Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Databases containing information about PROTEINS such as AMINO ACID SEQUENCE; PROTEIN CONFORMATION; and other properties.
Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
Sequence Analysis, Protein
Hydrogen-donating proteins that participates in a variety of biochemical reactions including ribonucleotide reduction and reduction of PEROXIREDOXINS. Thioredoxin is oxidized from a dithiol to a disulfide when acting as a reducing cofactor. The disulfide form is then reduced by NADPH in a reaction catalyzed by THIOREDOXIN REDUCTASE.
Site-Specific DNA-Methyltransferase (Adenine-Specific)
An enzyme responsible for producing a species-characteristic methylation pattern on adenine residues in a specific short base sequence in the host cell DNA. The enzyme catalyzes the methylation of DNA adenine in the presence of S-adenosyl-L-methionine to form DNA containing 6-methylaminopurine and S-adenosyl-L-homocysteine. EC 126.96.36.199.
Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases.
RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms.
Nucleic Acid Conformation
A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
RNA, Small Interfering
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
DNA Restriction Enzymes
Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another. EC 3.21.1.
Deoxyribonucleases, Type II Site-Specific
Enzyme systems containing a single subunit and requiring only magnesium for endonucleolytic activity. The corresponding modification methylases are separate enzymes. The systems recognize specific short DNA sequences and cleave either within, or at a short specific distance from, the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 188.8.131.52.
The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.
DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

Bacteriophage phiYeO3-12, specific for Yersinia enterocolitica serotype O:3, is related to coliphages T3 and T7. (1/25)Bacteriophage phiYeO3-12 is a lytic phage of Yersinia enterocolitica serotype O:3. The phage receptor is the lipopolysaccharide O chain of this serotype that consists of the rare sugar 6-deoxy-L-altropyranose. A one-step growth curve of phiYeO3-12 revealed eclipse and latent periods of 15 and 25 min, respectively, with a burst size of about 120 PFU per infected cell. In electron microscopy phiYeO3-12 virions showed pentagonal outlines, indicating their icosahedral nature. The phage capsid was shown to be composed of at least 10 structural proteins, of which a protein of 43 kDa was predominant. N-terminal sequences of three structural proteins were determined, two of them showing strong homology to structural proteins of coliphages T3 and T7. The phage genome was found to consist of a double-stranded DNA molecule of 40 kb without cohesive ends. A physical map of the phage DNA was constructed using five restriction enzymes. The phage infection could be effectively neutralized using serum from a rabbit immunized with whole phiYeO3-12 particles. The antiserum also neutralized T3 infection, although not as efficiently as that of phiYeO3-12. phiYeO3-12 was found to share, in addition to the N-terminal sequence homology, several common features with T3, including morphology and nonsubjectibility to F exclusion. The evidence conclusively indicated that phiYeO3-12 is the first close relative of phage T3 to be described. (+info)
Insertion of the T3 DNA polymerase thioredoxin binding domain enhances the processivity and fidelity of Taq DNA polymerase. (2/25)Insertion of the T3 DNA polymerase thioredoxin binding domain (TBD) into the distantly related thermostable Taq DNA polymerase at an analogous position in the thumb domain, converts the Taq DNA polymerase from a low processive to a highly processive enzyme. Processivity is dependent on the presence of thioredoxin. The enhancement in processivity is 20-50-fold when compared with the wild-type Taq DNA polymerase or to the recombinant polymerase in the absence of thioredoxin. The recombinant Taq DNA pol/TBD is thermostable, PCR competent and able to copy repetitive deoxynucleotide sequences six to seven times more faithfully than Taq DNA polymerase and makes 2-3-fold fewer AT-->GC transition mutations.

