Hemoglobin Providence. A human hemoglobin variant occurring in two forms in vivo. (1/1939)

Hemoglobin Providence Asn and Hemoglobin Providence Asp are two abnormal hemoglobins which apparently arise from a single genetic change that substitutes asparagine for lysine at position 82 (EF6) in the beta chain of human hemoglobin. The second form appears to be thr result of a partial in vivo deamidation of the asparagine situated at position beta 82. Cellulose acetate and citrate agar electrophoresis of hemolysates from patients with this abnormality shows three bands. Globin chain electrophoresis at acid and alkaline pH shows three beta chains. These three chains correspond to the normal beta A chain and two abnormal beta chains. Sequence analysis indicates that the two abnormal chains differ from beta A at only position beta 82. In the two abnormal chains, the residue which is normally lysine is substituted either by asparagine or by aspartic acid. These substitutions are notable because beta 82 lysine is one of the residues involved in 2,3-diphosphoglycerate binding. Additionally, beta 82 lysine is typically invariant in hemoglobin beta chain sequences. Sequence data on the two forms of Hemoglobin Providence are given in this paper. The functional properties of these two forms are described in the next paper.  (+info)

Merbarone, a catalytic inhibitor of DNA topoisomerase II, induces apoptosis in CEM cells through activation of ICE/CED-3-like protease. (2/1939)

Merbarone (5-[N-phenyl carboxamido]-2-thiobarbituric acid) is an anticancer drug that inhibits the catalytic activity of DNA topoisomerase II (topo II) without damaging DNA or stabilizing DNA-topo II cleavable complexes. Although the cytotoxicity of the complex-stabilizing DNA-topo II inhibitors such as VP-16 (etoposide) has been partially elucidated, the cytotoxicity of merbarone is poorly understood. Here, we report that merbarone induces programmed cell death or apoptosis in human leukemic CEM cells, characterized by internucleosomal DNA cleavage and nuclear condensation. Treatment of CEM cells with apoptosis-inducing concentrations of merbarone caused activation of c-Jun NH2-terminal kinase/stress-activated protein kinase, c-jun gene induction, activation of caspase-3/CPP32-like protease but not caspase-1, and the proteolytic cleavage of poly(ADP-ribose) polymerase. Treatment of CEM cells with a potent inhibitor of caspases, Z-Asp-2. 6-dichlorobenzoyloxymethyl-ketone, inhibited merbarone-induced caspase-3/CPP32-like activity and apoptosis in a dose-dependent manner. These results indicate that the catalytic inhibition of topo II by merbarone leads to apoptotic cell death through a caspase-3-like protease-dependent mechanism. These results further suggest that c-Jun and c-Jun NH2-terminal kinase/stress-activated protein kinase signaling may be involved in the cytotoxicity of merbarone.  (+info)

Distortion of the L-->M transition in the photocycle of the bacteriorhodopsin mutant D96N: a time-resolved step-scan FTIR investigation. (3/1939)

The D96N mutant of bacteriorhodopsin has often been taken as a model system to study the M intermediate of the wild type photocycle due to the long life time of the corresponding intermediate of the mutant. Using time-resolved step-scan FTIR spectroscopy in combination with a sample changing wheel we investigated the photocycle of the mutant with microsecond time resolution. Already after several microseconds an intermediate similar to the MN state is observed, which contrasts with the M state of the wild type protein. At reduced hydration M and N intermediates similar to those of wild type BR can be detected. These results have a bearing on the interpretation of the photocycle of this mutant. A mechanism is suggested for the fast rise of MN which provides some insight into the molecular events involved in triggering the opening of the cytosolic channel also of the wild type protein.  (+info)

Interaction of asparagine and EGF in the regulation of ornithine decarboxylase in IEC-6 cells. (4/1939)

