Antisense RNA strategies for metabolic engineering of Clostridium acetobutylicum. (1/3961)

We examined the effectiveness of antisense RNA (as RNA) strategies for metabolic engineering of Clostridium acetobutylicum. Strain ATCC 824(pRD4) was developed to produce a 102-nucleotide asRNA with 87% complementarity to the butyrate kinase (BK) gene. Strain ATCC 824(pRD4) exhibited 85 to 90% lower BK and acetate kinase specific activities than the control strain. Strain ATCC 824(pRD4) also exhibited 45 to 50% lower phosphotransbutyrylase (PTB) and phosphotransacetylase specific activities than the control strain. This strain exhibited earlier induction of solventogenesis, which resulted in 50 and 35% higher final concentrations of acetone and butanol, respectively, than the concentrations in the control. Strain ATCC 824(pRD1) was developed to putatively produce a 698-nucleotide asRNA with 96% complementarity to the PTB gene. Strain ATCC 824(pRD1) exhibited 70 and 80% lower PTB and BK activities, respectively, than the control exhibited. It also exhibited 300% higher levels of a lactate dehydrogenase activity than the control exhibited. The growth yields of ATCC 824(pRD1) were 28% less than the growth yields of the control. While the levels of acids were not affected in ATCC 824(pRD1) fermentations, the acetone and butanol concentrations were 96 and 75% lower, respectively, than the concentrations in the control fermentations. The lower level of solvent production by ATCC 824(pRD1) was compensated for by approximately 100-fold higher levels of lactate production. The lack of any significant impact on butyrate formation fluxes by the lower PTB and BK levels suggests that butyrate formation fluxes are not controlled by the levels of the butyrate formation enzymes.  (+info)

Enhanced bioaccumulation of heavy metal ions by bacterial cells due to surface display of short metal binding peptides. (2/3961)

Metal binding peptides of sequences Gly-His-His-Pro-His-Gly (named HP) and Gly-Cys-Gly-Cys-Pro-Cys-Gly-Cys-Gly (named CP) were genetically engineered into LamB protein and expressed in Escherichia coli. The Cd2+-to-HP and Cd2+-to-CP stoichiometries of peptides were 1:1 and 3:1, respectively. Hybrid LamB proteins were found to be properly folded in the outer membrane of E. coli. Isolated cell envelopes of E. coli bearing newly added metal binding peptides showed an up to 1.8-fold increase in Cd2+ binding capacity. The bioaccumulation of Cd2+, Cu2+, and Zn2+ by E. coli was evaluated. Surface display of CP multiplied the ability of E. coli to bind Cd2+ from growth medium fourfold. Display of HP peptide did not contribute to an increase in the accumulation of Cu2+ and Zn2+. However, Cu2+ ceased contribution of HP for Cd2+ accumulation, probably due to the strong binding of Cu2+ to HP. Thus, considering the cooperation of cell structures with inserted peptides, the relative affinities of metal binding peptide and, for example, the cell wall to metal ion should be taken into account in the rational design of peptide sequences possessing specificity for a particular metal.  (+info)

Metabolic engineering of a 1,2-propanediol pathway in Escherichia coli. (3/3961)

1,2-Propanediol (1,2-PD) is a major commodity chemical that is currently derived from propylene, a nonrenewable resource. A goal of our research is to develop fermentation routes to 1,2-PD from renewable resources. Here we report the production of enantiomerically pure R-1,2-PD from glucose in Escherichia coli expressing NADH-linked glycerol dehydrogenase genes (E. coli gldA or Klebsiella pneumoniae dhaD). We also show that E. coli overexpressing the E. coli methylglyoxal synthase gene (mgs) produced 1,2-PD. The expression of either glycerol dehydrogenase or methylglyoxal synthase resulted in the anaerobic production of approximately 0.25 g of 1,2-PD per liter. R-1,2-PD production was further improved to 0.7 g of 1,2-PD per liter when methylglyoxal synthase and glycerol dehydrogenase (gldA) were coexpressed. In vitro studies indicated that the route to R-1,2-PD involved the reduction of methylglyoxal to R-lactaldehyde by the recombinant glycerol dehydrogenase and the reduction of R-lactaldehyde to R-1, 2-PD by a native E. coli activity. We expect that R-1,2-PD production can be significantly improved through further metabolic and bioprocess engineering.  (+info)

Multiple genetic modifications of the erythromycin polyketide synthase to produce a library of novel "unnatural" natural products. (4/3961)

