Degradation of 1,2-dibromoethane by Mycobacterium sp. strain GP1. (1/50)

The newly isolated bacterial strain GP1 can utilize 1, 2-dibromoethane as the sole carbon and energy source. On the basis of 16S rRNA gene sequence analysis, the organism was identified as a member of the subgroup which contains the fast-growing mycobacteria. The first step in 1,2-dibromoethane metabolism is catalyzed by a hydrolytic haloalkane dehalogenase. The resulting 2-bromoethanol is rapidly converted to ethylene oxide by a haloalcohol dehalogenase, in this way preventing the accumulation of 2-bromoethanol and 2-bromoacetaldehyde as toxic intermediates. Ethylene oxide can serve as a growth substrate for strain GP1, but the pathway(s) by which it is further metabolized is still unclear. Strain GP1 can also utilize 1-chloropropane, 1-bromopropane, 2-bromoethanol, and 2-chloroethanol as growth substrates. 2-Chloroethanol and 2-bromoethanol are metabolized via ethylene oxide, which for both haloalcohols is a novel way to remove the halide without going through the corresponding acetaldehyde intermediate. The haloalkane dehalogenase gene was cloned and sequenced. The dehalogenase (DhaAf) encoded by this gene is identical to the haloalkane dehalogenase (DhaA) of Rhodococcus rhodochrous NCIMB 13064, except for three amino acid substitutions and a 14-amino-acid extension at the C terminus. Alignments of the complete dehalogenase gene region of strain GP1 with DNA sequences in different databases showed that a large part of a dhaA gene region, which is also present in R. rhodochrous NCIMB 13064, was fused to a fragment of a haloalcohol dehalogenase gene that was identical to the last 42 nucleotides of the hheB gene found in Corynebacterium sp. strain N-1074.  (+info)

Roles of horizontal gene transfer and gene integration in evolution of 1,3-dichloropropene- and 1,2-dibromoethane-degradative pathways. (2/50)

The haloalkane-degrading bacteria Rhodococcus rhodochrous NCIMB13064, Pseudomonas pavonaceae 170, and Mycobacterium sp. strain GP1 share a highly conserved haloalkane dehalogenase gene (dhaA). Here, we describe the extent of the conserved dhaA segments in these three phylogenetically distinct bacteria and an analysis of their flanking sequences. The dhaA gene of the 1-chlorobutane-degrading strain NCIMB13064 was found to reside within a 1-chlorobutane catabolic gene cluster, which also encodes a putative invertase (invA), a regulatory protein (dhaR), an alcohol dehydrogenase (adhA), and an aldehyde dehydrogenase (aldA). The latter two enzymes may catalyze the oxidative conversion of n-butanol, the hydrolytic product of 1-chlorobutane, to n-butyric acid, a growth substrate for many bacteria. The activity of the dhaR gene product was analyzed in Pseudomonas sp. strain GJ1, in which it appeared to function as a repressor of dhaA expression. The 1,2-dibromoethane-degrading strain GP1 contained a conserved DNA segment of 2.7 kb, which included dhaR, dhaA, and part of invA. A 12-nucleotide deletion in dhaR led to constitutive expression of dhaA in strain GP1, in contrast to the inducible expression of dhaA in strain NCIMB13064. The 1, 3-dichloropropene-degrading strain 170 possessed a conserved DNA segment of 1.3 kb harboring little more than the coding region of the dhaA gene. In strains 170 and GP1, a putative integrase gene was found next to the conserved dhaA segment, which suggests that integration events were responsible for the acquisition of these DNA segments. The data indicate that horizontal gene transfer and integrase-dependent gene acquisition were the key mechanisms for the evolution of catabolic pathways for the man-made chemicals 1, 3-dichloropropene and 1,2-dibromoethane.  (+info)

Enhanced metabolism of halogenated hydrocarbons in transgenic plants containing mammalian cytochrome P450 2E1. (3/50)

