Oxidative polymerization of ribonuclease A by lignin peroxidase from Phanerochaete chrysosporium. Role of veratryl alcohol in polymer oxidation. (1/308)

The mechanism of lignin peroxidase (LiP) was examined using bovine pancreatic ribonuclease A (RNase) as a polymeric lignin model substrate. SDS/PAGE analysis demonstrates that an RNase dimer is the major product of the LiP-catalyzed oxidation of this protein. Fluorescence spectroscopy and amino acid analyses indicate that RNase dimer formation is due to the LiP-catalyzed oxidation of Tyr residues to Tyr radicals, followed by intermolecular radical coupling. The LiP-catalyzed polymerization of RNase in strictly dependent on the presence of veratryl alcohol (VA). In the presence of 100 microM H2O2, relatively low concentrations of RNase and VA, together but not individually, can protect LiP from H2O2 inactivation. The presence of RNase strongly inhibits VA oxidation to veratraldehyde by LiP; whereas the presence of VA does not inhibit RNase oxidation by LiP. Stopped-flow and rapid-scan spectroscopy demonstrate that the reduction of LiP compound I (LiPI) to the native enzyme by RNase occurs via two single-electron steps. At pH 3.0, the reduction of LiPI by RNase obeys second-order kinetics with a rate constant of 4.7 x 10(4) M-1.s-1, compared to the second-order VA oxidation rate constant of 3.7 x 10(5) M-1.s-1. The reduction of LiP compound II (LiPII) by RNase also follows second-order kinetics with a rate constant of 1.1 x 10(4) M-1.s-1, compared to the first-order rate constant for LiPII reduction by VA. When the reductions of LiPI and LiPIi are conducted in the presence of both VA and RNase, the rate constants are essentially identical to those obtained with VA alone. These results suggest that VA is oxidized by LiP to its cation radical which, while still in its binding site, oxidizes RNase.  (+info)

Growth of Azospirillum irakense KBC1 on the aryl beta-glucoside salicin requires either salA or salB. (2/308)

The rhizosphere nitrogen-fixing bacterium Azospirillum irakense KBC1 is able to grow on pectin and beta-glucosides such as cellobiose, arbutin, and salicin. Two adjacent genes, salA and salB, conferring beta-glucosidase activity to Escherichia coli, have been identified in a cosmid library of A. irakense DNA. The SalA and SalB enzymes preferentially hydrolyzed aryl beta-glucosides. A Delta(salA-salB) A. irakense mutant was not able to grow on salicin but could still utilize arbutin, cellobiose, and glucose for growth. This mutant could be complemented by either salA or salB, suggesting functional redundancy of these genes in salicin utilization. In contrast to this functional homology, the SalA and SalB proteins, members of family 3 of the glycosyl hydrolases, show a low degree of amino acid similarity. Unlike SalA, the SalB protein exhibits an atypical truncated C-terminal region. We propose that SalA and SalB are representatives of the AB and AB' subfamilies, respectively, in glycosyl hydrolase family 3. This is the first genetic implication of this beta-glucosidase family in the utilization of beta-glucosides for microbial growth.  (+info)

Catabolite control of Escherichia coli regulatory protein BglG activity by antagonistically acting phosphorylations. (3/308)

In bacteria various sugars are taken up and concomitantly phosphorylated by sugar-specific enzymes II (EII) of the phosphoenolpyruvate:sugar phosphotransferase system (PTS). The phosphoryl groups are donated by the phosphocarrier protein HPr. BglG, the positively acting regulatory protein of the Escherichia coli bgl (beta-glucoside utilization) operon, is known to be negatively regulated by reversible phosphorylation catalyzed by the membrane spanning beta-glucoside-specific EIIBgl. Here we present evidence that in addition BglG must be phosphorylated by HPr at a distinct site to gain activity. Our data suggest that this second, shortcut route of phosphorylation is used to monitor the state of the various PTS sugar availabilities in order to hierarchically tune expression of the bgl operon in a physiologically meaningful way. Thus, the PTS may represent a highly integrated signal transduction network in carbon catabolite control.  (+info)

In vitro studies on the initial reactions of anaerobic ethylbenzene mineralization. (4/308)

