A new yeast metabolon involving at least the two first enzymes of arginine biosynthesis: acetylglutamate synthase activity requires complex formation with acetylglutamate kinase. (1/65)

Open reading frame YJL071W of Saccharomyces cerevisiae was shown to be ARG2 and identified as the structural gene for acetylglutamate synthase, first step in arginine biosynthesis. The three Ascomycete acetylglutamate synthases characterized to date appear homologous, but unlike the other enzymes of the yeast arginine biosynthesis pathway, they showed no significant similarity to their prokaryotic equivalents. The measured synthase activity did not increase with the number of ARG2 gene copies unless the number of ARG5,6 gene copies was increased similarly. ARG5,6 encodes a precursor that is maturated in the mitochondria into acetylglutamate kinase and acetylglutamyl-phosphate reductase, catalyzing the second and third steps in the pathway. The results imply that the synthase must interact stoichiometrically in vivo with the kinase, the reductase, or both to be active. Results obtained with synthetic ARG5 and ARG6 genes suggested that both the kinase and the reductase could be needed. This situation, which has completely escaped notice in yeast until now, is reminiscent of the observation in Neurospora crassa that nonsense arg-6 kinase/reductase mutants lack synthase activity (Hinde, R. W., Jacobson, J. A., Weiss, R. L., and Davis, R. H. (1986) J. Biol. Chem. 261, 5848-5852). In immunoprecipitation experiments, hemagglutinin-tagged synthase coprecipitated with a protein proven by microsequencing to be the kinase. Western blot analyses showed that the synthase has reduced stability in the absence of the kinase/reductase. Our data demonstrate the existence of a new yeast arginine metabolon involving at least the first two, and possibly the first three, enzymes of the pathway. Hypotheses regarding the biological significance of this interaction are discussed.  (+info)

Identification, cloning and expression of the mouse N-acetylglutamate synthase gene. (2/65)

In ureotelic animals, N-acetylglutamate (NAG) is an essential allosteric activator of carbamylphosphate synthetase I (CPSI), the first enzyme in the urea cycle. NAG synthase (NAGS; EC 2.3.1.1) catalyses the formation of NAG from glutamate and acetyl-CoA in liver and intestinal mitochondria. This enzyme is supposed to regulate ureagenesis by producing variable amounts of NAG, thus modulating CPSI activity. Moreover, inherited deficiencies in NAGS have been associated with hyperammonaemia, probably due to the loss of CPSI activity. Although the existence of the NAGS protein in mammals has been known for decades, the gene has remained elusive. We identified the mouse (Mus musculus) and human NAGS genes using their similarity to the respective Neurospora crassa gene. NAGS was cloned from a mouse liver cDNA library and was found to encode a 2.3 kb message, highly expressed in liver and small intestine with lower expression levels in kidney, spleen and testis. The deduced amino acid sequence contains a putative mitochondrial targeting signal at the N-terminus. The cDNA sequence complements an argA (NAGS)-deficient Escherichia coli strain, reversing its arginine auxotrophy. His-tagged versions of the pre-protein and two putative mature proteins were each overexpressed in E. coli, and purified to apparent homogeneity by using a nickel-affinity column. The pre-protein and the two putative mature proteins catalysed the NAGS reaction but one of the putative mature enzymes had significantly higher activity than the pre-protein. The addition of l-arginine increased the catalytic activity of the purified recombinant NAGS enzymes by approx. 2-6-fold.  (+info)

The N-acetylglutamate synthase/N-acetylglutamate kinase metabolon of Saccharomyces cerevisiae allows co-ordinated feedback regulation of the first two steps in arginine biosynthesis. (3/65)

In Saccharomyces cerevisiae, which uses the nonlinear pathway of arginine biosynthesis, the first two enzymes, N-acetylglutamate synthase (NAGS) and N-acetylglutamate kinase (NAGK), are controlled by feedback inhibition. We have previously shown that NAGS and NAGK associate in a complex, essential to synthase activity and protein level [Abadjieva, A., Pauwels, K., Hilven, P. & Crabeel, M. (2001) J. Biol. Chem.276, 42869-42880]. The NAGKs of ascomycetes possess, in addition to the catalytic domain that is shared by all other NAGKs and whose structure has been determined, a C-terminal domain of unknown function and structure. Exploring the role of these two domains in the synthase/kinase interaction, we demonstrate that the ascomycete-specific domain is required to maintain synthase activity and protein level. Previous results had suggested a participation of the third enzyme of the pathway, N-acetylglutamylphosphate reductase, in the metabolon. Here, genetic analyses conducted in yeast at physiological level, or in a heterologous background, clearly demonstrate that the reductase is dispensable for synthase activity and protein level. Most importantly, we show that the arginine feedback regulation of the NAGS and NAGK enzymes is mutually interdependent. First, the kinase becomes less sensitive to arginine feedback inhibition in the absence of the synthase. Second, and as in Neurospora crassa, in a yeast kinase mutant resistant to arginine feedback inhibition, the synthase becomes feedback resistant concomitantly. We conclude that the NAGS/NAGK metabolon promotes the co-ordination of the catalytic activities and feedback regulation of the first two, flux controlling, enzymes of the arginine pathway.  (+info)