The structures of complex polyketide natural products, such as erythromycin, are programmed by multifunctional polyketide synthases (PKSs) that contain modular arrangements of functional domains. The colinearity between the activities of modular PKS domains and structure of the polyketide product portends the generation of novel organic compounds-"unnatural" natural products-by genetic manipulation. We have engineered the erythromycin polyketide synthase genes to effect combinatorial alterations of catalytic activities in the biosynthetic pathway, generating a library of >50 macrolides that would be impractical to produce by chemical methods. The library includes examples of analogs with one, two, and three altered carbon centers of the polyketide products. The manipulation of multiple biosynthetic steps in a PKS is an important milestone toward the goal of producing large libraries of unnatural natural products for biological and pharmaceutical applications.  (+info)

E-CELL: software environment for whole-cell simulation. (5/3961)

MOTIVATION: Genome sequencing projects and further systematic functional analyses of complete gene sets are producing an unprecedented mass of molecular information for a wide range of model organisms. This provides us with a detailed account of the cell with which we may begin to build models for simulating intracellular molecular processes to predict the dynamic behavior of living cells. Previous work in biochemical and genetic simulation has isolated well-characterized pathways for detailed analysis, but methods for building integrative models of the cell that incorporate gene regulation, metabolism and signaling have not been established. We, therefore, were motivated to develop a software environment for building such integrative models based on gene sets, and running simulations to conduct experiments in silico. RESULTS: E-CELL, a modeling and simulation environment for biochemical and genetic processes, has been developed. The E-CELL system allows a user to define functions of proteins, protein-protein interactions, protein-DNA interactions, regulation of gene expression and other features of cellular metabolism, as a set of reaction rules. E-CELL simulates cell behavior by numerically integrating the differential equations described implicitly in these reaction rules. The user can observe, through a computer display, dynamic changes in concentrations of proteins, protein complexes and other chemical compounds in the cell. Using this software, we constructed a model of a hypothetical cell with only 127 genes sufficient for transcription, translation, energy production and phospholipid synthesis. Most of the genes are taken from Mycoplasma genitalium, the organism having the smallest known chromosome, whose complete 580 kb genome sequence was determined at TIGR in 1995. We discuss future applications of the E-CELL system with special respect to genome engineering. AVAILABILITY: The E-CELL software is available upon request. SUPPLEMENTARY INFORMATION: The complete list of rules of the developed cell model with kinetic parameters can be obtained via our web site at:  (+info)

Chimeric viruses incorporating the proteins of two JE strains, SA14-14-2 (human vaccine strain) and JE Nakayama (JE-N [virulent mouse brain-passaged strain]), were studied in cell culture and laboratory mice. The JE envelope protein (E) retained antigenic and biological properties when expressed with its prM protein together with the YF capsid; however, viable chimeric viruses incorporating the entire JE structural region (C-prM-E) could not be obtained. YF/JE(prM-E) chimeric viruses grew efficiently in cells of vertebrate or mosquito origin compared to the parental viruses. The YF/JE SA14-14-2 virus was unable to kill young adult mice by intracerebral challenge, even at doses of 10(6) PFU. In contrast, the YF/JE-N virus was neurovirulent, but the phenotype resembled parental YF virus rather than JE-N. Ten predicted amino acid differences distinguish the JE E proteins of the two chimeric viruses, therefore implicating one or more residues as virus-specific determinants of mouse neurovirulence in this chimeric system. This study indicates the feasibility of expressing protective antigens of JE virus in the context of a live, attenuated flavivirus vaccine strain (YF17D) and also establishes a genetic system for investigating the molecular basis for neurovirulence determinants encoded within the JE E protein.  (+info)

A small catalytic RNA motif with Diels-Alderase activity. (7/3961)

BACKGROUND: The 'RNA world' hypothesis requires that RNA be able to catalyze a wide variety of chemical reactions. In vitro selection from combinatorial RNA libraries has been used to identify several catalytic activities, most of which have resulted in a self-modification of RNA at one of its constituents. The formation of carbon-carbon bonds is considered an essential prerequisite for a complex metabolism based on RNA. RESULTS: We describe the selection and characterization of new ribozymes that catalyze carbon-carbon bond formation by Diels-Alder reaction of a biotinylated maleimide with an RNA-tethered anthracene. Secondary structure analysis identified a 49-nucleotide RNA motif that accelerates the reaction about 20,000-fold. The motif has only 11 conserved nucleotides that are present in most of the selected sequences. The ribozyme motif is remarkably adaptable with respect to cofactor and metal-ion requirements. The motif was also re-engineered to give a 38-mer RNA that can act as a 'true' catalyst on short external substrate oligonucleotide-anthracene conjugates. CONCLUSIONS: We have identified a small, highly abundant RNA motif that can solve the complex task of forming two carbon-carbon bonds between two reactants in trans, a catalytic capacity useful for creating prebiotically relevant molecules. This is the smallest and fastest RNA catalyst for carbon-carbon bond formation reported to date.  (+info)