Our laboratory has shown that asparagine (ASN) stimulates both ornithine decarboxylase (ODC) activity and gene expression in an intestinal epithelial cell line (IEC-6). The effect of ASN is specific, and other A- and N-system amino acids are almost as effective as ASN when added alone. In the present study, epidermal growth factor (EGF) was unable to increase ODC activity in cells maintained in a salt-glucose solution (Earle's balanced salt solution). However, the addition of ASN (10 mM) in the presence of EGF (30 ng/ml) increased the activity of ODC 0.5- to 4-fold over that stimulated by ASN alone. EGF also showed induction of ODC with glutamine and alpha-aminoisobutyric acid, but ODC induction was maximum with ASN and EGF. Thus the mechanism of the interaction between ASN and EGF is important for understanding the regulation of ODC under physiological conditions. Therefore, we examined the expression of the ODC gene and those for several protooncogenes under the same conditions. Increased expression of the genes for c-Jun and c-Fos but not for ODC occurred with EGF alone. The addition of ASN did not further increase the expression of the protooncogenes, but the combination of EGF and ASN further increased the expression of ODC over that of ASN alone. Western analysis showed no significant difference in the level of ODC protein in Earle's balanced salt solution, ASN, EGF, or EGF plus ASN. Addition of cycloheximide during ASN and ASN plus EGF treatment completely inhibited ODC activity without affecting the level of ODC protein. These results indicated that 1) the increased expression of protooncogenes in response to EGF is independent of increases in ODC activity and 2) potentiation between EGF and ASN on ODC activity may not be due to increased gene transcription but to posttranslational regulation and the requirement of ongoing protein synthesis involving a specific factor dependent on ASN.  (+info)

Glycosylation of asparagine-28 of recombinant staphylokinase with high-mannose-type oligosaccharides results in a protein with highly attenuated plasminogen activator activity. (5/1939)

The properties of recombinant staphylokinase (SakSTAR) expressed in Pichia pastoris cells have been determined. The single consensus N-linked oligosaccharide linkage site in SakSTAR (at Asn28 of the mature protein) was occupied in approximately 50% of the expressed protein with high-mannose-type oligosaccharides. The majority of these glycans ranged in polymerization state from Man8GlcNAc2 to Man14GlcNAc2, with the predominant species being Man10GlcNAc2 and Man11GlcNAc2. Glycosylated SakSTAR (SakSTARg) did not differ from its aglycosyl form in its aggregation state in solution, its thermal denaturation properties, its ability to form a complex with human plasmin (hPm), the amidolytic properties of the respective SakSTAR-hPm complexes, or its ability to liberate the amino-terminal decapeptide required for formation of a functional SakSTAR-hPm plasminogen activator complex. However, this latter complex with SakSTARg showed a greatly reduced ability to activate human plasminogen (hPg) as compared with the same complex with the aglycosyl form of SakSTAR. We conclude that glycosylation at Asn28 does not affect the structural properties of SakSTAR or its ability to participate in the formation of an active enzymatic complex with hPm, but it is detrimental to the ability of the SakSTAR-hPm complex to serve as a hPg activator. This is likely due to restricted access of hPg to the active site of the SakSTARg-hPm complex.  (+info)

The presence of pseudouridine in the anticodon alters the genetic code: a possible mechanism for assignment of the AAA lysine codon as asparagine in echinoderm mitochondria. (6/1939)

It has been inferred from DNA sequence analyses that in echinoderm mitochondria not only the usual asparagine codons AAU and AAC, but also the usual lysine codon AAA, are translated as asparagine by a single mitochondrial (mt) tRNAAsn with the anticodon GUU. Nucleotide sequencing of starfish mt tRNAAsn revealed that the anticodon is GPsiU, U35 at the anticodon second position being modified to pseudouridine (Psi). In contrast, mt tRNALys, corresponding to another lysine codon, AAG, has the anticodon CUU. mt tRNAs possessing anti-codons closely related to that of tRNAAsn, but responsible for decoding only two codons each-tRNAHis, tRNAAsp and tRNATyr-were found to possess unmodified U35 in all cases, suggesting the importance of Psi35 for decoding the three codons. Therefore, the decoding capabilities of two synthetic Escherichia coli tRNAAla variants with the anticodon GPsiU or GUU were examined using an E.coli in vitro translation system. Both tRNAs could translate not only AAC and AAU with similar efficiency, but also AAA with an efficiency that was approximately 2-fold higher in the case of tRNAAlaGPsiU than tRNAAlaGUU. These findings imply that Psi35 of echinoderm mt tRNAAsn actually serves to decode the unusual asparagine codon AAA, resulting in the alteration of the genetic code in echinoderm mitochondria.  (+info)