Anaerobic mineralization of ethylbenzene by the denitrifying bacterium Azoarcus sp. strain EB1 was recently shown to be initiated by dehydrogenation of ethylbenzene to 1-phenylethanol. 1-Phenylethanol is converted to benzoate (benzoyl coenzyme A) via acetophenone as transient intermediate. We developed in vitro assays to examine ethylbenzene dehydrogenase and 1-phenylethanol dehydrogenase activities in cell extracts of this strain. With p-benzoquinone as the electron acceptor, cell extracts of Azoarcus sp. strain EB1 catalyzed ethylbenzene oxidation at a specific rate of 10 nmol min(-1) [mg of protein](-1) and an apparent K(m) for ethylbenzene of approximately 60 microM. The membrane-associated ethylbenzene dehydrogenase activity was found to oxidize 4-fluoroethylbenzene and propylbenzene but was unable to transform 4-chloro-ethylbenzene, the ethyltoluenes, and styrene. Enzymatic ethylbenzene oxidation was stereospecific, with (S)-(-)-1-phenylethanol being the only enantiomer detected by chiral high-pressure liquid chromatography analysis. Moreover, cell extracts catalyzed the oxidation of (S)-(-)-1-phenylethanol but not of (R)-(+)-1-phenylethanol to acetophenone. When cell extracts were dialyzed, (S)-(-)-1-phenylethanol oxidation occurred only in the presence of NAD(+), suggesting that NAD(+) is the physiological electron acceptor of 1-phenylethanol dehydrogenase. Both ethylbenzene dehydrogenase and 1-phenylethanol dehydrogenase activities were present in Azoarcus sp. strain EB1 cells that were grown anaerobically on ethylbenzene, 1-phenylethanol, and acetophenone, but these activities were absent in benzoate-grown cells.  (+info)

Protective effect of FR168888, a new Na+/H+ exchange inhibitor, on ischemia and reperfusion-induced arrhythmia and myocardial infarction in rats: in comparison with other cardioprotective compounds. (5/308)

We have studied the effects of FR168888 (5-hydroxymethyl-3-(pyrrol-1-yl)benzoylguanidine methanesulfonate), a new Na+/H+ exchange inhibitor, on ischemia and reperfusion-induced arrhythmia and myocardial infarction in anesthetized rats and compared them with those of other cardioprotective compounds. FR168888 had a potent inhibitory effect on Na+/H+ exchange of rat lymphocytes acidified with Na+-propionate with a Ki value of 6.4 nM. Pretreatment with FR168888 (0.032-0.32 mg/kg, i.v.) reduced or completely abolished the ventricular fibrillation (VF) induced by reperfusion after 5 min of regional ischemia, while lidocaine, a class I antiarrhythmic agent, showed less effect against VF as compared with FR168888. The size of myocardial infarction induced by 60-min ischemia and 60-min reperfusion was attenuated by FR168888 dose-dependently (1.0-10 mg/kg, i.v.), and ventricular tachycardia and VF were significantly reduced during the ischemic period. In contrast, propranolol and diltiazem did not show such protective effects on myocardial infarct size. In addition, FR168888 did not change hemodynamic parameters in rats. These results indicate that FR168888 has a strong inhibitory effect on Na+/H+ exchange and that treatment with FR168888 can protect the heart from arrhythmia and myocardial cell death in ischemic and reperfused situations.  (+info)

Veratryl alcohol-mediated oxidation of isoeugenyl acetate by lignin peroxidase. (6/308)

The mechanism of the veratryl alcohol (VA)-mediated oxidation of isoeugenyl acetate (IEA) by lignin peroxidase, and the subsequent spontaneous Calpha-Cbeta cleavage of IEA to vanillyl acetate were studied. IEA oxidation only occurred in the presence of VA. It probably did not bind to lignin peroxidase as evidenced by an unaffected Km for VA in the presence of IEA, and by the fact that a 10-fold molar excess of the unreactive IEA counterpart, eugenyl acetate, did not affect the IEA oxidation rate. IEA was very efficient in recycling VA. Up to 34 mol of IEA were oxidized per mol VA. Formation of the predominant VA oxidation product, veratraldehyde, was postponed until IEA was almost completely oxidized. Together these findings suggest that IEA was oxidized by VA.+ rather than directly by lignin peroxidase. Thus, VA functioned as a redox mediator during IEA oxidation which is remarkable considering the high calculated ionization potential of 8.81 eV. Regardless of the presence of O2, approximately 2 mol of IEA were consumed per mol H2O2, which indicated that IEA was enzymatically oxidized by one electron to the putative radical cation (IEA.+). After formation of IEA.+, a series of O2-dependent chemical reactions were responsible for Calpha-Cbeta cleavage to the major oxidation product vanillyl acetate, as evidenced by the observation that an N2 atmosphere did not inhibit IEA oxidation, but almost completely inhibited vanillyl acetate formation. GC-MS analyses revealed that under an air atmosphere 1-(4'-acetoxy-3'-methoxyphenyl)-2-propanone, 1-(4'-acetoxy-3'-methoxyphenyl)-1-hydroxy-2-propanone, and 1-(4'-acetoxy-3'-methoxyphenyl)-2-hydroxy-1-propanone were also formed. Formation of the latter two was diminished under an N2 atmosphere.  (+info)