The genome sequence of Yersinia pestis bacteriophage phiA1122 reveals an intimate history with the coliphage T3 and T7 genomes. (3/25)The genome sequence of bacteriophage phiA1122 has been determined. phiA1122 grows on almost all isolates of Yersinia pestis and is used by the Centers for Disease Control and Prevention as a diagnostic agent for the causative agent of plague. phiA1122 is very closely related to coliphage T7; the two genomes are colinear, and the genome-wide level of nucleotide identity is about 89%. However, a quarter of the phiA1122 genome, one that includes about half of the morphogenetic and maturation functions, is significantly more closely related to coliphage T3 than to T7. It is proposed that the yersiniophage phiA1122 recombined with a close relative of the Y. enterocolitica phage phiYeO3-12 to yield progeny phages, one of which became the classic T3 coliphage of Demerec and Fano (M. Demerec and U. Fano, Genetics 30:119-136, 1945). (+info)
Characterization of bacteriophage T3 DNA ligase. (4/25)DNA ligases of bacteriophage T4 and T7 have been widely used in molecular biology for decades, but little is known about bacteriophage T3 DNA ligase. Here is the first report on the cloning, expression and biochemical characterization of bacteriophage T3 DNA ligase. The polyhistidine-tagged recombinant T3 DNA ligase was shown to be an ATP-dependent enzyme. The enzymatic activity was not affected by high concentration of monovalent cations up to 1 M, whereas 2 mM ATP could inhibit its activity by 50%. Under optimal conditions (pH 8.0, 0.5 mM ATP, 5 mM DTT, 1 mM Mg(2+) and 300 mM Na(+)), 1 fmol of T3 DNA ligase could achieve 90% ligation of 450 fmol of cohesive dsDNA fragments in 30 min. T3 DNA ligase was shown to be over 5-fold more efficient than T4 DNA ligase for ligation of cohesive DNA fragments, but less active for blunt-ended DNA fragments. Phylogenetic analysis showed that T3 DNA ligase is more closely related to T7 DNA ligase than to T4 DNA ligase. (+info)
In vivo hydrolysis of S-adenosylmethionine induces the met regulon of Escherichia coli. (5/25)Regulation of methionine biosynthesis in Escherichia coli involves a complex of the MetJ aporepressor protein and S-adenosylmethionine (SAM) repressing expression of most genes in the met regulon. To test the role of SAM in the regulation of met genes directly, SAM pools were depleted by the in vivo expression of the cloned plasmid vector-based coliphage T3 SAM hydrolase (SAMase) gene. Cultures with in vivo SAMase activity were assayed for expression of the metA, B, C, E, F, H, J, K and R genes in cells grown in methionine-rich complete media as well as in defined media with and without l-methionine. In vivo SAMase activity dramatically induced expression between 11- and nearly 1000-fold depending on the gene assayed for all but metJ and metH, and these genes were induced over twofold. metJ : : Tn5 (aporepressor defective) and metK : : Tn5 (SAM synthetase impaired; produces <5 % of wild-type SAM) strains containing in vivo SAMase activity produced even higher met gene activity than that seen in comparably prepared cells with wild-type genes for all but metJ in a MetJ-deficient background. The SAMase-mediated hyperinduction of metH in wild-type cells and of the met genes assayed in metJ : : Tn5 and metK : : Tn5 cells provokes questions about how other elements such as the MetR activator protein or factors beyond the met regulon itself might be involved in the regulation of genes responsible for methionine biosynthesis.

Compensatory evolution in response to a novel RNA polymerase: orthologous replacement of a central network gene. (6/25)A bacteriophage genome was forced to evolve a new system of regulation by replacing its RNA polymerase (RNAP) gene, a central component of the phage developmental pathway, with that of a relative. The experiment used the obligate lytic phage T7 and the RNAP gene of phage T3. T7 RNAP uses 17 phage promoters, which are responsible for all middle and late gene expression, DNA replication, and progeny maturation, but the enzyme has known physical contacts with only 2 other phage proteins. T3 RNAP was supplied in trans by the bacterial host to a T7 genome lacking its own RNAP gene and the phage population was continually propagated on naive bacteria throughout the adaptation. Evolution of the T3 RNAP gene was thereby prevented, and selection was for the evolution of regulatory signals throughout the phage genome. T3 RNAP transcribes from T7 promoters only at low levels, but a single mutation in the promoter confers high expression, providing a ready mechanism for reevolution of gene expression in this system. When selected for rapid growth, fitness of the engineered phage evolved from a low of 5 doublings/h to 33 doublings/h, close to the expected maximum of 37 doublings/h. However, the experiment was terminated before it could be determined accurately that fitness had reached an obvious plateau, and it is not known whether further adaptation could have resulted in complete recovery of fitness. More than 30 mutations were observed in the evolved genome, but changes were found in only 9 of the 16 promoters, and several coding changes occurred in genes with no known contacts with the RNAP. Surprisingly, the T7 genome adapted to T3 RNAP also maintained high fitness when using T7 RNAP, suggesting that the extreme incompatibility of T7 elements with T3 RNAP is not an invariant property of divergence in these expression systems.