L-Asparagine synthetase in serum as a marker for neoplasia. (7/1939)

L-Asparagine synthetase appears in serum approximately 7 days after the s.c. implantation of 1 X 10(5) cells of Leukemia 5178Y/AR (resistant to L-asparaginase) and increases in activity as the neoplasm grows and metastasizes. The principal source of the enzyme is the primary tumor. After intravranial inoculation of tumor, the rate of leakage of the enzyme is more pronounced than when the subcutaneous, intramuscular, or intraperitoneal routes are used. 1-(2-Chloroethyl)-3-cyclohexyl-1-nitrosourea (NSC 79037), a nitro-sourea effective in the palliation of L5178Y/AR, temporarily halts the influx of enzyme into the blood stream, as does surgical excision of the s.c. tumor nodules. Treatment of mice with L-asparaginase within 24 hr of inoculation of the tumor markedly augments both tumor growth and the rate of penetration of L-asparagine synthetase into the circulation. Several other L-asparagine synthetase into the circulation. Several other L-asparaginase-resistant tumors also were found to spill L-asparagine synthetase into the serum, but the correlation between this phenomenon and the specific activity of the enzyme in homogenates of the tumor was imperfect.  (+info)

Conserved polar residues in the transmembrane domain of the human tachykinin NK2 receptor: functional roles and structural implications. (8/1939)

We have studied the effects of agonist and antagonist binding, agonist-induced activation and agonist-induced desensitization of the human tachykinin NK2 receptor mutated at polar residues Asn-51 [in transmembrane helix 1 (TM1)], Asp-79 (TM2) and Asn-303 (TM7), which are highly conserved in the transmembrane domain in the rhodopsin family of G-protein-coupled receptors. Wild-type and mutant receptors were expressed in both COS-1 cells and Xenopus oocytes. The results show that the N51D mutation results in a receptor which, in contrast with the wild-type receptor, is desensitized by the application of a concentration of 1 microM of the partial agonist GR64349, indicating that the mutant is more sensitive to agonist activation than is the wild-type receptor. In addition, we show that, whereas the D79E mutant displayed activation properties similar to those of the wild-type receptor, the D79N and D79A mutants displayed a severely impaired ability to activate the calcium-dependent chloride current. This suggests that it is the negative charge at Asn-79, rather than the ability of this residue to hydrogen-bond, that is critical for the activity of the receptor. Interestingly, the placement of a negative charge at position 303 could compensate for the removal of the negative charge at position 79, since the double mutant D79N/N303D displayed activation properties similar to those of the wild-type receptor. This suggests that these two residues are functionally coupled, and may even be in close proximity in the three-dimensional structure of the human tachykinin NK2 receptor. A three-dimensional model of the receptor displaying this putative interaction is presented.  (+info)

A method to assess compositional bias in biological sequences and its application to prion-like glutamine/asparagine-rich...A method to assess compositional bias in biological sequences and its application to prion-like glutamine/asparagine-rich...
We have derived a novel method to assess compositional biases in biological sequences, which is based on finding the lowest-probability subsequences for a given residue-type set. As a case study, the distribution of prion-like glutamine/asparagine-rich ((Q+N)-rich) domains (which are linked to amyloidogenesis) was assessed for budding and fission yeasts and four other eukaryotes. We find more than 170 prion-like (Q+N)-rich regions in budding yeast, and, strikingly, many fewer in fission yeast. Also, some residues, such as tryptophan or isoleucine, are unlikely to form biased regions in any eukaryotic proteome.