(Z)-3-hexenyl and trans-linalool 3,7-oxide beta-primeverosides isolated as aroma precursors from leaves of a green tea cultivar. (7/308)

6-O-beta-D-Xylopyranosyl-beta-D-glucopyranosides (beta-primeverosides) of (Z)-3-hexenol and trans-linalool 3,7-oxide were newly isolated from fresh leaves of a tea cultivar (Camellia sinensis var. sinensis cv. Yabukita). In addition, the already identified beta-primeverosides of benzyl alcohol, methyl salicylate, and trans-linalool 3,6-oxide from an oolong tea cultivar were isolated from the Yabukita cultivar. It was confirmed that all aglycones of the linalool oxide glycosides isolated here were of the optically active S-form by chiral GC after enzymatic hydrolysis with glycosidase.  (+info)

Combined effects of dissociable and undissociable local anesthetics upon ATP-induced firefly bioluminescence. (8/308)

Combined effects of two drugs present simultaneously are usually expressed as summation, synergism or potentiation, and antagonism. When the sum of the effects of each drug present separately equals the combined effect of the two drugs present simultaneously, the action is called additive or summation. However, the expected value of the sum of each effect of drugs present alone has not been well defined. In this report, the thearetical value of the expected sum of each effect of two inhibitors is given and a graphical method is presented to visualize summation, synergism, and antagonism. The inhibitory effects of a dissociable local anesthetic, tetracaine, and an undissociable local anesthetic, benzyl alcohol, upon a soluble firefly luminescent system were analyzed according to the above theory. The results clearly indicate that the action of these two classes of local anesthetics is pure additive or summation.  (+info)

The reaction of H2O2 with thioanisole and p-methoxythioanisole catalysed by lignin peroxidase from Phanerochaete chrysosporium has been studied spectrophotometrically under turnover and single turnover conditions with a stopped-flow apparatus. Pre-formed lignin peroxidase compounds I and II are each able to react with the sulphides to form a sulphide radical cation. The radical cation is then converted into the sulphoxide either by reaction with the medium or by reaction with compound II. This is the first report of a direct reaction between compound II and the substrate radical cation. With thioanisole, significant enantiomeric selectivity and high oxygen incorporation in the sulphoxide are obtained because compound II is preferentially reduced by the enzyme-bound thioanisole radical cation compared with the neutral substrate. By contrast, with p-methoxythioanisole, the data imply formation of an intermediate ternary complex comprising compound II, radical cation and neutral substrate, such ...
Veratraldehyde is an important chemical used in perfumery, agrochemical, and pharmaceutical industries. Current processes of manufacture of veratraldehyde use homogeneous catalysts, which make them highly polluting, creating problems of disposal of effluents and product purity. In the current work, veratraldehyde was synthesized from O-alkylation of vanillin with an environmentally benign reagent, dimethyl carbonate. A series of potassium loaded La2O3-MgO were prepared by the incipient wetness impregnation method, and their performance was evaluated vis-à-vis MgO, La2O3, La2O3-MgO, and a series of 1-4 wt % K/La2O3-MgO. All catalysts were characterized by different techniques, such as N2 adsorption/desorption, XRD, TGA-DSC, FT-IR, CO2-TPD, and SEM techniques. The effect of different loadings (1-4 wt %) of potassium on La2O3-MgO was studied, among which 2 wt % K/La2O3-MgO showed the best activity and selectivity due to high dispersion of potassium and high basicity in comparison with the rest. ...

The lignin peroxidase (LiP) catalyzed oxidation of pyrogallol red (PR) in the absence and presence of veratryl alcohol (3,4-dimethoxybenzyl alcohol, VA) was carried out in bis (2-ethylhexyl) sulfosuccinate sodium (AOT)/ polyoxyethylene lauryl ether (Brij30) reversed micelles to elucidate the role of VA. Results indicated that VA could accelerate the LiP catalyzed oxidation of PR, especially at low H2O2 concentrations. Unlike in bulk aqueous medium, the protection of LiP by VA in the present medium was relatively unsubstantial, even at high H2O2 concentrations. Analysis of data from a series of experiments showed that the enhancement of the PR oxidation caused by VA was mainly due to the indirect oxidation of PR by VA+∙ from the LiP catalyzed oxidation of VA. It was also found that at the same protector concentration (40 μM), VA (the physiological substrate of LiP) was less effective than PR (a phenolic compound) in protecting LiP from the H2O2 derived inactivation. This novel phenomenon ...

