Kinetic and inhibition studies on substrate channelling in the bifunctional enzyme catalysing C-terminal amidation. (1/31)

A series of experiments has been conducted to investigate the possibility that substrate channelling might occur in the bifunctional forms of enzymes carrying out C-terminal amidation, a post-translational modification essential to the biological activity of many neuropeptides. C-terminal amidation entails sequential action by peptidylglycine mono-oxygenase (PAM, EC 1.14.17.3) and peptidylamidoglycolate lyase (PGL, EC 4.3.2.5), with the mono-oxygenase catalysing conversion of a glycine-extended pro-peptide into the corresponding alpha-hydroxyglycine derivative, which is then converted by the lyase into amidated peptide plus glyoxylate. Since the mono-oxygenase and lyase reactions exhibit tandem reaction stereospecificities, channelling of the alpha-hydroxy intermediate might occur, as is the case for some other multifunctional enzymes. Selective inhibition of the mono-oxygenase domain by competitive ester inhibitors, as well as mechanism-based mono-oxygenase inactivation by the novel olefinic inhibitor 5-acetamido-4-oxo-6-phenylhex-2-enoate (N-acetylphenylalanyl acrylate), has little to no effect on the kinetic parameters of the lyase domain of the AE from Xenopus laevis. Similarly, inhibition of the lyase domain by the potent dioxo inhibitor 2,4-dioxo-5-acetamido-6-phenylhexanoate has little effect on the activity of the monooxygenase domain in the bifunctional enzyme. A series of experiments on intermediate accumulation and conversion were also carried out, along with kinetic investigations of the reactivities of the monofunctional and bifunctional forms of PAM and PGL towards substrates and inhibitors. Taken together, the results demonstrate the kinetic independence of the mono-oxygenase and lyase domains, and provide no evidence for substrate channelling between these domains in the bifunctional amidating enzyme.  (+info)

Kinetic and stereochemical studies on novel inactivators of C-terminal amidation. (2/31)

C-terminal amidation, a required post-translational modification for the bioactivation of many neuropeptides, entails sequential enzymic action by peptidylglycine alpha-mono-oxygenase (PAM, EC 1.14.17.3) and peptidylamidoglycolate lyase (PGL, EC 4.3.2.5). Here we introduce novel compounds in which an olefinic functionality is incorporated into peptide analogues as the most potent turnover-dependent inactivators of PAM. Kinetic parameters for PAM inactivation by 4-oxo-5-acetamido-6-phenyl-hex-2-enoic acid and 4-oxo-5-acetamido-6-(2-thienyl)-hex-2-enoic acid were obtained by using both the conventional dilution assay method and the more complex progress curve method. The results obtained from the progress curve method establish that these compounds exhibit the kinetic characteristics of pure competitive inactivators (i.e. no ESI complex forms during inactivation). On the basis of k(inact)/K(i) values, 4-oxo-5-acetamido-6-(2-thienyl)-hex-2-enoic acid is almost two orders of magnitude more potent than benzoylacrylate, a chemically analogous olefinic inactivator that lacks the peptide moiety. Stereochemical studies established that PAM inactivation by 4-oxo-5-acetamido-6-(2-thienyl)-hex-2-enoic acid is stereospecific with respect to the moiety at the P(2) position, which is consistent with previous results with substrates and reversible inhibitors. In contrast, 2, 4-dioxo-5-acetamido-6-phenylhexanoic acid, which is a competitive inhibitor with respect to ascorbate, exhibits a low degree of stereospecificity in binding to the ascorbate sites of both PAM and dopamine-beta-hydroxylase.  (+info)

Urea is a product of ureidoglycolate degradation in chickpea. Purification and characterization of the ureidoglycolate urea-lyase. (3/31)

A ureidoglycolate-degrading activity was analyzed in different organs of chickpea (Cicer arietinum). Activity was detected in all the tissues analyzed, but highest levels of specific activity were found in pods, from which it has been purified and characterized. This is the first ureidoglycolate-degrading activity that has been purified to homogeneity from any photosynthetic organism. Only one ureidoglycolate-degrading activity was found during the purification. The enzyme was purified 1,500-fold, and specific activity for the pure enzyme was 8.6 units mg(-1), which corresponds with a turnover number of 1,600 min(-1). The native enzyme has a molecular mass of 180 kD and consists of six identical or similar-sized subunits of 31 kD each. The enzyme exhibited hyperbolic, Michaelian kinetics for (-) ureidoglycolate with K(m) values of 6 and 10 microM in the presence or absence of Mn(2+), respectively. Optimum pH was between 7 and 8 and maximum activity was found at temperatures above 70 degrees C, the enzyme being extremely stable and resistant to heat denaturation. The activity was inhibited by EDTA and enhanced by several bivalent cations, thus suggesting that the enzyme is a metalloprotein. This enzyme has been characterized as a ureidoglycolate urea-lyase (EC 4.3.2.3), which catalyzes the degradation of (-) ureidoglycolate to glyoxylate and urea. This is the first time that such an activity is detected in plant tissues. A possible function for this activity and its implications in the context of nitrogen mobilization in legume plants is also discussed.  (+info)