An antigenic peptide produced by reverse splicing and double asparagine deamidation. - Nuffield Department of MedicineAn antigenic peptide produced by reverse splicing and double asparagine deamidation. - Nuffield Department of Medicine
A variety of unconventional translational and posttranslational mechanisms contribute to the production of antigenic peptides, thereby increasing the diversity of the peptide repertoire presented by MHC class I molecules. Here, we describe a class I-restricted peptide that combines several posttranslational modifications. It is derived from tyrosinase and recognized by tumor-infiltrating lymphocytes isolated from a melanoma patient. This unusual antigenic peptide is made of two noncontiguous tyrosinase fragments that are spliced together in the reverse order. In addition, it contains two aspartate residues that replace the asparagines encoded in the tyrosinase sequence. We confirmed that this peptide is naturally presented at the surface of melanoma cells, and we showed that its processing sequentially requires translation of tyrosinase into the endoplasmic reticulum and its retrotranslocation into the cytosol, where deglycosylation of the two asparagines by peptide-N-glycanase turns them into

Synapsin I is structurally similar to ATP‐utilizing enzymes | The EMBO JournalSynapsin I is structurally similar to ATP‐utilizing enzymes | The EMBO Journal
The structure of synC can be divided into three subdomains (Figure 1D): the amino‐terminal subdomain (residues 110‐223), the central subdomain (residues 246‐308) and the carboxy‐terminal subdomain (residues 224‐245 and 309‐420). The core of the amino‐terminal subdomain is a four‐stranded parallel β‐sheet (β1, β2, β6, β7), which is flanked by a helical loop (residues 124‐137) and helix α1. It resembles the nucleotide‐binding motif (NAD motif) found in numerous enzymes that bind substrates at the carboxyl end of the parallel β‐sheet. The parallel arrangement of helices α1 and α2 and their connection by strand β7 are remarkably well conserved in synC and GSHase. Even more remarkable is the existence of a cis‐asparagine residue at the carboxyl end of strand β7 in both synC (Asn214) and GSHase (Asn114). As the cis conformation is extremely rare in peptide bonds preceding residues other than proline, the use of cis‐asparagine at equivalent positions in synC and ...

Although bafilomycin induced HIF-1α levels under normoxic conditions, it has little effect on the expressions of HIF-1 targeted genes. This effect of bafilomycin on HIF-1α could be suspected of the factor-inhibiting HIF (FIH). In the absence of a hypoxic signal, HIF-1α can be inactivated by FIH. FIH hydroxylates an asparagine residue (Asn803) within the transactivation domain of HIF-1α, which blocks its recruitment of p300 coactivator (Lando et al., 2002). Moreover, under hypoxic conditions, asparagine hydroxylation is inhibited due to limited oxygen, and HIF-1α remains unmodified and activated. This seems to be one of the reasons why HIF-1α induced by bafilomycin has little transcriptional activity; similarly, HIF-1α induced by heat shock was found to have no transcriptional activity (Katschinski et al., 2002). However, HIF-1α induced by bafilomycin induced p21 transcription. Recently, Koshiji et al. (2004) demonstrated the mechanism of p21 induction by HIF-1α (i.e., c-Myc represses ...

This sequence change replaces histidine with asparagine at codon 6717 of the SYNE1 protein (p.His6717Asn). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and asparagine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SYNE1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance ...