Benzyl alcohol and ethanol were found to exhibit an opposite effect on cold adaptation ofBacillus subtilis. The growth lag induced in bacteria by temperature shift-down was reduced in the presence of benzyl alcohol from 80 to 58 min, whereas ethanol prolonged this interval up to 102 min. In parallel, the physical state of the cytoplasmic membrane in intact bacteria was examined with the help of steady-state fluorescence anisotropy of diphenylhexatriene. Benzyl alcohol decreased the anisotropy as a consequence of membrane fluidization whereas ethanol increased its value, suggesting membrane rigidization. The correlation of growth and fluorescence data indicates that the control of membrane structure represents an important part of bacterial adaptation to cold.

0047] Unexpectedly, in these methods and processes, melt index parameters such as MI and HLMI of the olefin polymer can decrease as the amount of the alcohol compound added to the polymerization reactor system is increased. Also unexpectedly, molecular weight parameters such as Mw and Mz of the olefin polymer can increase as the amount of the alcohol compound added to the polymerization reactor system is increased. The alcohol compound can be added to the polymerization reactor system (e.g., into a polymerization reactor) alone, with a carrier, with the dual catalyst system, etc. The amount of the alcohol compound added to the reactor system is not particularly limited, so long as the amount of the alcohol compound added to the reactor system is sufficient to impact at least one of the MI, HLMI, Mw, and Mz of the olefin polymer as described herein, and does not adversely impact the catalyst activity or polymer production rate in a significant manner (e.g., 20%+ reduction in catalyst activity, ...
Deflazacort Oral Suspension contains benzyl alcohol and is not approved for use in pediatric patients less than 5 years of age. Serious adverse reactions including fatal reactions and "gasping syndrome" occurred in premature neonates and low birth weight infants in the neonatal intensive care unit who received drugs containing benzyl alcohol as a preservative. In these cases, benzyl alcohol dosages of 99 to 234 mg/kg/day produced high levels of benzyl alcohol and its metabolites in the blood and urine (blood levels of benzyl alcohol were 0.61 to 1.378 mmol/L). Additional adverse reactions included gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Preterm, low-birth weight infants may be more likely to develop these reactions because they may be less able to metabolize benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse ...

The enzyme that catalyses the hydroxylation of the methyl group of p-cresol was purified from Pseudomonas putida. It has mol.wt. 115000 and appears to contain two subunits of equal molecular weight. One subunit is a c-type cytochrome and the other is a flavoprotein. Reduction of the cytochrome occurred on addition of substrate. The same enzyme catalyses both p-cresol hydroxylation and the further oxidation of the product, 4-hydroxybenzyl alcohol. The stoicheiometry of acceptor reduced per molecule of substrate oxidized is that for two dehydrogenation reactions. The Km for p-cresol is 7.3 × 10(-6) M and that for 4-hydroxybenzyl alcohol is 47.6 × 10(-6) M. The enzyme, which is assayed with phenazine methosulphate as electron acceptor, was stimulated by particulate material, which probably contains the acceptor in vivo. ...

The identification of kinetic models for multiphase reaction systems is complex due to the simultaneous effect of chemical reactions and mass transfers. The extentbased incremental approach simplifies the modeling task by transforming the reaction system into variant states called vessel extents, one for each rate process. This transformation is carried out from the measured numbers of moles (or concentrations) and requires as many measured species as there are rate processes. Then, each vessel extent can be modeled individually, that is, independently of the other dynamic effects. This paper presents a modified version of the extent-based incremental approach that can be used to identify multiphase reaction systems in the presence of instantaneous equilibria. Different routes are possible depending on the number and type of measured species. The approach is illustrated via the simulated example of the oxidation of benzyl alcohol by hypochlorite in a batch reactor.. ...
When speciality chemicals are manufactured within the pharmaceutical industry, they are often produced in stirred batch/semi-batch reactors. A methodology was explored, to help with the development of continuous fixed-bed catalytic reactors for this sector. This was tested on two different types of model reactions: (a) In the first, the viability of producing tertiary amines via borrowing hydrogen was explored, and the reaction of morpholine and benzyl alcohol was studied, on Ru and Pt catalysts. This provided an opportunity for an early involvement in small-scale batch testing of catalysts, and then experiments were performed with the catalyst supported on granules in a packed bed (i.d. = 7 mm, length = 300 mm). Although it was shown that continuous processing is viable, and that high conversions (e.g. 73 to 98%, at 150 ºC) could be achieved, unfortunately further work was necessary to identify a more robust catalyst system, before moving on to pilot-scale trials. (b) In the second, the ...