Pathways for urea production during early life of an air-breathing teleost, the African catfish Clarias gariepinus Burchell. (4/31)

Embryos and larvae of the African catfish Clarias gariepinus excrete significant quantities of urea. The present study focused on the potential urea-generating pathways during early development of this teleost; uricolysis, argininolysis and the ornithine-urea cycle (OUC). Uricase, allantoinase, allantoicase and ureidoglycollate lyase of the uricolytic pathway were expressed in all early life stages and in adult liver of C. gariepinus. Uricase activity increased in starved larvae compared with yolk-sac larvae. The key regulatory enzyme of the teleost OUC, carbamoyl phosphate synthetase III (CPSase III), was expressed predominantly in muscle of developing C. gariepinus larvae and showed negligible activity in the absence of its allosteric effector N-acetyl-L-glutamate. CPSase III and ornithine carbamoyl transferase activities increased in fed larvae compared with starved larvae. In contrast to the early developmental stages, adult C. gariepinus expressed only low and variable levels of CPSase III, suggesting that, under the experimental conditions employed, OUC expression is influenced by developmental stage in this species. The data indicate that early C. gariepinus life stages express the enzymes necessary for urea production by uricolysis, argininolysis and the OUC, and this may explain why urea tissue levels and urea excretion rates are substantial during the early development of this air-breathing teleost.  (+info)

Catalysis, stereochemistry, and inhibition of ureidoglycolate lyase. (5/31)

Ureidoglycolate lyase (UGL, EC 4.3.2.3) catalyzes the breakdown of ureidoglycolate to glyoxylate and urea, which is the final step in the catabolic pathway leading from purines to urea. Although the sequence of enzymatic steps was worked out nearly 40 years ago, the stereochemistry of the uric acid degradation pathway and the catalytic properties of UGL have remained very poorly described. We now report the first direct investigation of the absolute stereochemistry of UGL catalysis. Using chiral chromatographic analyses with substrate enantiomers, we demonstrate that UGL catalysis is stereospecific for substrates with the (S)-hydroxyglycine configuration. The first potent competitive inhibitors for UGL are reported here. These inhibitors are compounds which contain a 2,4-dioxocarboxylate moiety, designed to mimic transient species produced during lyase catalysis. The most potent inhibitor, 2,4-dioxo-4-phenylbutanoic acid, exhibits a KI value of 2.2 nM and is therefore among the most potent competitive inhibitors ever reported for a lyase enzyme. New synthetic alternate substrates for UGL, which are acyl-alpha-hydroxyglycine compounds, are described. Based on these alternate substrates, we introduce the first assay method for monitoring UGL activity directly. Finally, we report the first putative primary nucleotide and derived peptide sequence for UGL. This sequence exhibits a high level of similarity to the fumarylacetoacetate hydrolase family of proteins. Close mechanistic similarities can be visualized between the chemistries of ureidoglycolate lyase and fumarylacetoacetate hydrolase catalysis.  (+info)

Differentially regulated malate synthase genes participate in carbon and nitrogen metabolism of S. cerevisiae. (6/31)

We have isolated a second gene (MLS1), which in addition to DAL7, encodes malate synthase from S. cerevisiae. Expression of the two genes is specific for their physiological roles in carbon and nitrogen metabolism. Expression of MLS1, which participates in the utilization of non-fermentable carbon sources, is sensitive to carbon catabolite repression, but nearly insensitive to nitrogen catabolite repression. DAL7, which participates in catabolism of the nitrogenous compound allantoin, is insensitive to carbon catabolite repression, but highly sensitive to nitrogen catabolite repression. Results obtained with null mutations in these genes suggest that S. cerevisiae contains at least one and perhaps two additional malate synthase genes.  (+info)

The source of the oxygen atom in the alpha-hydroxyglycine intermediate of the peptidylglycine alpha-amidating reaction. (7/31)