Heterologous expression of alkene monooxygenase from Rhodococcus rhodochrous B-276. (8/3961)

Alkene monooxygenase (AMO) from Rhodococcus rhodochrous (formerly Nocardia corallina) B-276 is a three-component enzyme system encoded by the four-gene operon amoABCD. AMO catalyses the stereoselective epoxygenation of aliphatic alkenes, yielding primarily R enantiomers. The presumed site of alkene oxygenation is a dinuclear iron centre similar to that in the soluble methane monooxygenases of methanotrophic bacteria, to which AMO exhibits a significant degree of amino acid sequence identity. The AMO complex was not expressed in Escherichia coli, at least partly because that host did not produce all of the AMO polypeptides. Expression of AMO was achieved in Streptomyces lividans by cloning the AMO genes into the thiostrepton-inducible expression plasmid pIJ6021. No background of AMO activity was detected in S. lividans cells without amoABCD and expression of AMO activity, at a level comparable to that from wild-type R. rhodochrous B-276, coincided with appearance of the AMO subunits. Recombinant AMO activity in cell-free extracts of S. lividans was stimulated by the addition of NADH and produced R-epoxypropane with comparable enantiomeric excess to AMO purified from the original organism. Although the whole AMO complex could not be expressed in E. coli, the functional coupling protein (AmoB) and reductase (AmoD) were expressed individually in E. coli as fusions with glutathione S-transferase. The expression systems described here now allow structure/function studies on AMO to be carried out by site-directed mutagenesis.  (+info)

Define genetic engineering. genetic engineering synonyms, genetic engineering pronunciation, genetic engineering translation, English dictionary definition of genetic engineering. n. Scientific alteration of the structure of genetic material in a living organism. It involves the production and use of recombinant DNA and has been...
Genetic engineering, also called genetic modification, is the direct manipulation of an organisms genome using biotechnology. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism. Genes may be removed, or knocked out, using a nuclease. Gene targeting is a different technique that uses homologous recombination to change an endogenous gene, and can be used to delete a gene, remove exons, add a gene, or introduce point mutations.. An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO). The first GMOs were bacteria in 1973; GM mice were generated in 1974. Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994.. Genetic engineering techniques have been applied in numerous fields including ...

The Test Panel is based on the debugging support panel tool provided at the operator station of a CENTUM-XL. Even with this debugging tool, engineers still had to prepare as many operation and monitoring panels as needed for efficient debugging of process controls in the inspection phase of a DCS application. At present, the CENTUM CS has become the mainstay. Accordingly, in consideration of a successor to the CENTUM-XL tool, the differences in the platforms, and the use of standard CENTUM CS panels (graphic panels), we have developed a brand-new engineering tool for the CENTUM CS which allows the automatic generation of panels for debugging in order to increase engineering efficiency. This tool is the Test Panel. In addition, the standard features of a CENTUM CS system include, besides the ability to generate databases (i.e., various system builders), functions to test a DCS application generated with such engineering tools as the I/O List tool and EXSA module, allowing engineers to conduct ...
Introduction. Benefits and Restraints of Genetic Engineering and the Use of Recombinant DNA Genetic engineering and recombinant DNA have many useful purposes which benefit humans in many different ways in many different fields. The latest bio-technological breakthroughs allow the use of recombinant or mixed DNA to be used more and more and in increasingly safer conditions. However there are still many problems and restrictions with using recombinant DNA such as side-effects or long term changes and the effect a new characteristic will have on its surrounding environment, be it the human body or a whole environmental ecosystem. Whilst genetic engineering has been beneficial in many ways increasing plant yields or improving human health, the statement, The use of recombinant DNA can only benefit humans, can be discussed and in almost all situations it is found not to be true as discussed below. Genetic engineering is used frequently in the agricultural industry for many purposes :- For ...