Chlorinated solvents, especially trichloroethylene (TCE), are the most widespread groundwater contaminants in the United States. Existing methods of pumping and treating are expensive and laborious. Phytoremediation, the use of plants for remediation of soil and groundwater pollution, is less expensive and has low maintenance; however, it requires large land areas and there are a limited number of suitable plants that are known to combine adaptation to a particular environment with efficient metabolism of the contaminant. In this work, we have engineered plants with a profound increase in metabolism of the most common contaminant, TCE, by introducing the mammalian cytochrome P450 2E1. This enzyme oxidizes a wide range of important pollutants, including TCE, ethylene dibromide, carbon tetrachloride, chloroform, and vinyl chloride. The transgenic plants had a dramatic enhancement in metabolism of TCE of up to 640-fold as compared with null vector control plants. The transgenic plants also showed an increased uptake and debromination of ethylene dibromide. Therefore, transgenic plants with this enzyme could be used for more efficient remediation of many sites contaminated with halogenated hydrocarbons.  (+info)

Paradoxical enhancement of the toxicity of 1,2-dibromoethane by O6-alkylguanine-DNA alkyltransferase. (4/50)

The presence of the DNA repair protein O(6)-alkylguanine-DNA alkyltransferase (AGT) paradoxically increases the mutagenicity and cytotoxicity of 1,2-dibromoethane (DBE) in Escherichia coli. This enhancement of genotoxicity did not occur when the inactive C145A mutant of human AGT (hAGT) was used. Also, hAGT did not enhance the genotoxicity of S-(2-haloethyl)glutathiones that mimic the reactive product of the reaction of DBE with glutathione, which is catalyzed by glutathione S-transferase. These experiments support a mechanism by which hAGT activates DBE. Studies in vitro showed a direct reaction between purified recombinant hAGT and DBE resulting in a loss of AGT repair activity and a formation of an hAGT-DBE conjugate at Cys(145). A 2-hydroxyethyl adduct was found by mass spectrometry to be present in the Gly(136)-Arg(147) peptide from tryptic digests of AGT reacted with DBE. Incubation of AGT with DBE and oligodeoxyribonucleotides led to the formation of covalent AGT-oligonucleotide complexes. These results indicate that DBE reacts at the active site of AGT to generate an S-(2-bromoethyl) intermediate, which forms a highly reactive half-mustard at Cys(145). In the presence of DNA, the DNA-binding function of AGT facilitates formation of DNA adducts. In the absence of DNA, the intermediate undergoes hydrolytic decomposition to form AGT-Cys(145)-SCH(2)CH(2)OH.  (+info)

Activation of dihaloalkanes by thiol-dependent mechanisms. (5/50)

Dihaloalkanes constitute an important group of chemicals because of their widespread use in industry and agriculture and their potential for causing toxicity and cancer. Chronic toxic effects are considered to depend upon bioactivation, either by oxidation or thiol conjugation. Considerable evidence links genotoxicity and cancer with glutathione conjugations reactions, and some aspects of the mechanisms have been clarified with 1,2-dihaloalkanes and dihalomethanes. Recently the DNA repair protein O6-alkylguanine transferase has been shown to produce cytotoxicity and genotoxicity by means of a thiol-dependent process with similarities to the glutathione reactions.  (+info)

Characterization of a mutagenic DNA adduct formed from 1,2-dibromoethane by O6-alkylguanine-DNA alkyltransferase. (6/50)

It has been proposed that the DNA repair protein O6-alkylguanine-DNA alkyltransferase increases the mutagenicity of 1,2-dibromoethane by reacting with it at its cysteine acceptor site to form a highly reactive half-mustard, which can then react with DNA (Liu, L., Pegg, A. E., Williams, K. M., and Guengerich, F. P. (2002) J. Biol. Chem. 277, 37920-37928). Incubation of Escherichia coli-expressed human alkyltransferase with 1,2-dibromoethane and single-stranded oligodeoxyribonucleotides led to the formation of covalent transferaseoligo complexes. The order of reaction determined was Gua>Thy>Cyt>Ade. Mass spectrometry analysis of the tryptic digest of the reaction product indicated that some of the adducts led to depurination with the release of the Gly136-Arg147 peptide cross-linked to a Gua at the N7 position, with the site of reaction being the active site Cys145 as established by chromatographic retention time and the fragmentation pattern determined by tandem mass spectrometry of a synthetic peptide adduct. The alkyltransferase-mediated mutations produced by 1,2-dibromoethane were predominantly Gua to Ade transitions but, in the spectrum of such rifampicin-resistant mutations in the RpoB gene, 20% were Gua to Thy transversions. The latter are likely to have arisen from the apurinic site generated from the Gua-N7 adduct. Support exists for an additional adduct/mutagenic pathway because evidence was obtained for DNA adducts other than at the Gua N7 atom and for mutations other than those attributable to depurination. Thus, chemical and biological evidence supports the existence of at least two alkyltransferase-dependent pathways for 1,2-dibromoethane-induced mutagenicity, one involving Gua N7-alkylation by alkyltransferase-S-CH2CH2Br and depurination, plus another as yet uncharacterized system(s).  (+info)