Peptidylglycine alpha-amidating activity catalyses the oxidation of a C-terminally glycine-extended peptide to a desglycine alpha-amidated peptide at the expense of ascorbate and O2 in the presence of Cu2+. The reaction involves oxidative N-dealkylation within the terminal glycine residue, with retention of the glycine N atom and release of the remainder as glyoxylate. Recent studies by us and others have revealed that the reaction consists of two steps via a carbinolamide as an intermediate (peptidyl alpha-hydroxyglycine), and also that two separate enzymes derived from a common precursor protein catalyse these steps, formation of the carbinolamide and its conversion into alpha-amide and glyoxylate. As for the mechanism of carbinolamide formation, two distinct pathways can be considered: direct mono-oxygenation at the glycine alpha-C atom and dehydrogenation leading to an imine followed by hydration. To draw a distinction between them, we carried out the reaction with D-Tyr-Val-Gly as the substrate either in the H2(18)O-enriched medium or under an atmosphere of 18O2, and isolated the alpha-hydroxylglycine intermediate. The fast-atom-bombardment mass-spectral analysis demonstrated that the hydroxy O atom comes from O2, but not from H2O, indicating that the alpha-hydroxylation should be a monooxygenase reaction.  (+info)

Orteronel (racemic) is a mixture of S-Orteronel and R-Orteronel isomers. Orteronel, aslo known as TAK-700, is an orally bioavailable non-steroidal androgen synthesis inhibitor of steroid 17alpha-monooxygenase (17,20 lyase) with potential antiandrogen activity. TAK-700 binds to and inhibits the steroid 17alpha-monooxygenase in both the testes and adrenal glands, thereby inhibiting androgen production. This may decrease androgen-dependent growth signaling and may inhibit cell proliferation of androgen-dependent tumor cells.

STRASBOURG, FRANCE. Obesity is a growing problem among adolescents and is often accompanied by metabolic syndrome (MS). Metabolic syndrome involves a cluster of several metabolic abnormalities including overweight (specifically abdominal adiposity), insulin resistance, high triglycerides and low HDL (high-density lipoprotein) levels, and is associated with an increased risk of cardiovascular disease.. Researchers at the Louis Pasteur University of Strasbourg now report that overweight adolescents and overweight adolescents with MS exhibit significant differences in the fatty acid content of plasma phospholipids when compared to their non-overweight peers. Their study involved 60 12-year-olds (30 boys and 30 girls) with normal weight and 60 12-year-olds who were overweight. Twenty-five per cent of the overweight children had been diagnosed with MS as well (none of the normal weight children had MS). Analyses of the phospholipid phase of the blood plasma revealed several important differences ...
The posttranslational processing enzyme peptidylglycine alpha-amidating monooxygenase (PAM) occurs naturally in integral membrane and soluble forms. With the goal of understanding the targeting of these proteins to secretory granules, we have compared the maturation, processing, secretion, and storage of PAM proteins in stably transfected AtT-20 cells. Integral membrane and soluble PAM proteins exit the ER and reach the Golgi apparatus with similar kinetics. Biosynthetic labeling experiments demonstrated that soluble PAM proteins were endoproteolytically processed to a greater extent than integral membrane PAM; this processing occurred in the regulated secretory pathway and was blocked by incubation of cells at 20 degrees C. 16 h after a biosynthetic pulse, a larger proportion of soluble PAM proteins remained cell-associated compared with integral membrane PAM, suggesting that soluble PAM proteins were more efficiently targeted to storage granules. The nonstimulated secretion of soluble PAM ...

1] Volcanic eruptions are often accompanied by spatiotemporal migration of ground deformation, a consequence of pressure changes within magma reservoirs and pathways. We modeled the propagation of pressure variations through the east rift zone (ERZ) of K̄lauea Volcano, Hawaii, caused by magma withdrawal during the early eruptive episodes (1983-1985) of the ongoing Puu Ōō-Kupaianaha eruption. Eruptive activity at the Puu Ōō vent was typically accompanied by abrupt deflation that lasted for several hours and was followed by a sudden onset of gradual inflation once the eruptive episode had ended. Similar patterns of deflation and inflation were recorded at K̄laueas summit, approximately 15 km to the northwest, albeit with time delays of hours. These delay times can be reproduced by modeling the spatiotemporal changes in magma pressure and flow rate within an elastic-walled dike that traverses K̄laueas ERZ. Key parameters that affect the behavior of the magma-dike system are the dike ...