Mammalian N-acetylglutamate synthase. (4/65)

N-Acetylglutamate synthase (NAGS, E.C. 2.3.1.1) is a mitochondrial enzyme that catalyzes the formation of N-acetylglutamate (NAG), an essential allosteric activator of carbamylphosphate synthetase I (CPSI). The mouse and human NAGS genes have been identified based on similarity to regions of NAGS from Neurospora crassa and cloned from liver cDNA libraries. These genes were shown to complement an argA- (NAGS) deficient Escherichia coli strain, and enzymatic activity of the proteins was confirmed by a new stable isotope dilution assay. The deduced amino acid sequence of mammalian NAGS contains a putative mitochondrial-targeting signal at the N-terminus. The mouse NAGS preprotein was overexpressed in insect cells to determine post-translational modifications and two processed proteins with different N-terminal truncations have been identified. Sequence analysis using a hidden Markov model suggests that the vertebrate NAGS protein contains domains with a carbamate kinase fold and an acyl-CoA N-acyltransferase fold, and protein crystallization experiments are currently underway. Inherited NAGS deficiency results in hyperammonemia, presumably due to the loss of CPSI activity. We, and others, have recently identified mutations in families with neonatal and late-onset NAGS deficiency and the identification of the gene has now made carrier testing and prenatal diagnosis feasible. A structural analog of NAG, carbamylglutamate, has been shown to bind and activate CPSI, and several patients have been reported to respond favorably to this drug (Carbaglu).  (+info)

Functional characterization of a novel ArgA from Mycobacterium tuberculosis. (5/65)

The Mycobacterium tuberculosis gene Rv2747 encodes a novel 19-kDa ArgA that catalyzes the initial step in L-arginine biosynthesis, namely the conversion of L-glutamate to alpha-N-acetyl-L-glutamate. Initial velocity studies reveal that Rv2747 proceeds through a sequential kinetic mechanism, with K(m) values of 280 mM for L-glutamine and 150 microM for acetyl-coenzyme A and with a k(cat) value of 200 min(-1). Initial velocity studies with L-glutamate showed that even at concentrations of 600 mM, saturation was not observed. Therefore, only a k(cat)/K(m) value of 125 M(-1) min(-1) can be calculated. Inhibition studies reveal that the enzyme is strongly regulated by L-arginine, the end product of the pathway (50% inhibitory concentration, 26 microM). The enzyme was completely inhibited by 500 microM arginine, with a Hill coefficient of 0.60, indicating negatively cooperative binding of L-arginine.  (+info)

Identification of novel mutations of the human N-acetylglutamate synthase gene and their functional investigation by expression studies. (6/65)

The mitochondrial enzyme N-acetylglutamate synthase (NAGS) produces N-acetylglutamate serving as an allosteric activator of carbamylphosphate synthetase 1, the first enzyme of the urea cycle. Autosomal recessively inherited NAGS deficiency (NAGSD) leads to severe neonatal or late-onset hyperammonemia. To date few patients have been described and the gene involved was described only recently. In this study, another three families affected by NAGSD were analyzed for NAGS gene mutations resulting in the identification of three novel missense mutations (C200R [c.598T > C], S410P [c.1228T > C], A518T [c.1552G > A]). In order to investigate the effects of these three and two additional previously published missense mutations on enzyme activity, the mutated proteins were overexpressed in a bacterial expression system using the NAGS deficient E. coli strain NK5992. All mutated proteins showed a severe decrease in enzyme activity providing evidence for the disease-causing nature of the mutations. In addition, we expressed the full-length NAGS wild type protein including the mitochondrial leading sequence, the mature protein as well as a highly conserved core protein. NAGS activity was detected in all three recombinant proteins but varied regarding activity levels and response to stimulation by l-arginine. In conclusion, overexpression of wild type and mutated NAGS proteins in E. coli provides a suitable tool for functional analysis of NAGS deficiency.  (+info)