Mutation spectrum and sequence alkylation selectivity resulting from modification of bacteriophage M13mp18 DNA with S-(2-chloroethyl)glutathione. Evidence for a role of S-(2-N7-guanyl)ethyl)glutathione as a mutagenic lesion formed from ethylene dibromide. (7/50)

The major DNA adduct (greater than 95% total) resulting from the bioactivation of ethylene dibromide by conjugation with GSH is S-(2-(N7-guanyl)ethyl)GSH. The mutagenic potential of this adduct has been uncertain, however, because the observed mutagenicity might be caused by other adducts present at much lower levels, e.g. S-(2-N1-adenyl)ethyl)GSH. To assess the formation of other potential adducts, S-(2-(N3-deoxycytidyl)ethyl)GSH, S-(2-(O6-deoxyguanosyl)ethyl)GSH, and S-(2-(N2-deoxyguanosyl)ethyl)GSH were prepared and used as standards in the analysis of calf thymus DNA modified by treatment with [1,2-14C]ethylene dibromide and GSH in the presence of rat liver cytosol; only minor amounts (less than 0.2%) were found. A forward mutation assay in (repair-deficient) Salmonella typhimurium TA100 and sequence analysis were utilized to determine the type, site, and frequency of mutations in a portion of the lacZ gene resulting from in vitro modification of bacteriophage M13mp18 DNA with S-(2-chloroethyl)GSH, an analog of the ethylene dibromide-GSH conjugate. An adduct level of approximately 8 nmol (mg DNA)-1 resulted in a 10-fold increase in mutation frequency relative to the spontaneous level. The spectrum of spontaneous mutations was quite varied, but the spectrum of S-(2-chloroethyl)GSH-induced mutations consisted primarily of base substitutions of which G:C to A:T transitions accounted for 75% (70% of the total mutations). All available evidence implicates S-(2-(N7-guanyl)ethyl)GSH as the cause of these mutations inasmuch as the levels of the minor adducts are not consistent with the mutation frequency observed in this system. The sequence selectivity of alkylation was determined by treatment of end-labeled lac DNA fragments with S-(2-chloroethyl)GSH, cleavage of the DNA at adduct sites, and electrophoretic analysis. Comparison of the sequence selectivity with the mutation spectrum revealed no obligate relationship between the extent of adduct formation and the number of mutations which resulted at different sites. We suggest that the mechanism of mutagenesis involves DNA sequence-dependent alterations in the interaction of the polymerase with the (modified) template and incoming nucleotide.  (+info)

We report that men who do not have homozygous deletions at GSTT1 (i.e., whose GST-θ protein is presumably expressed and functional) are at increased CaP risk. Although our results are largely hypothesis generating, these findings are consistent with knowledge that GST-θ produces genotoxic metabolites in response to specific exposures (1, 2, 3) . There is substantial evidence that glutathione S conjugates derived from halogenated alkanes, halogenated alkenes, hydroquinones, quinones, aminophenols, and other compounds can cause cellular and DNA damage (reviewed in Ref. 10 ). Many of these compounds are commonly found as occupational exposures, and some are known carcinogens. Glutathione metabolic intermediates from ethylene dibromide, 1,2,3,4-diepoxybutane, methyl bromide, epibromohydrin, 1,3-dichloroacetone, and methylene chloride are mutagenic (1 , 2) . Epidemiological evidence has provided further support that these compounds may be involved in prostate carcinogenesis. For example, cellulose ...
Ah, Chemtrails. You see them, I see them, the planes responsible for them are clearly visible in a typical day, but according to military and governmental spokespeople, they simply are not there.. Unlike normal condensation trails, these trails do not dissipate after ten minutes or so.