Photoinitiated reactions in van der Waals complexes provide a means to examine reactive pathways from well-defined initial geometries. In recent work, we re-examined reactive pathways following resonant two-photon ionization (R2PI) of the chlorobenzene-ammonia (PhCl⋯NH3) dimer. The dimer cation radical reacts primarily via Cl atom loss, and additional channels corresponding to HCl and H atom loss were identified. The structure of the reactive complex was confirmed as an in-plane σ-type, and computational studies of the dimer cation radical potential energy landscape revealed two nearly isoenergetic arenium ion intermediates (or Wheland intermediates). The intermediate produced from ipso addition was not stable with respect to either Cl or HCl loss, and the relative branching observed in experiment was well reproduced by microcanonical transition state theory (TST) calculations. Here, we report experimental and computational studies of the related PhBr⋯NH3 dimer, examined for the first time. We

The inhibitors present in dilute acid-treated lignocellulosic hydrolysates would show great effect on the growth and product formation of microorganisms. To understand their inhibitory law and mechanism on oleaginous microorganism could help improving the efficiency of lignocellulose hydrolysis, detoxification, and lipid fermentation. The effects of four representative alcohol compounds present in lignocellulosic hydrolysates, including furfuryl alcohol, vanillyl alcohol, catechol, hydroquinone on the cell growth and lipid accumulation of Trichosporon fermentans were systematically investigated in this work. The toxicity of selected alcohol compounds was well related to their log P value except furfuryl alcohol, whose log P value was the minimum but with the highest toxicity to T. fermentans. The inhibition of all the alcohol compounds on the growth of T. fermentans was more serious than on the lipid synthesis. Also, the growth of T. fermentans was more sensitive to the variation of inoculum size,
The oxidative coupling of sp3 hybridized carbon atoms by photocatalysis is a valuable synthetic method as stoichiometric oxidation reagents can be avoided and dihydrogen is the only byproduct of the reaction. Cadmium sulfide, a readily available semiconductor, was used as a visible light heterogeneous photocatalyst for the oxidative coupling of benzyl alcohols and benzyl amines by irradiation with blue light. Depending on the structure of the starting material, good to excellent yields of homocoupling products were obtained as mixtures of diastereomers. Cross-coupling between benzyl alcohols and benzyl amines gave product mixtures, but was selective for the coupling of tetrahydroisoquinolines to nitromethane. The results demonstrate that CdS is a suitable visible light photocatalyst for oxidative bond formation under anaerobic conditions. ...

Sulfur/graphene catalyst was invented to be recyclable and impressive for selective oxidation of benzyl alcohol under simple reaction conditions.In this study, graphene oxide (GO) was prepared by a Hummers and Offman method. A one-step environmentally way is developed to prepare sulfur/reduced graphene. Sulfur/reduced graphene oxide (S/RGO) composite has been synthesized using a simple and low cost method with thiosulfate and graphene oxide (GO) as precursors. The powder was determined by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy images. After that, As-prepared sulfur graphene has been used for oxidation of benzyl alcohols to benzaldehyde. Acetonitrile has been used as solvent in the reaction. This composite were able to oxidation of benzyl alcohol to benzaldehyde with high efficiency (about 96%). This conversion has been demonstrated by gas chromatography equipped with mass spectroscopy. Substituted benzyl alcohols also can be oxidized by O2 to ...

Molecular dynamics simulation has been used to investigate the role of benzyl alcohol (BA) in the morphological control of the growth of TiO2 on carbon nanotubes (CNTs) by the consideration of two model systems. First, the interface between graphene and BA, where we found that the adsorption layer is dominated by molecules lying parallel to the surface confirming the hypothesis that the phenyl ring in BA is able to undergo π−π stacking with the CNT. Second, simulation of the interface between BA and the most stable surfaces of rutile and anatase revealed that the phenyl ring favors an orientation parallel to the (110) surface of rutile, while at anatase surfaces, particularly (100), the ring is generally orientated perpendicular to the surface. We therefore propose that the mechanism by which CNTs are found experimentally to selectively template rutile nanotubes is due to noncovalent functionalization by BA, which subsequently induces the nucleation of a rutile structure via the interaction ...