Translocation of a long amino-terminal domain through ER membrane by following signal-anchor sequence. (7/65)

Type I signal-anchor sequences mediate translocation of the N-terminal domain (N-domain) across the endoplasmic reticulum (ER) membrane. To examine the translocation in detail, dihydrofolate reductase (DHFR) was fused to the N-terminus of synaptotagmin II as a long N-domain. Translocation was arrested by the DHFR ligand methotrexate, which stabilizes the folding of the DHFR domain, and resumed after depletion of methotrexate. The targeting of the ribosome-nascent chain complex to the ER requires GTP, whereas N-domain translocation does not require any nucleotide triphosphates. Significant translocation was observed even in the absence of a lumenal hsp70 (BiP). When the nascent polypeptide was released from the ribosomes after the membrane targeting, the N-domain translocation was suppressed and the nascent chain was released from the translocon. Ribosomes have a crucial role in maintaining the translocation-intermediate state. The translocation of the DHFR domain was greatly impaired when it was separated from the signal-anchor sequence. Unfolding and translocation of the DHFR domain must be driven by the stroke of the signal-anchor sequence into translocon.  (+info)

Involvement of LuxR, a quorum sensing regulator in Vibrio harveyi, in the promotion of metabolic genes: argA, purM, lysE and rluA. (8/65)

Quorum sensing, involving signal transduction via the two-component response regulator LuxO to its downstream target LuxR, controls luminescence in the marine bacterium Vibrio harveyi. LuxR is a DNA binding protein that acts as both activator of the lux operon and repressor of its own gene. In order to determine if any other genes are affected by quorum sensing in V. harveyi, an assay for luxR-dependent promotion was devised using a genomic library maintained in a novel luxAB (luciferase) reporter. Screening in Escherichia coli DH-21 (lacI(sq)) entailed the addition of a second plasmid containing luxR under plac control. Four out of 5000 colonies showed luminescence stimulation upon IPTG induction of luxR. The four luxR-dependent promoters were upstream of argA, purM, lysE, and rluA, genes involved in arginine and purine biosyntheses, amino acid efflux, and pseudouridine synthesis, respectively. Based on analysis of luxR-dependent promoters, particularly that of argA, we describe a LuxR binding site, and implicate the coordination of LuxR with ArgR.  (+info)

We examined the distribution of NAGS and NAGK across the three domains of life. Although NAGK is found in archaea, eubacteria and eukaryotes, such as plants, algae and fungi, initially, we were only able to find sequences similar to either E. coli or mammalian NAGS in beta-proteobacteria, gamma-proteobacteria and three species of alpha-proteobacteria [48-50]. The three alpha-proteobacteria, M. maris, O. alexandrii and P. bermudensis, also appear to harbor acetylornithine transcarbamylase (argF) genes suggesting that their arginine biosynthesis pathway is similar to the one in X. campestris [7]. Identification of the alpha-proteobacterial NAGS genes that are closely related to the corresponding vertebrate, fungal and algal genes and to fungal NAGK is intriguing because mitochondria are thought to have arisen by endosymbiosis between proto-eukaryotic cell and an alpha-proteobacteria. Current thought suggests that the alpha-proteobacteria of the order Rickettsiales are the extant relatives of the ...
In the linear pathway (Figure 1A), GLU is converted to acetylglutamate (Ac-GLU) by N-acetylglutamate synthase (NAGS, encoded by argA) which is inhibited by ARG through negative feedback regulation [36],[39]. Sequential catalytic reactions catalyzed by the next three enzymes, N-acetylglutamate kinase (NAGK, encoded by argB), N-acetylglutamate semialdehyde dehydrogenase (encoded by argC) and N-acetylornithine transaminase (encoded by argD), which are common in the three pathways (Figure 1), yield N-acetylornithine (Ac-ORN) [34]. The next step, which distinguishes the linear pathway from the other two pathways, is deacetylation of Ac-ORN by AOase to yield ORN [40],[41]. The next and final steps are carried out by ornithine carbamoyltransferase (OTC or OTCase, encoded by argF), argininosuccinate synthase (encoded by argG) and argininosuccinate lyase (encoded by argH), which finally yield ARG [35]. This pathway has been found in a few species such as Myxococcus xanthus [41] and E. coli [36].. In many ...