b) Government scientists have stated that the artificial insertion of DNA into plants, a technique unique to genetic engineering, can cause a variety of significant problems with plant foods. Such genetic engineering can increase the levels of known toxicants in foods and introduce new toxicants and health concerns.. (c) Mandatory identification of foods produced through genetic engineering can provide a critical method for tracking the potential health effects of eating genetically engineered foods.. (d) No federal or California law requires that food producers identify whether foods were produced using genetic engineering. At the same time, the U.S. Food and Drug Administration does not require safety studies of such foods. Unless these foods contain a known allergen, the FDA does not even require developers of genetically engineered crops to consult with the agency.. (e) Polls consistently show that more than 90 percent of the public want to know if their food was produced using genetic ...
The process of genetic engineering allows for the structure of genes to be altered. It is a deliberate modification which occurs through the direct manipulation of the genetic material of an organism. DNA is either added or subtracted to produce one or more new traits that were not found in that organism before.. With genetic engineering, it becomes possible to create plants that can resist herbicides while they grow. It also becomes possible to create new threats to our food supply or personal health because viruses and bacteria continue to adapt to the changes that are produced through this process.. Here are the advantages and disadvantages of genetic engineering to consider. ...

The human race had acquired the ability to wreak change on the interior as well as the exterior of earths ecosystems. Doors began to open to designer bugs able to make a huge range of proteins for the pharmaceutical and chemical industries, and, further down the road, to genetic techniques capable of revolutionizing the slow-paced plant and animal breeding industries and the treatment of genetic diseases. Government, agribusiness, pharmaceutical and chemical capital has been moving through those doors ever since. A quarter-century on, the brave new world of genetic engineering is ...
Genetic engineering involves the isolation, manipulation, transfer, and reintroduction of DNA into cells or model organisms usually to express a protein. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, or producing a new protein or enzyme, along with altering the organism to produce more of certain traits. Genetic engineering can be used to alter a life form for adaptability to other worlds by introducing traits that will aid in survival. ...

This project applies biotechnology to effectively mitigate the impact of pests and pathogens on priority floral crops and develops systems that can be manipulated to preserve select hardwood tree taxa for future genetic engineering applications. Genetic engineering of floral crops for pest and pathogen resistance contributes to sustainable production. There has been little research done on migratory nematodes such as Pratylenchus, and this project addresses the use of transgenes that may be effective in controlling Pratylenchus. Viruses are always a problem for propagated plants, particularly flower bulb crops that are propagated from the same bulb for many years. This project determines if an RNAi approach is effective for control of Cucumber mosaic virus (CMV), an economically important virus that affects numerous crops. In vitro manipulation of plants through genetic engineering allows for rapid clonal propagation, ploidy level manipulation, and preservation of germplasm and cryopreservation. ...

As my son watched the Teenage Mutant Ninja Turtles series, he suddenly remembered that Dad also works with mutations. He began to ask questions about how the mutagen (the cause of the mutation) works. I decided to show him one of the most important mutagens affecting our planet Earth: the sun.. Suffice it to say my boy was disappointed, isnt there anything else? More exciting? Some greenish oozing chemical that will turn a turtle into a ninja turtle?. As I considered it, I realized that there is … well sort of… but like anything in life it is complicated and requires a complex explanation. Heres my attempt to simplify things:. The sun distributes a host of rays that reach Earth, including light and UV radiation. This is the same radiation that tans us on the beach for which we apply sun screen and other protective measures. We know that we need to protect ourselves from UV radiation because it has the potential to cause cancer, more precisely - melanoma (skin cancer).. Both UV radiation ...

So, the title genetic engineering and biotechnology should imply the use of recombinant DNA technology in large scale production of foods, industrials products, or treatment options. This is cool! But is this realistic? Is it possible for a person to have a sensible career by only having the knowledge of engineering various organisms? May be it is possible but only if you are in a research career. It requires for a team of researchers ten to twenty years developing a single marketable transgenic animal or plant. Because the job can be done by any molecular biologists there is little reason to have a separate discipline for genetic engineers who only know the techniques of recombinant DNA ...

An ecological cascade effect is a series of secondary extinctions that is triggered by the primary extinction of a key species in an ecosystem. Secondary extinctions are likely to occur when the threatened species are: dependent on a few specific food sources, mutualistic (dependent on the key species in some way), or forced to coexist with an invasive species that is introduced to the ecosystem. Species introductions to a foreign ecosystem can often devastate entire communities, and even entire ecosystems. These exotic species monopolize the ecosystem's resources, and since they have no natural predators to decrease their growth, they are able to increase indefinitely. Olsen et al.[1] showed that exotic species have caused lake and estuary ecosystems to go through cascade effects due to loss of algae, crayfish, mollusks, fish, amphibians, and birds. However, the principal cause of cascade effects is the loss of top predators as the key species. As a result of this loss, a dramatic increase ...