The focus of our research is to investigate the structural basis for carcinogenic and anticancer activity of DNA- and protein-modifying agents. Synthetic methodologies are developed to prepare structurally modified nucleosides and amino acids representing carcinogen- and drug-induced DNA and protein adducts. The effects of nucleobase modifications on DNA structure and stability are determined by NMR spectroscopy, mass spectrometry, CD spectroscopy, and computer modeling of chemically altered DNA. Biological mass spectrometry techniques are employed to quantify the formation of DNA and protein adducts in vivo. These studies identify the molecular targets of exogenous and endogenous electrophiles and provide an insight into the origins of their biological activity. The following projects are currently underway:.

When I think of bad boys in romantic suspense I still think of all the same character traits but see a man that is more independent, follows his hunches and maybe does things in an unconventional manner that is no less effective than the rule followers. I see them as bounty hunters, private detectives, rogue or undercover FBI or DEA agents. Someone with an air of mystery that is comfortable making his own decisions without being ordered ...

Great Lakes Chemicals involvement in the bromine business -- the primary raw material used for methyl bromide production -- has its roots in leaded gasoline. When tetraethyl lead was invented as a gasoline additive back in the 1920s, it turned out that it left a corrosive byproduct in the engine. The solution that scientists found was to add a chemical called ethylene dibromide (EDB) to the mix.. As leaded gasoline began to be phased out and then banned in many countries, Great Lakes developed international markets for its deadly product. Indeed, today, the only remaining private sector corporation producing and marketing TEL is Great Lakes subsidiary, Associated Octel.[6] In fact, financial analysts estimate that in 1995, TEL accounted for nearly half of all Great Lakes profits.[7]. Meanwhile, the globalization of leaded gasoline has made TEL responsible for nearly 90 percent of airborne lead pollution in Third World cities today. Whats more, when burned, the EDB in leaded gasoline produces ...
A characteristic feature of the class Theta glutathione S-transferase (GST) T1-1 is its ability to activate dichloromethane and dibromoethane by catalysing the formation of mutagenic conjugates. The level of the GSTT1 subunit within tissues is an important determinant of susceptibility to the carcinogenic effects of these dihaloalkanes. In the present study it is demonstrated that hepatic GST activity towards these compounds can be elevated significantly in female and male Fischer-344 rats by feeding these animals on diets supplemented with cancer chemopreventive agents. Immunoblotting experiments showed that increased activity towards the dihaloalkanes is associated with elevated levels of the GSTT1 subunit in rat liver. Sex-specific effects were observed in the induction of GSTT1 protein. Amongst the chemopreventive agents tested, indole-3-carbinol proved to be the most potent inducer of hepatic GSTT1 in male rats (6.2-fold), whereas coumarin was the most potent inducer of this subunit in the ...
Several series of ligands, designed to chelate silver(I) specifically in the presence of base metals, have been synthesised. The ligands include: - dithiodiamide compounds, prepared by the condensation of acetanilide derivatives with 1,2-dibromoethane; propanenitrile and propanoic ester derivatives prepared from pyridine-2-carbaldehyde via the Morita-Baylis-Hillman reaction; and novel malonamide ligands from the reaction of diethyl malonate with a range of primary amines. The malonamide derivatives were prepared under both conventional thermal and microwave-assisted conditions, the latter proving to be highly efficient. The ligands were all characterised using a combination of spectroscopic and, where appropriate, elemental analysis; in one case, the structural assignment was confirmed by single-crystal X-ray analysis. The fragmentation patterns in the electron-impact mass spectra of the malonamide derivatives have been explored using high-resolution and meta-stable peak scanning ...
The other oxygenated quaternary center of 1 was constructed by O-alkylation of 7 with diazo malonate followed by methylation and reduction. Acetylation of the diol 8 proceeded with 10:1 diastereoselectivity, to give, after oxidation, the aldehyde 9.. In the first of a sequence of three intramolecular bond-forming reactions, HF.py cyclized the aldehyde onto the endocyclic alkene, and also freed the alcohol, that was alkylated with the dibromide 10 to give 11 as a 1.5:1 mixture of diastereomers. On exposure to SmI2, the major diastereomer cyclized to give a intermediate that was carried on to 1. The minor diastereomer was merely reduced, to a product that could be recycled to 11.. With 1 in hand, the stage was set for the second intramolecular cyclization. Even though 1 was predominantly in the lactol form, there was enough of an equilibrium concentration of aldehyde present for the SmI2-mediated cyclization to proceed smoothly to 2.. ...

