interaction with the eosinophil. A substituent NH2-terminal tripeptide and amides of the NH2-terminal amino acids, which are devoid of chemotactic and deactivating activities, reversibly inhibit the tetrapeptide stimulus in a dose-response fashion. The additional finding that the NH2-terminal tripeptide protects the eosinophil from deactivation by the intact tetrapeptide confirms that the competitive interaction is stimulus specific.  (+info)

Variants of ribonuclease inhibitor that resist oxidation. (5/5406)

Human ribonuclease inhibitor (hRI) is a cytosolic protein that protects cells from the adventitious invasion of pancreatic-type ribonucleases. hRI has 32 cysteine residues. The oxidation of these cysteine residues to form disulfide bonds is a rapid, cooperative process that inactivates hRI. The most proximal cysteine residues in native hRI are two pairs that are adjacent in sequence: Cys94 and Cys95, and Cys328 and Cys329. A cystine formed from such adjacent cysteine residues would likely contain a perturbing cis peptide bond within its eight-membered ring, which would disrupt the structure of hRI and could facilitate further oxidation. We find that replacing Cys328 and Cys329 with alanine residues has little effect on the affinity of hRI for bovine pancreatic ribonuclease A (RNase A), but increases its resistance to oxidation by 10- to 15-fold. Similar effects are observed for the single variants, C328A hRI and C329A hRI, suggesting that oxidation resistance arises from the inability to form a Cys328-Cys329 disulfide bond. Replacing Cys94 and Cys95 with alanine residues increases oxidation resistance to a lesser extent, and decreases the affinity of hRI for RNase A. The C328A, C329A, and C328A/C329A variants are likely to be more useful than wild-type hRI for inhibiting pancreatic-type ribonucleases in vitro and in vivo. We conclude that replacing adjacent cysteine residues can confer oxidation resistance in a protein.  (+info)

Multiplex sequence analysis demonstrates the competitive growth advantage of the A-to-G mutants of clarithromycin-resistant Helicobacter pylori. (6/5406)

Clarithromycin resistance in Helicobacter pylori is due to point mutation within the 23S rRNA. We examined the growth rates of different types of site-directed mutants and demonstrated quantitatively the competitive growth advantage of A-to-G mutants over other types of mutants by a multiplex sequencing assay. The results provide a rational explanation of why A-to-G mutants are predominantly observed among clarithromycin-resistant clinical isolates.  (+info)

The Escherichia coli Ada protein can interact with two distinct determinants in the sigma70 subunit of RNA polymerase according to promoter architecture: identification of the target of Ada activation at the alkA promoter. (7/5406)

The methylated form of the Ada protein (meAda) activates transcription from the Escherichia coli ada, aidB, and alkA promoters with different mechanisms. In this study we identify amino acid substitutions in region 4 of the RNA polymerase subunit sigma70 that affect Ada-activated transcription at alkA. Substitution to alanine of residues K593, K597, and R603 in sigma70 region 4 results in decreased Ada-dependent binding of RNA polymerase to the alkA promoter in vitro and impairs alkA transcription both in vivo and in vitro, suggesting that these residues define a determinant for meAda-sigma70 interaction. In a previous study (P. Landini, J. A. Bown, M. R. Volkert, and S. J. W. Busby, J. Biol. Chem. 273:13307-13312, 1998), we showed that a set of negatively charged amino acids in sigma70 region 4 is involved in meAda-sigma70 interaction at the ada and aidB promoters. However, the alanine substitutions of positively charged residues K593, K597, and R603 do not affect meAda-dependent transcription at ada and aidB. Unlike the sigma70 amino acids involved in the interaction with meAda at the ada and aidB promoters, K593, K597, and R603 are not conserved in sigmaS, an alternative sigma subunit of RNA polymerase mainly expressed during the stationary phase of growth. While meAda is able to promote transcription by the sigmaS form of RNA polymerase (EsigmaS) at ada and aidB, it fails to do so at alkA. We propose that meAda can activate transcription at different promoters by contacting distinct determinants in sigma70 region 4 in a manner dependent on the location of the Ada binding site.  (+info)

CPCCOEt, a noncompetitive metabotropic glutamate receptor 1 antagonist, inhibits receptor signaling without affecting glutamate binding. (8/5406)