Evolution and the complexity of bacteriophages. (7/25)BACKGROUND: The genomes of both long-genome (> 200 Kb) bacteriophages and long-genome eukaryotic viruses have cellular gene homologs whose selective advantage is not explained. These homologs add genomic and possibly biochemical complexity. Understanding their significance requires a definition of complexity that is more biochemically oriented than past empirically based definitions. HYPOTHESIS: Initially, I propose two biochemistry-oriented definitions of complexity: either decreased randomness or increased encoded information that does not serve immediate needs. Then, I make the assumption that these two definitions are equivalent. This assumption and recent data lead to the following four-part hypothesis that explains the presence of cellular gene homologs in long bacteriophage genomes and also provides a pathway for complexity increases in prokaryotic cells: (1) Prokaryotes underwent evolutionary increases in biochemical complexity after the eukaryote/prokaryote splits. (2) Some of the complexity increases occurred via multi-step, weak selection that was both protected from strong selection and accelerated by embedding evolving cellular genes in the genomes of bacteriophages and, presumably, also archaeal viruses (first tier selection). (3) The mechanisms for retaining cellular genes in viral genomes evolved under additional, longer-term selection that was stronger (second tier selection). (4) The second tier selection was based on increased access by prokaryotic cells to improved biochemical systems. This access was achieved when DNA transfer moved to prokaryotic cells both the more evolved genes and their more competitive and complex biochemical systems. TESTING THE HYPOTHESIS: I propose testing this hypothesis by controlled evolution in microbial communities to (1) determine the effects of deleting individual cellular gene homologs on the growth and evolution of long genome bacteriophages and hosts, (2) find the environmental conditions that select for the presence of cellular gene homologs, (3) determine which, if any, bacteriophage genes were selected for maintaining the homologs and (4) determine the dynamics of homolog evolution. IMPLICATIONS OF THE HYPOTHESIS: This hypothesis is an explanation of evolutionary leaps in general. If accurate, it will assist both understanding and influencing the evolution of microbes and their communities. Analysis of evolutionary complexity increase for at least prokaryotes should include analysis of genomes of long-genome bacteriophages. (+info)
Dispersing biofilms with engineered enzymatic bacteriophage. (8/25)Synthetic biology involves the engineering of biological organisms by using modular and generalizable designs with the ultimate goal of developing useful solutions to real-world problems. One such problem involves bacterial biofilms, which are crucial in the pathogenesis of many clinically important infections and are difficult to eradicate because they exhibit resistance to antimicrobial treatments and removal by host immune systems. To address this issue, we engineered bacteriophage to express a biofilm-degrading enzyme during infection to simultaneously attack the bacterial cells in the biofilm and the biofilm matrix, which is composed of extracellular polymeric substances. We show that the efficacy of biofilm removal by this two-pronged enzymatic bacteriophage strategy is significantly greater than that of nonenzymatic bacteriophage treatment. Our engineered enzymatic phage substantially reduced bacterial biofilm cell counts by approximately 4.5 orders of magnitude ( approximately 99.997% removal), which was about two orders of magnitude better than that of nonenzymatic phage. This work demonstrates the feasibility and benefits of using engineered enzymatic bacteriophage to reduce bacterial biofilms and the applicability of synthetic biology to an important medical and industrial problem.

A packaging and delivery system for aerial release of Phytoseiidae for biological control - Semantic Scholar
A new packaging system for the aerial release of phytoseiids was designed and tested in the laboratory and in the field. The observed escapes before and after release, mortality during all stages of release, and fecundity after release indicated that the system was suitable for transporting and distributing phytoseiids. Other evaluated properties of the packaging system included container opening efficiency, container dispersion over the field at several fly-over altitudes, and the probability of containers to be lodged in the cassava canopy. Aerial release trials followed by recoveries of viable adult female phytoseiids from the target fields demonstrated the feasibility of aerial releases as a means for distributing phytoseiid natural enemies.