The asparaginyl hydroxylase FIH [factor inhibiting HIF (hypoxia-inducible factor)] was first identified as a protein that inhibits transcriptional activation by HIF, through hydroxylation of an asparagine residue in the CAD (C-terminal activation domain). More recently, several ARD [AR (ankyrin repeat) domain]-containing proteins were identified as FIH substrates using FIH interaction assays. Although the function(s) of these ARD hydroxylations is unclear, expression of the ARD protein Notch1 was shown to compete efficiently with HIF CAD for asparagine hydroxylation and thus to enhance HIF activity. The ARD is a common protein domain with over 300 examples in the human proteome. However, the extent of hydroxylation among ARD proteins, and the ability of other members to compete with HIF-CAD for FIH, is not known. In the present study we assay for asparagine hydroxylation in a bioinformatically predicted FIH substrate, the targeting subunit of myosin phosphatase, MYPT1. Our results confirm hydroxylation

Activity of the hypoxia-inducible factor (HIF) complex is controlled by oxygen-dependent hydroxylation of prolyl and asparaginyl residues. Hydroxylation of specific prolyl residues by 2-oxoglutarate (2-OG)-dependent oxygenases mediates ubiquitinylation and proteasomal destruction of HIF-alpha. Hydroxylation of an asparagine residue in the C-terminal transactivation domain (CAD) of HIF-alpha abrogates interaction with p300, preventing transcriptional activation. Yeast two-hybrid assays recently identified factor inhibiting HIF (FIH) as a protein that associates with the CAD region of HIF-alpha. Since FIH contains certain motifs present in iron- and 2-OG-dependent oxygenases we investigated whether FIH was the HIF asparaginyl hydroxylase. Assays using recombinant FIH and HIF-alpha fragments revealed that FIH is the enzyme that hydroxylates the CAD asparagine residue, that the activity is directly inhibited by cobalt(II) and limited by hypoxia, and that the oxygen in the alcohol of the hydroxyasparagine

Human Metabolome Database: Showing metabocard for L-Asparagine (HMDB0000168)Human Metabolome Database: Showing metabocard for L-Asparagine (HMDB0000168)
Asparagine (Asn) is one of the 20 most common natural amino acids on Earth. It has carboxamide as the side chains functional group. Asparagine is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. The precursor to asparagine is oxaloacetate. Oxaloacetate is converted to aspartate using a transaminase enzyme. The enzyme transfers the amino group from glutamate to oxaloacetate producing alpha-ketoglutarate and aspartate. The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. In the asparagine synthetase reaction, ATP is used to activate aspartate, forming beta-aspartyl-AMP. Glutamine donates an ammonium group which reacts with beta-aspartyl-AMP to form asparagine and free AMP. Since the asparagine side chain can make efficient hydrogen bond interactions with the peptide backbone, asparagines are often found near the beginning ...

Amyloid-Mediated Sequestration of Essential Proteins Contributes to Mutant Huntingtin Toxicity in YeastAmyloid-Mediated Sequestration of Essential Proteins Contributes to Mutant Huntingtin Toxicity in Yeast
Background Polyglutamine expansion is responsible for several neurodegenerative disorders, among which Huntington disease is the most well-known. Studies in the yeast model demonstrated that both aggregation and toxicity of a huntingtin (htt) protein with an expanded polyglutamine region strictly depend on the presence of the prion form of Rnq1 protein ([PIN+]), which has a glutamine/asparagine-rich domain. Principal Findings Here, we showed that aggregation and toxicity of mutant htt depended on [PIN+] only quantitatively: the presence of [PIN+] elevated the toxicity and the levels of htt detergent-insoluble polymers. In cells lacking [PIN+], toxicity of mutant htt was due to the polymerization and inactivation of the essential glutamine/asparagine-rich Sup35 protein and related inactivation of another essential protein, Sup45, most probably via its sequestration into Sup35 aggregates. However, inhibition of growth of [PIN+] cells depended on Sup35/Sup45 depletion only partially, suggesting that

Asparagine. Molecular model of the amino acid asparagine. Its chemical formula is C4.H8.N2.O3. Atoms are represented as spheres and are colour- coded: carbon (blue), hydrogen (gold), oxygen (red) and nitrogen (dark blue). Amino acids are the building blocks of proteins. Asparagine is a non-essential amino acid. It can be synthesised by the body and so does not need to come from the diet. Asparagine plays an important role in the folding of protein molecules into their secondary structures (alpha helices and beta sheets). Some proteins (such as haemoglobin, the oxygen- carrying pigment in human blood) cannot function without being folded into the correct shape. - Stock Image A611/0042