The detection of significant levels of halogenated aliphatic contaminants in groundwater resources in the United States has spurred a considerable effort to understand the various mechanisms--both microbiological and abiotic--by which these compounds may be transformed. In aerobic environments, the abiotic reactions that predominate are elimination of hydrogen halide (dehydrohalogenation) and nucleophilic substitution by H2O (hydrolysis). Little research has examined the rates and pathways of abiotic reactions that may be significant under hypoxic conditions. The dehalogenation of 1,2-dichloroethane (1,2-DCA) and 1,2-dibromoethane (EDB) in phosphate buffer was examined alone, and in phosphate buffer containing hydrogen sulfide. Kinetic runs were conducted at pH 7 over the temperature range from 25 to 87.5 C. Phosphate buffer catalyzed the hydrolysis of both 1,2-SCA and EDB. This catalysis was attributed to the buffer anion HPO4(2-). The rate laws for these transformations exhibit the following ...
In the 1920s, a partially dug section of Love Canal, located in the southeast corner of Niagara Falls, New York, became a chemical and municipal disposal site for several chemical companies and the city of Niagara Falls (NYSDOH 1978). An unknown array and quantity of chemicals were buried on-site until the waste site was capped in 1953. Estimates of hazardous waste in this landfill range from 22,000 tons (19,954 tonnes) (U.S. EPA 1996) to 176,000 tons (159,632 tonnes) (Online Ethics Center 1999). In the late 1950s, homebuilding began adjacent to the Love Canal landfill, subsequently breaching the cap. By 1978, compounds identified at this site included: benzene, toluene, benzoic acid, lindane, trichloroethylene (TCE), dibromoethane, benzaldehydes, methyl chloride, carbon tetrachloride, and chloroform (NYSDOH 1978). The Occidental Chemical-Hyde Park (then Hooker Chemicals and Plastics) site, from 1953 to 1975, received approximately 80,000 tons (72,560 tonnes) of chemical waste (U.S. EPA and ...
Hypothesis:. Differences in the proteome concerning cell death pathways of glaucoma patients correspond to the differences in the mRNA expression of these patients.. Specific aims:. Characterization of the cellular proteome from human leukocytes of glaucoma patients compared to healthy controls and patients with Parkinsons disease.. Background:. Glaucoma is a worldwide leading cause of blindness. The key feature of this ocular neuropathy is characterized by an excavating optic nerve head. Loss of retinal ganglion cells is the final end point in blinding diseases of the optic nerve such as glaucoma. It is known that neuronal cell death in glaucoma occurs by an apoptotic mechanism. In earlier studies we could demonstrate that this cell death is reflected in circulating leukocytes by different parameters, like differential mRNA expression, and an increased fragmentation of the DNA. The differences in mRNA expression indicate a close relationship to cellular stress conditions and apoptotic events: ...
Recent in vitro studies indicate that neurons in the pre-Bötzinger (pre-Bot) complex of neonatal rats play an essential role in respiratory rhythm generation. In the adult rat, however, the location and physiology of pre-Bot neurons is less clearly understood. The present study aims to investigate the firing patterns of neurons that are located between Bötzinger and rVRG area, and the precise location of this transition zone in relation to other medullary nuclei. Sprague-Dawley rats (weighted between 400-550 g) were anaesthetised with 72 mg/kg sodium pentobarbitone and 0.4 mg/kg atropine (i.p.), and paralysed with 1 mg/kg pancuronium dibromide (i.v.), followed by additional doses as required. Extracellular recordings were made from 302 respiratory units located between 0 and 1.6 mm caudal to the facial nucleus and ventral to the nucleus ambiguus. As expected, expiratory units were mostly recorded from the rostral medulla (80%, 125/157) and inspiratory units were concentrated in the more caudal ...