Drugs that inhibit rate-limiting enzymes have important uses as experimental tools and therapeutic agents. The findings presented here demonstrate that PBA inhibits circulating and tissue PHM and thus offers a pharmacological approach for investigating the regulation and function of this rate-limiting enzyme. Although significant advances have been made in our understanding of PHM in neural and endocrine tissues, virtually nothing is known about the physiology of blood-borne PHM, the form most profoundly inhibited by PBA treatment. Thus, PBA may prove to be especially useful in defining the functions of circulating PHM, in addition to increasing our understanding of PHM in peptidergic tissues.. Although the functions of blood-borne PHM remain to be determined, levels of circulating PHM are significant (Eipper et al., 1985; Wand et al., 1985; Ogonowski et al., 1997), and, as shown here, its turnover appears to be rapid. Several α-amidated peptides have been implicated in the control of ...

O Magma Crawler é provavelmente uma forma de vida produzida artificialmente. A sua agressividade puramente irracional comparada à óbvia estratégia de desenvolvimento do Magma Crawler leva à única conclusão, que eles são uma arma biológica muito difícil de controlar. É correto presumir que eles têm origem nas baias de reprodução do que os gnomos chamam de "aqueles embaixo". Se esse for o caso, eles foram criados para guerra e destruição. Eles foram provavelmente criados para causar o máximo de danos aos ambientes subterrâneos. Depois que um Magma Crawler é solto, eles são geralmente abandonados. Isso explica porque espécies errantes podem ser encontradas em quase todos os lugares subterrâneos, geralmente no fim de um caminho de destruição. Como até agora só foram encontrados Magma Crawlers machos, supõe-se que as criaturas fêmeas são retidas somente para reprodução e também para prevenir que a raça se espalhe excessivamente.

Will the Yellowstone magma chamber--make that chambers--ever stop growing? Well, theyre not actually growing per se; rather, scientists are discovering that Yellowstones magma chambers are bigger--and more numerous--than previously believed. In 2013, the upper magma chamber was revealed to be more than double its previously estimated volume. Then, this month, geophysicists announced the existence of an additional, deeper, larger magma reservoir sitting between the upper chamber and the mantle plume feeding the legendary volcano. Check out the video below, by the University of Utah, to see a 3D animation of the setup. You can read more about Yellowstone eruptions in my previous post, which has been updated. Read more → ...

Supereruptions violently transfer huge amounts (100 s-1000 s km3) of magma to the surface in a matter of days and testify to the existence of giant pools of magma at depth. The longevity of these giant magma bodies is of significant scientific and societal interest. Radiometric data on whole rocks, glasses, feldspar and zircon crystals have been used to suggest that the Bishop Tuff giant magma body, which erupted ∼760,000 years ago and created the Long Valley caldera (California), was long-lived (|100,000 years) and evolved rather slowly. In this work, we present four lines of evidence to constrain the timescales of crystallization of the Bishop magma body: (1) quartz residence times based on diffusional relaxation of Ti profiles, (2) quartz residence times based on the kinetics of faceting of melt inclusions, (3) quartz and feldspar crystallization times derived using quartz+feldspar crystal size distributions, and (4) timescales of cooling and crystallization based on thermodynamic and heat flow
3UGL: Structural and Functional Characterization of an Anesthetic Binding Site in the Second Cysteine-Rich Domain of Protein Kinase Cdelta
Most magmas only entirely melt for small parts of their histories. More typically, they are mixes of melt and crystals, and sometimes also of gas bubbles. Melt, crystals, and bubbles usually have different densities, and so they can separate as magmas evolve. As magma cools, minerals typically crystallize from the melt at different temperatures (fractional crystallization). As minerals crystallize, the composition of the residual melt typically changes. If crystals separate from the melt, then the residual melt will differ in composition from the parent magma. For instance, a magma of gabbroic composition can produce a residual melt of granitic composition if early formed crystals are separated from the magma. Gabbro may have a liquidus temperature near 1,200 °C, and the derivative granite-composition melt may have a liquidus temperature as low as about 700 °C. Incompatible elements are concentrated in the last residues of magma during fractional crystallization and in the first melts produced ...

m6A and m4C methyltransferases are found primarily in prokaryotes (although recent evidence has suggested that m6A is abundant in eukaryotes[1]). m5C methyltransfereases are found in some lower eukaryotes, in most higher plants, and in animals beginning with the echinoderms. The m6A methyltransferases (N-6 adenine-specific DNA methylase) (A-Mtase) are enzymes that specifically methylate the amino group at the C-6 position of adenines in DNA. They are found in the three existing types of bacterial restriction-modification systems (in type I system the A-Mtase is the product of the hsdM gene, and in type III it is the product of the mod gene). These enzymes are responsible for the methylation of specific DNA sequences in order to prevent the host from digesting its own genome via its restriction enzymes. These methylases have the same sequence specificity as their corresponding restriction enzymes. These enzymes contain a conserved motif Asp/Asn-Pro-Pro-Tyr/Phe in their N-terminal section, this ...