The mechanism by which asparaginase inhibits the 6C3HED tumor is probably not directly related to the cellular concentration of asparagine, since the concentration of asparagine decreases in resistant tumors, spleen, and liver, as well as in susceptible tumors. Amino acids other than asparagine may be affected by asparaginase because of the variety of metabolic relationships of the amino acids. In this study, analyses of all the amino acids of resistant 6C3HED tumor, susceptible 6C3HED tumor, spleen, and liver were undertaken.. Most of the amino acids of the susceptible tumor increased from 2- to 40-fold, while only slight changes occurred in the resistant tumor. The most dramatic change was a decrease in glycine in the susceptible tumor. No parallel change in glycine occurred in the resistant tumor, the spleen, or the liver. It is suggested that the susceptible tumor may synthesize glycine from asparagine; consequently, the decrease in asparagine is followed by a decrease in cellular glycine. ...

Most core residues of coiled coils are hydrophobic. Occasional polar residues are thought to lower stability, but impart structural specificity. The coiled coils of trimeric autotransporter adhesins (TAAs) are conspicuous for their large number of polar residues in position d of the core, which often leads to their prediction as natively unstructured regions. The most frequent residue, asparagine ([email protected]), can occur in runs of up to 19 consecutive heptads, frequently in the motif [I/V]xxNTxx. In the Salmonella TAA, SadA, the core asparagines form rings of interacting residues with the following threonines, grouped around a central anion. This conformation is observed generally in [email protected] layers from trimeric coiled coils of known structure. Attempts to impose a different register on the motif show that the asparagines orient themselves specifically into the core, even against conflicting information from flanking domains. When engineered into the GCN4 leucine zipper, [email protected] layers progressively ...

The antileukemic activity of l-asparaginase (ASNase), an important component of therapy for acute lymphoblastic leukemia, is thought to result from depletion of serum l-asparagine (Asn). In studies of the pharmacological effects of ASNase, investigators have reported prolonged reduction in the serum concentration of Asn after the administration of ASNase. Such measurements may not be valid because ASNase present in the blood sample may hydrolyze Asn before its determination. We examined recovery of [U-14C]Asn from blood samples with and without various concentrations of added ASNase. In the presence of ≥0.01 IU/ml of ASNase, the amount of [U-14C]Asn recovered was ,15% of that without ASNase. Utilizing this assay, we studied the effect of 2 known inhibitors of ASNase in an attempt to improve Asn recovery. In the presence of aspartic β semialdehyde (ASA), or 5-diazo-4-oxo-l-norvaline (DONV), and up to 1.0 IU/ml ASNase, Asn levels remained at ,90% of control. ASA prevented the hydrolysis of ...

Targeting amino acid metabolism has therapeutic implications for aggressive brain tumors. Asparagine is an amino acid that is synthesized by normal cells. However, some cancer cells lack asparagine synthetase (ASNS), the key enzyme for asparagine synthesis. Asparaginase (ASNase) contributes to eradication of acute leukemia by decreasing asparagine levels in serum and cerebrospinal fluid. However, leukemic cells may become ASNase-resistant by up-regulating ASNS. High expression of ASNS has also been associated with biological aggressiveness of other cancers, including gliomas. Here, the impact of enzymatic depletion of asparagine on proliferation of brain tumor cells was determined. ASNase was used as monotherapy or in combination with conventional chemotherapeutic agents. Viability assays for ASNase-treated cells demonstrated significant growth reduction in multiple cell lines. This effect was reversed by glutamine in a dose-dependent manner -- as expected, because glutamine is the main amino ...