Glutamate 5-kinase (G5K) makes the highly unstable product glutamyl 5-phosphate (G5P) in the initial, controlling step of proline/ornithine synthesis, being feedback-inhibited by proline or ornithine, and causing, when defective, clinical hyperammonaemia. We determined two crystal structures of G5K from Escherichia coli, at 2.9 A and 2.5 A resolution, complexed with glutamate and sulphate, or with G5P, sulphate and the proline analogue 5-oxoproline. E. coli G5K presents a novel tetrameric (dimer of dimers) architecture. Each subunit contains a 257 residue AAK domain, typical of acylphosphate-forming enzymes, with characteristic alpha(3)beta(8)alpha(4) sandwich topology. This domain is responsible for catalysis and proline inhibition, and has a crater on the beta sheet C-edge that hosts the active centre and bound 5-oxoproline. Each subunit contains a 93 residue C-terminal PUA domain, typical of RNA-modifying enzymes, which presents the characteristic beta(5)beta(4) sandwich fold and three alpha ...

In molecular biology, the amino acid kinase domain is a protein domain. It is found in protein kinases with various specificities, including the aspartate, glutamate and uridylate kinase families. In prokaryotes and plants the synthesis of the essential amino acids lysine and threonine is predominantly regulated by feed-back inhibition of aspartate kinase (AK) and dihydrodipicolinate synthase (DHPS). In Escherichia coli, thrA, metLM, and lysC encode aspartokinase isozymes that show feedback inhibition by threonine, methionine, and lysine, respectively. The lysine-sensitive isoenzyme of aspartate kinase from spinach leaves has a subunit composition of 4 large and 4 small subunits. In plants although the control of carbon fixation and nitrogen assimilation has been studied in detail, relatively little is known about the regulation of carbon and nitrogen flow into amino acids. The metabolic regulation of expression of an Arabidopsis thaliana aspartate kinase/homoserine dehydrogenase (AK/HSD) gene, ...

Thousand-and-one amino acid kinases (TAOK) 1 and 2 are activated catalytically during mitosis and can contribute to mitotic cell rounding and spindle positioning. Here, we characterize a compound that inhibits TAOK1 and TAOK2 activity with IC50 values of 11 to 15 nmol/L, is ATP-competitive, and targets these kinases selectively. TAOK inhibition or depletion in centrosome-amplified SKBR3 or BT549 breast cancer cell models increases the mitotic population, the percentages of mitotic cells displaying amplified centrosomes and multipolar spindles, induces cell death, and inhibits cell growth. In contrast, nontumorigenic and dividing bipolar MCF-10A breast cells appear less dependent on TAOK activity and can complete mitosis and proliferate in the presence of the TAOK inhibitor. We demonstrate that TAOK1 and TAOK2 localize to the cytoplasm and centrosomes respectively during mitosis. Live cell imaging shows that the TAOK inhibitor prolongs the duration of mitosis in SKBR3 cells, increases mitotic ...

ArgR may be the regulator of arginine biosynthesis genes in species. operon genes suggest that these genes are more tightly controlled. Other genes, including genes encoding regulatory proteins, possess a DNA sequence created by a single ARG-box which responds to ArgR, as validated by EMSA. Introduction Arginine metabolism is usually opinions repressed by arginine in different Gram-positive and Gram-negative bacteria. This effect is usually mediated by ArgR, a hexameric protein that represses arginine biosynthesis genes, using L-arginine as co-repressor, in and to locate ARG-boxes, for ArgR binding, upstream of several arginine biosynthesis genes [7]. This provided the basis to study arginine regulation in other species. This group of soil-dwelling bacteria produces many secondary metabolites that use arginine, or arginine-related molecules, as precursors. Streptomycin, mitomycin, streptothricin or clavulanic acid are metabolites that contain moieties of guanidine, carbamoyl groups, ornithine or ...

For analysis of covariance the residuals are obtained from an analysis of variance of both the response variable and the covariates. The residuals from the response variable are then regressed on the residuals from the covariates using, say, nag_regress_confid_interval (g02cbc) or nag_regsn_mult_linear (g02dac). The results from those functions can be used to test for the significance of the covariates. To test the significance of the treatment effects after fitting the covariate, the residual sum of squares from the regression should be compared with the residual sum of squares obtained from the equivalent regression but using the residuals from fitting blocks only ...
