Bacteriophage phi X 174
Bacteriophage phi 6
Bacillus Phages
Lysogeny
The phenomenon by which a temperate phage incorporates itself into the DNA of a bacterial host, establishing a kind of symbiotic relation between PROPHAGE and bacterium which results in the perpetuation of the prophage in all the descendants of the bacterium. Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium.
Escherichia coli
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.

RNA Phages
Bacteriophages whose genetic material is RNA, which is single-stranded in all except the Pseudomonas phage phi 6 (BACTERIOPHAGE PHI 6). All RNA phages infect their host bacteria via the host's surface pili. Some frequently encountered RNA phages are: BF23, F2, R17, fr, PhiCb5, PhiCb12r, PhiCb8r, PhiCb23r, 7s, PP7, Q beta phage, MS2 phage, and BACTERIOPHAGE PHI 6.

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.
DNA, Circular
Any of the covalently closed DNA molecules found in bacteria, many viruses, mitochondria, plastids, and plasmids. Small, polydisperse circular DNA's have also been observed in a number of eukaryotic organisms and are suggested to have homology with chromosomal DNA and the capacity to be inserted into, and excised from, chromosomal DNA. It is a fragment of DNA formed by a process of looping out and deletion, containing a constant region of the mu heavy chain and the 3'-part of the mu switch region. Circular DNA is a normal product of rearrangement among gene segments encoding the variable regions of immunoglobulin light and heavy chains, as well as the T-cell receptor.

Centrifugation, Density Gradient
T-Phages
A series of 7 virulent phages which infect E. coli. The T-even phages T2, T4; (BACTERIOPHAGE T4), and T6, and the phage T5 are called "autonomously virulent" because they cause cessation of all bacterial metabolism on infection. Phages T1, T3; (BACTERIOPHAGE T3), and T7; (BACTERIOPHAGE T7) are called "dependent virulent" because they depend on continued bacterial metabolism during the lytic cycle. The T-even phages contain 5-hydroxymethylcytosine in place of ordinary cytosine in their DNA.
Pseudomonas Phages
Bacteriophage mu
A temperate coliphage, in the genus Mu-like viruses, family MYOVIRIDAE, composed of a linear, double-stranded molecule of DNA, which is able to insert itself randomly at any point on the host chromosome. It frequently causes a mutation by interrupting the continuity of the bacterial OPERON at the site of insertion.
Microscopy, Electron
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
Temperature
RNA, Double-Stranded
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.

DNA-Directed RNA Polymerases
Enzymes that catalyze DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized. (From Enzyme Nomenclature, 1992).