Evolution of genetic architectures | Proceedings of the Royal Society of London B: Biological Sciences
The predictions of our model-notably, that the number of loci in a genetic architecture and the variance of their allelic contributions are greatest for traits under intermediate selection-are robust to choices of population-genetic parameters. The non-monotonic relation between selection pressure on a trait and the size of its genetic architecture, L, holds regardless of population size, but the location of maximum L is shifted towards weaker selection in larger populations (see electronic supplementary material, figure S5). This result is compatible with our explanation involving compensatory evolution: selection is more efficient in large populations, and so compensatory evolution occurs at smaller selection coefficients. Likewise, when the mutation rate is smaller the resulting equilibrium number of controlling loci is reduced (see electronic supplementary material, figure S6). This result is again compatible with the explanation of compensatory evolution, which requires frequent mutations. ...

Environmental epistasis in catalytic RNA | Proceedings of the Royal Society of London B: Biological Sciences
Two trajectories are possible in converting a GC base pair to an AU base pair. One of them passes through a GU base pair intermediate, the other through an AC mismatch intermediate (see figure 4; electronic supplementary material, figure S3). In our data, a ribozyme with the GU intermediate is always more active than that with the AC intermediate (from +1.4 to +22.7%; average = +10.3%). This confirms predictions of the relative effects of these two intermediates based on the geometry of base pairs , experimental measurements  and bioinformatic analysis of tRNA evolution . Our data support a continuous ridge or neutral network model (see Landscapes caused by a base pair switch in Supporting Information, electronic supplementary material) of compensatory evolution in RNA secondary structure, because in our experiments, the GU intermediate shows a significant decrease in fitness only in a single instance, and in this instance the base pair switch is not compensatory but ...

These are the masters. Other services (such as Web App Proxy Server and MapReduce Job History server) are usually run either on dedicated hardware or on shared infrastructure, depending upon the load.. The rest of the machines in the cluster act as both DataNode and NodeManager. These are the workers. ...

Fruit Quality as influenced by Wax Application
DAnjou pears harvested at commercial maturity from a block of 6 trees were immediately divided into 2 lots. One lot was placed in refrigerated storage (1 °C) for 90 days and then transferred to room temperature 24 hours prior to wax application. The second lot of fruit was waxed 24 hours after harvest, using both hot and cold wax drying techniques. Prior to waxing, the pears were drenched in hot water (40 °C), and passed over rotary dewatering brushes for 30 sec before going into the wax applicator. Using a commercial pear wax formulation (Shieldbrite PR160C, Shield-brite Corp, Kirkland. WA) pears were waxed at the approximate rate of 10 ml/min (6,804 Kg fruit/3.8 liters). Waxed pears were dried in a commercial hot-drying tunnel held at 60 °C (Van Doren Sales, Inc., Wenatchee, WA) or a cold drier operated at 0 °C (Sirron, marketed by MARQ International Packaging Systems, Inc., Yakima, WA) for 2 min. After the fruit surface had dried, 100 pears were packed in pulp fiber trays, enclosed in a ...

As these new techniques continue to improve, we will be able to answer many of the questions we have now, while likely raising many new ones. ...
Dissertation or Thesis | RNA structures and their molecular evolution in HIV: evolution of robustness in RNA structures and...
The known functions of RNA structures have expanded of late, such that RNA is considered a more active player in molecular biology. The presence of RNA secondary structure in a sequence should constrain evolution of its constituent nucleotides because of the requirement to maintain the base-pairing regions in the structure. In a previous work, we found support for this hypothesis in nine molecules from various organisms, the exception being a structure found in a protein-coding region of the HIV-1 genome. In this work, I examine the interaction of constraints imposed by RNA structures and host-induced hypermutation on molecular evolution in HIV-1. I conclude that RNA structures in HIV do evolve via compensatory evolution, but that hypermutation can obscure the expected signal. Since RNAs known roles have increased, so have the methods for identification and prediction of RNA structures in genetic sequence. I use a method adapted for searching in multiple coding regions to identify conserved RNA ...