HIF plays a central role in the transcriptional response to changes in oxygen availability. The PHD family of oxygen-dependent prolyl hydroxylases plays a pivotal role in regulating HIF stability. The biochemical properties of these enzymes make them well suited to act as oxygen sensors. They also respond to other intracellular signals, including reactive oxygen species, nitric oxide, and certain metabolites, that can modulate the hypoxic response. HIF transcriptional activity is further tuned by FIH1-mediated asparagine hydroxylation. HIF affects signaling pathways that influence development, metabolism, inflammation, and integrative physiology. Accordingly, HIF-modulatory drugs are now being developed for diverse diseases.

AsparaginAsparagin
Asparagine (abbreviated as Asn or N; Asx or B represent either asparagine or aspartic acid) is one of the 20 most common natural amino acids on Earth. It has carboxamide as the side chains functional group. It is not an essential amino acid. Its codons are AAU and AAC. A reaction between asparagine and reducing sugars or reactive carbonyls produces acrylamide (acrylic amide) in food when heated to sufficient temperature. These products occur in baked goods such as french fries, potato chips, and roasted coffee.

Background Voltage-dependent block from the NMDA receptor by Mg2+ is usually thought to be central to the unique involvement of this receptor in higher brain functions. hippocampal spatial info processing by attenuating activity-dependent synaptic potentiation in the dentate gyrus. overexpressing an NMDAR defective for Mg2+ block has problems in long-term memory space [7]. However, the role of the Mg2+ block in vertebrates still remains unclear. NMDARs defective for the Mg2+ block cause perinatal lethality in mice expressing these receptors [8]. A single amino acid substitution is known to greatly switch the Mg2+ blockade of the NMDAR. Practical NMDARs are likely hetero-oligomers comprising two types of subunits, GluN1 and GluN2. Each subunit offers four expected membrane-associated segments (M1CM4). A single asparagine residue in M2 is critical for voltage-dependent Mg2+ blockade. Alternative of asparagine 598 of the GluN1 subunit with glutamine strongly reduces the level of sensitivity of the ...