Metabotropic glutamate receptors (mGluRs) are a family of G protein-coupled receptors characterized by a large, extracellular N-terminal domain comprising the glutamate-binding site. In the current study, we examined the pharmacological profile and site of action of the non-amino-acid antagonist 7-hydroxyiminocyclopropan[b]chromen-1a-carboxylic acid ethyl ester (CPCCOEt). CPCCOEt selectively inhibited glutamate-induced increases in intracellular calcium at human mGluR1b (hmGluR1b) with an apparent IC50 of 6.5 microM while having no agonist or antagonist activity at hmGluR2, -4a, -5a, -7b, and -8a up to 100 microM. Schild analysis indicated that CPCCOEt acts in a noncompetitive manner by decreasing the efficacy of glutamate-stimulated phosphoinositide hydrolysis without affecting the EC50 value or Hill coefficient of glutamate. Similarly, CPCCOEt did not displace [3H]glutamate binding to membranes prepared from mGluR1a-expressing cells. To elucidate the site of action, we systematically exchanged segments and single amino acids between hmGluR1b and the related subtype, hmGluR5a. Substitution of Thr815 and Ala818, located at the extracellular surface of transmembrane segment VII, with the homologous amino acids of hmGluR5a eliminated CPCCOEt inhibition of hmGluR1b. In contrast, introduction of Thr815 and Ala818 at the homologous positions of hmGluR5a conferred complete inhibition by CPCCOEt (IC50 = 6.6 microM), i.e., a gain of function. These data suggest that CPCCOEt represents a novel class of G protein-coupled receptor antagonists inhibiting receptor signaling without affecting ligand binding. We propose that the interaction of CPCCOEt with Thr815 and Ala818 of mGluR1 disrupts receptor activation by inhibiting an intramolecular interaction between the agonist-bound extracellular domain and the transmembrane domain.  (+info)

The effects of metabolic inhibitors and ouabain on alanine transport across rabbit ileum, in vitro, have been investigated. Net transport of alanine and Na across short-circuited segments of ileum is virtually abolished by cyanide, 2,4-dinitrophenol, iodoacetate, and ouabain. However, these inhibitors do not markedly depress alanine influx from the mucosal solution, across the brush border, into the intestinal epithelium, and they do not significantly affect the Na dependence of this entry process. The results of this investigation indicate that: (a) the Na dependence of alanine influx does not reflect a mechanism in which the sole function of Na is to link metabolic energy directly to the influx process; and (b) the inhibition of net alanine transport across intestine is, in part, the result of an increased rate coefficient for alanine efflux out of the cell across the brush border. Although these findings do not exclude a direct link between metabolic energy and alanine efflux, the increased ...
1. The metabolism of glutamine and alanine in the lung was studied in rats made septic by a caecal ligation and puncture technique.. 2. The blood glucose concentration was not significantly different in septic rats, but blood pyruvate, lactate, glutamine and alanine concentrations were markedly increased as compared with sham-operated rats. Conversely, blood ketone body and plasma cholesterol concentrations were significantly decreased in septic rats. Both plasma insulin and plasma glucagon concentrations were markedly elevated in response to sepsis. Sepsis resulted in a negative nitrogen balance.. 3. Sepsis increased the rates of production of glutamine (52.5%, P ,0.001), alanine (38.9%, P ,0.001) and glutamate (48.6%, P ,0.001) by lung slices incubated in vitro.. 4. Sepsis increased lung blood flow by 27.6% (P ,0.05). Blood flow and arteriovenous concentration difference measurement across the lung of septic rats showed an increase in the net exchange rates of glutamine (142.5%, P ,0.001), ...
The focus of this study was the pathways for β-alanine production in Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis. The major pathway for β-alanine production is the decarboxylation of L-aspartate by L-aspartate-α-decarboxylase (PanD). This enzyme is not essential for the survival for Mtb which implies that an alternative pathway for β-alanine production must exist. We postulated that such a secondary pathway may be based on the oxidation of various polyamines by a polyamine oxidase to give the β-alanine precursor 3-aminopropanal, and therefore set out to find data in support of this hypothesis. Based on sequence homology to the FAD-dependent Saccharomyces cerevisiae polyamine oxidase Fms1, Mtb AofH was identified as a likely candidate. The soluble expression and purification of AofH proved troublesome and lead to the investigation of various techniques to increase protein yield. These methods include fusion to various tags, coexpression with the protein chaperones, ...

TY - JOUR. T1 - Characterization of novel yeast Rad6 (UBC2) ubiquitin-conjugating enzyme mutants constructed by charge-to-alanine scanning mutagenesis. AU - McDonough, Michele M. AU - Sagan, P. AU - Gonda, D. PY - 1995. Y1 - 1995. N2 - Ubiquitination of intracellular proteins by the yeast RAD6 (UBC2) ubiquitin-conjugating (E2) enzyme is required for cellular processes as diverse as DNA repair, selective proteolysis, and normal growth. For most RAD6-dependent functions, the relevant in vivo targets, as well as the mechanisms and cofactors that govern RAD6 substrate selectivity, are unknown. We have explored the utility of charge-to-alanine scanning mutagenesis to generate novel RAD6 mutants that are enzymatically competent with respect to unfacilitated (E3-independent) ubiquitination but that are nevertheless severely handicapped with respect to several in vivo functions. Five of the nine mutants we generated show defects in their in vivo functions, but almost all of the most severely affected ...
TY - JOUR. T1 - L-alanine absorption in human intestinal Caco-2 cells driven by the proton electrochemical gradient. AU - Thwaites, D T. AU - McEwan, Gordon T.A.. AU - Brown, C D. AU - Hirst, B H. AU - Simmons, N L. PY - 1994/6. Y1 - 1994/6. N2 - In human Caco-2 intestinal epithelial layers, L-alanine absorption can be energized by a proton gradient across the brush-border membrane. Acidification of the apical medium, even in Na(+)-free media, is associated with a saturable net transepithelial absorption of L-alanine. L-Alanine transport causes cytosolic acidification consistent with proton/amino acid symport. L-Alanine transport in Na(+)-free media is rheogenic, stimulating an inward short-circuit current in voltage-clamped epithelial monolayers. By measurement of rapid L-alanine influx across the apical membrane, L-alanine-stimulated inward short-circuit current and intracellular acidification in the same cell batch, we estimate L-alanine/proton stoichiometry to be 1:0.62 +/- 0.25 (SD) ...
These data demonstrate that chronic hyperglucagonemia, when accompanied by increases in gluconeogenic precursor availability and adequate circulating concentrations of NEFA, can contribute to the infection-induced increase in glucose production and gluconeogenesis. These data confirm that even in an animal reliant predominantly on gluconeogenesis, combined increases in lactate and alanine uptake by the liver are unable to increase hepatic glucose output. If the substrate-induced suppression of NEFAs is prevented and/or NEFAs are increased, increases in gluconeogenic precursor supply can support an increase in hepatic glucose production.. Chronic hyperglucagonemia markedly enhanced the importance of the liver in disposal of the exogenous alanine. As expected, the uptake of alanine by the liver increased in parallel with the rise in alanine levels. This is reflected in the constancy of net fractional hepatic alanine extraction in the face of increases in blood alanine concentration (6). ...
Unidirectional influxes of L-alanine and Na from the mucosal solution into the epithelium of in vitro rabbit ileum have been determined. In the presence of 140 mM Na, alanine influx is approximately 2.2 µmoles/hr cm2, but is inhibited if the NaCl in the mucosal solution is replaced by choline Cl, Tris-Cl, mannitol, LiCl, or KCl. Although alanine influx is strongly dependent upon Na in the mucosal solution, it is uninfluenced by marked reduction of intracellular Na pools. In addition, alanine influx is unaffected by intracellular alanine concentration. Na influx is markedly inhibited by the presence of Li. Evidence is presented that Na transport across the mucosal border cannot be attributed to simple diffusion even though the net flux across this surface is in the direction of the electrochemical potential difference.. ...
Although the stimulatory effect of glucagon on gluconeogenesis has been well demonstrated in certain systems in vitro, this effect has never been established in man. The present study was undertaken, therefore, to determine whether glucagon could stimulate gluconeogenesis from alanine in normal fasting man. Glucagon might stimulate this process by increasing the hepatic alanine uptake and/or by shunting the extracted alanine within the liver into the gluconeogenic pathway. In order to be able to examine these two aspects of gluconeogenesis, we combined the hepatic veinbrachial artery catheterization technic with an isotopic infusion of alanine-14C. Alanine-14C specific activity was measured in whole blood and plasma by use of a rapid chromatographic technic. Since plasma contributed 93 per cent of the alanine extracted by the splanchnic bed with a specific activity three times that of the red blood cells, plasma alanine specific activity was used to study the conversion of alanine to glucose. A ...
Alanine dipeptide is one of the simplest molecules that exhibits some important features common to larger biomolecules. In particular, it has more than one long-lived conformation, which we will identify in this exercise by mapping out its potential energy surface. The conformations of alanine dipeptide are characterized by the dihedral angles of the backbone. Below, we color carbons in green, hydrogens in white, oxygen in red and nitrogen in blue, i.e. the torsional angle $\phi$ is C-N-C-C, while $\psi$ is N-C-C-N along the backbone. ...