Amino AcidsPhysicochemical difference between asparagineAsparticResiduesGlutamineSynthetaseThreonineMetabolismLysineDerivativesSequenceSynthesisAcrylamideAmmoniaCompoundCellularCellsNaturalExpressionActivity
Amino Acids3
  • In return, bacteroids act like plant organelles to cycle amino acids back to the plant for asparagine synthesis. (ox.ac.uk)
  • 0.790g asparagine and 0.294g hydroxyproline (both free form amino acids) were found. (priceplow.com)
  • It is also a source of essential amino acids such as leucine, aspartic acid and asparagine. (antakiayoresel.com)
Physicochemical difference between asparagine1
  • The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and threonine. (utah.edu)
Aspartic5
  • This mutation replaces the amino acid asparagine with the amino acid aspartic acid at protein position 314 (written as Asn314Asp or N314D). (medlineplus.gov)
  • Its use in anti-cancer therapy is based on its ability to cleave L-asparagine, an amino acid essential for the growth of lymphoblasts, to ammonia and L-aspartic acid in serum and cerebrospinal fluid. (pjmonline.org)
  • L-asparaginase, produced mainly by microrganisms, cleaves L-asparagine to aspartic acid and ammonia as products. (sci-rep.com)
  • The filtrate was used to determine the L-asparaginase activity through the hydroximate aspartic methodology using L-asparagine as substrate. (sci-rep.com)
  • This sequence change replaces aspartic acid with asparagine at codon 181 of the SDHB protein (p.Asp181Asn). (utah.edu)
Residues3
  • The present structures in a lipid bilayer revealed the detailed mechanism for the tetrameric assembly of PepT So2 , in which a characteristic extracellular loop (ECL) interacts with two asparagine residues on H12 which were reported to be important for tetramerization and plays an essential role in oligomeric assembly. (rcsb.org)
  • The Protein Deglycosylation Mix II includes the enzymes necessary to remove carbohydrates attached to Asparagine residues, simple core 1 and core 3 O-linked carbohydrates attached to Ser/Thr, and decorated core 1 and 3 O-glycans (with lactosamine extensions). (neb.com)
  • Residues with low binding energy to asparagine (Asn) and high binding energy to glutamine (Gln) were chosen for mutagenesis. (waocp.org)
Glutamine1
  • The Company's lead product candidate, eryaspase, which consists of L-asparaginase encapsulated inside donor-derived red blood cells, targets the cancer cell's altered asparagine and glutamine metabolism. (yahoo.com)
Synthetase2
  • Ryder, now 4.5 years old, had a condition called Asparagine Synthetase Deficiency Disorder. (cincinnatichildrens.org)
  • Asparagine synthetase (ASNS) catalyses the ATP-dependent conversion of aspartate to asparagine. (biocytogen.com)
Threonine2
  • The asparagine at codon 194 is replaced by threonine, an amino acid with similar properties. (utah.edu)
  • This sequence change replaces asparagine with threonine at codon 194 of the TNNI3 protein (p.Asn194Thr). (utah.edu)
Metabolism2
  • Thus, we found that p53 regulates asparagine metabolism and dictates cell survival by generating an auto-amplification loop via asparagine-aspartate-mediated LKB1-AMPK signalling. (biocytogen.com)
  • Our findings highlight a role for LKB1 in sensing asparagine and aspartate and connect asparagine metabolism to the cellular signalling transduction network that modulates cell survival. (biocytogen.com)
Lysine1
  • This sequence change replaces asparagine with lysine at codon 436 of the DSG2 protein (p.Asn436Lys). (utah.edu)
Derivatives1
  • The syntheses and crystal structures of six substituted benzenesulfonyl-asparagine derivatives are reported. (elsevier.com)
Sequence1
  • This sequence change replaces asparagine with serine at codon 162 of the BBS2 protein (p.Asn162Ser). (utah.edu)
Synthesis1
  • Here, we report that p53 suppresses asparagine synthesis through the transcriptional downregulation of ASNS expression and disrupts asparagine-aspartate homeostasis, leading to lymphoma and colon tumour growth inhibition in vivo and in vitro. (biocytogen.com)
Acrylamide4
  • Acrylamide forms when the amino acid asparagine reacts with sugar in foods. (vitacost.com)
  • The application protects the company's work over the last two years in developing baker's yeast strains (Saccharomyces cerevisiae) that reduces acrylamide by up to 95 per cent in a variety of food products by degrading the precursor compound asparagine. (foodmag.com.au)
  • Acrylamide is not added to foods, but forms naturally from the amino acid asparagine when foods are heated above 120 °C (e.g. baking, roasting, or frying). (foodmag.com.au)
  • Renaissance Ingredients' AR yeast strains are traditional baker's yeast with an accelerated natural ability to consume asparagine, thereby reducing acrylamide. (foodmag.com.au)
Ammonia1
  • L-asparagine aminohydrolase) catalyzes the deamination of L-asparagine (Asn) to L-aspartate and ammonia. (pjmonline.org)
Compound2
  • At the time the patent was filed, it was universally believed that the daptomycin compound included the L-isomer of asparagine. (jdsupra.com)
  • In particular, because the "specification as a whole" made clear that the compound being claimed as "Formula 3" was always intended to be the prior art compound daptomycin, "D-asparagine was covered both before and after correction. (jdsupra.com)
Cellular1
  • eIF4B enhances ATF4 expression and contributes to cellular adaptation to asparagine limitation in BRAF-mutated A375 melanoma. (or.jp)
Cells1
  • Since lymphoblasts are unable to produce endogenous L-asparagine, starvation for this amino acid leads to the death of these cells (Kotzia and Labrou, 2007). (pjmonline.org)
Natural1
Expression1
Activity1
  • Mechanistically, asparagine and aspartate regulate AMPK-mediated p53 activation by physically binding to LKB1 and oppositely modulating LKB1 activity. (biocytogen.com)