Alanine dipeptide is often studied in theoretical work because it is among the simplest systems to exhibit some of the important features common to biomolecules. It has more than one long-lived conformational state. The relevant angles are the dihedral angles of the backbone, commonly called Φ and Ψ (see figure). In the following scheme, light blue atoms are carbons, white ones are hydrogens, red are oxygens, and blue are nitrogens. So the torsional angle Φ is C-N-C-C and Ψ is N-C-C-N along the backbone ...

This reaction, and by extension the glycine cleavage system, is required for photorespiration in C3 plants. The glycine cleavage system takes glycine, which is created from an unwanted byproduct of the Calvin cycle, and converts it to serine which can reenter the cycle. The ammonia generated by the glycine cleavage system, is assimilated by the Glutamine synthetase-Glutamine oxoglutarate aminotransferase cycle but costs the cell one ATP and one NADPH. The upside is that one CO2 is produced for every two O2 that are mistakenly taken up by the cell, generating some value in an otherwise energy depleting cycle. Together the proteins involved in these reactions comprise about half the proteins in mitochondria from spinach and pea leaves.[3] The glycine cleavage system is constantly present in the leaves of plants, but in small amounts until they are exposed to light. During peak photosynthesis, the concentration of the glycine cleavage system increases ten-fold.[7] In the anaerobic bacteria, ...

The mitochondrial creatine kinase (CKm) is present in the mitochondrial intermembrane space, where it regenerates phosphocreatine (PCr) from mitochondrially generated ATP and creatine (Cr) imported from the cytosol. Apart from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK (present in non-muscle tissues) and sarcomeric mtCK (present in sarcomeric muscle), there are three cytosolic CK isoforms present in the cytosol, depending on the tissue. Whereas MM-CK is expressed in sarcomeric muscle, that is, skeletal and cardiac muscle, MB-CK is expressed in cardiac muscle, and BB-CK is expressed in smooth muscle and in most non-muscle tissues. Mitochondrial mtCK and cytosolic CK are connected in a so-called PCr/Cr-shuttle or circuit.

... crosses the protective blood-brain barrier, whereas dopamine itself cannot. Thus, L-DOPA is used to increase dopamine concentrations in the treatment of Parkinson's disease and dopamine-responsive dystonia. This treatment was made practical and proven clinically by George Cotzias and his coworkers, for which they won the 1969 Lasker Prize.[4][5] Once L-DOPA has entered the central nervous system, it is converted into dopamine by the enzyme aromatic L-amino acid decarboxylase, also known as DOPA decarboxylase. Pyridoxal phosphate (vitamin B6) is a required cofactor in this reaction, and may occasionally be administered along with L-DOPA, usually in the form of pyridoxine.. Besides the central nervous system, L-DOPA is also converted into dopamine from within the peripheral nervous system. Excessive peripheral dopamine signaling causes many of the adverse side effects seen with sole L-DOPA administration. To bypass these effects, it is standard clinical practice to coadminister (with ...
... is an oxidase that is the rate-limiting enzyme for controlling the production of melanin. The enzyme is mainly involved in two distinct reactions of melanin synthesis otherwise known as the Raper Mason pathway. Firstly, the hydroxylation of a monophenol and secondly, the conversion of an o-diphenol to the corresponding o-quinone. o-Quinone undergoes several reactions to eventually form melanin.[5] Tyrosinase is a copper-containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation. It is found inside melanosomes which are synthesized in the skin melanocytes. In humans, the tyrosinase enzyme is encoded by the TYR gene.[6] ...

... poisoning is the most common type of fatal air poisoning in many countries.[28] Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin.[29] A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.[30]. The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, ...

... is a peptide of nine amino acids (a nonapeptide) in the sequence cysteine-tyrosine-isoleucine-glutamine-asparagine-cysteine-proline-leucine-glycine-amide (Cys - Tyr - Ile - Gln - Asn - Cys - Pro - Leu - Gly - NH2, or CYIQNCPLG-NH2); its C-terminus has been converted to a primary amide and a disulfide bridge joins the cysteine moieties.[116] Oxytocin has a molecular mass of 1007 Da, and one international unit (IU) of oxytocin is the equivalent of about 2 μg of pure peptide. While the structure of oxytocin is highly conserved in placental mammals, a novel structure of oxytocin was recently reported in marmosets, tamarins, and other new world primates. Genomic sequencing of the gene for oxytocin revealed a single in-frame mutation (thymine for cytosine) which results in a single amino acid substitution at the 8-position (proline for leucine).[117] Since this original Lee et al. paper, two other laboratories have confirmed Pro8-OT and documented additional oxytocin structural variants in ...