Bacteriophage inactivation at the air-water-solid interface in dynamic batch systems. (1/413)
Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and phiX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were percolated through tubes packed with varying ratios of glass and Teflon beads. MS2 and R17 inactivation was the result of exposure to destructive forces at the dynamic air-water-solid interface. phiX174, however, did not undergo inactivation in similar studies, suggesting that this phage does not accumulate at air-water interfaces or is not affected by interfacial forces in the same manner. Other batch experiments showed that MS2 and R17 were increasingly inactivated during mixing in polypropylene tubes as the ionic strength of the solution was raised (phiX174 was not affected). By the addition of Tween 80 to suspensions of MS2 and R17, phage inactivation was prevented. Our data suggest that viral inactivation in simple dynamic batch experiments is dependent upon (i) the presence of a dynamic air-water-solid interface (where the solid is a hydrophobic surface), (ii) the ionic strength of the solution, (iii) the concentration of surface active compounds in the solution, and (iv) the type of virus used. (+info)Replication fork assembly at recombination intermediates is required for bacterial growth. (2/413)
PriA, a 3' --> 5' DNA helicase, directs assembly of a primosome on some bacteriophage and plasmid DNAs. Primosomes are multienzyme replication machines that contribute both the DNA-unwinding and Okazaki fragment-priming functions at the replication fork. The role of PriA in chromosomal replication is unclear. The phenotypes of priA null mutations suggest that the protein participates in replication restart at recombination intermediates. We show here that PriA promotes replication fork assembly at a D loop, an intermediate formed during initiation of homologous recombination. We also show that DnaC810, encoded by a naturally arising intergenic suppressor allele of the priA2::kan mutation, bypasses the need for PriA during replication fork assembly at D loops in vitro. These findings underscore the essentiality of replication fork restart at recombination intermediates under normal growth conditions in bacteria. (+info)Virus passage through track-etch membranes modified by salinity and a nonionic surfactant. (3/413)
Why do viruses sometimes not pass through larger pores in track-etch filters? Increasing the salinity (0.8 to 160 mM Na+) decreased phiX174 and PRD1 passage through track-etch polycarbonate membranes (sodium dodecyl sulfate coated but not polyvinylpyrrolidone coated) and PRD1 passage through polyester membranes. Undiminished passage when 0.1% Tween 80 was added implied that nonionic virus adsorption occurred and indicated that high levels of salinity decreased virus passage by decreasing electrostatic repulsion that prevented adsorption. (+info)Different trajectories of parallel evolution during viral adaptation. (4/413)
The molecular basis of adaptation is a major focus of evolutionary biology, yet the dynamic process of adaptation has been explored only piecemeal. Experimental evolution of two bacteriophage lines under strong selection led to over a dozen nucleotide changes genomewide in each replicate. At least 96 percent of the amino acid substitutions appeared to be adaptive, and half the changes in one line also occurred in the other. However, the order of these changes differed between replicates, and parallel substitutions did not reflect the changes with the largest beneficial effects or indicate a common trajectory of adaptation. (+info)Evolutionary reversals during viral adaptation to alternating hosts. (5/413)
Experimental adaptation of the bacteriophage phiX174 to a Salmonella host depressed its ability to grow on the traditional Escherichia host, whereas adaptation to Escherichia did not appreciably affect growth on Salmonella. Continued host switching consistently exhibited this pattern. Growth inhibition on Escherichia resulted from two to three substitutions in the major capsid gene. When these phages were forced to grow again on Escherichia, fitness recovery occurred predominantly by reversions at these same sites, rather than by second-site compensatory changes, the more frequently observed mechanism in most microbial systems. The affected residues lie on the virion surface and they alter attachment efficiency, yet they occur in a region distinct from a putative binding region previously identified from X-ray crystallography. These residues not only experienced high rates of evolution in our experiments, but also exhibited high levels of radical amino acid variation among phiX174 and its known relatives, consistent with a history of adaptation involving these sites. (+info)Transfer of immune complexes from erythrocyte CR1 to mouse macrophages. (6/413)
We are developing a potential therapeutic approach for removing pathogens from the circulation of primates in which the pathogen is bound to the complement receptor (CR1) on E using a bispecific mAb complex, a heteropolymer (HP). We have used mAb this approach to demonstrate that cleared prototype pathogens are localized to, phagocytosed in, and destroyed in the liver. Extension of this work to a clinical setting will require a detailed understanding of the mechanism by which the E-bound immune complex substrates are transferred to fixed tissue macrophages in the liver, the transfer reaction. Therefore, we examined an in vitro system to study this process using bacteriophage phiX174 as a model pathogen. E containing phiX174 (bound via an anti-CR1/anti-phiX174 HP) were incubated with P388D1 murine macrophages, and the two cell types were separated by centrifugation through Ficoll. Both E and macrophages were then probed and analyzed by RIA or flow cytometry. The results indicate that all three components of the E-bound IC (phiX174, HP, and CR1) were removed from the E and internalized by the macrophages. We found that transfer requires the Fc portion of IgG, because little transfer of phiX174 occurs when it is bound to E CR1 using a HP containing only Fab fragments. These findings, taken in the context of other studies, suggest a general mechanism for the transfer reaction in which Fc receptors facilitate close juxtaposition of the macrophage to the E-bound IC which then allows a macrophage-associated protease to cleave CR1. The released IC are then internalized and processed by the macrophages. (+info)Purification and characterization of DnaC810, a primosomal protein capable of bypassing PriA function. (7/413)
Escherichia coli strains lacking PriA are severely compromised in their ability to repair UV-damaged DNA and to perform homologous recombination. These phenotypes arise because of a lack of PriA-directed replication fork assembly at recombination intermediates such as D-loops. Naturally arising suppressor mutations in dnaC restore strains carrying the priA2::kan null allele to wild-type function. We have cloned one such gene, dnaC810, and overexpressed, purified, and characterized the DnaC810 protein. DnaC810 can support a PriA-independent synthesis of phiX174 complementary strand DNA. This can be attributed to its ability, unlike wild-type DnaC, to catalyze a SSB-insensitive general priming reaction with DnaB and DnaG on any SSB-coated single-stranded DNA. Gel mobility shift analysis revealed that DnaC810 could load DnaB directly to SSB-coated single-stranded DNA as well as to D loop DNA. This explains the ability of DnaC810 to bypass the requirement for PriA, PriB, PriC, and DnaT during replication fork assembly at recombination intermediates. (+info)Characterization of the binding of spike H protein of bacteriophage phiX174 with receptor lipopolysaccharides. (8/413)
The spike H protein of bacteriophage phiX174 was prepared as a hexa histidine-tagged fusion (HisH). On enzyme-linked plate assaying, HisH was found to bind specifically to the lipopolysaccharides (LPSs) of phiX174-sensitive strains, Escherichia coli C and Salmonella typhimurium Ra chemotype, having the complete oligosaccharide sequence of the R-core on the LPSs. In sharp contrast, HisH bound weakly to the LPSs of phiX174-insensitive strains, i.e. E. coli F583 (Rd(2)) lacking some terminal saccharides and E. coli O111: B4 (smooth strain) having additional O-repeats on the R-core. The fluorescence spectra of HisH changed dose-dependently in the case of the LPS of E. coli C, the intensity increasing and the emission peak shifting to the shorter wavelength side, which was attributable to the hydrophobic interaction of HisH with the LPS. The binding equilibrium was analyzed by fluorometric titration to determine the dissociation constant K(d), 7.02 +/- 0.37 microM, and the Gibbs free energy change DeltaG(0), -29.1 kJ mol(-1) (at 22 degrees C, pH 7.4). Based on the temperature dependence of (K)d in a van't Hoff plot, the standard enthalpy change DeltaH(0) and the entropy change DeltaS(0) were calculated to be +23.7 kJ mol(-1) and 179 J mol(-1) K(-1) at 22 degrees C, respectively, and this binding was thereby concluded to be an entropy-driven reaction.

Single-stranded2
- Mutation in several different cistrons of bacteriophage phi chi 174 blocks net progeny single-stranded DNA synthesis at the late period of infection (15). (caltech.edu)
- Asymmetric synthesis of the viral strand of replicative-form DNA at the late period of phi chi infection is completely inhibited in the presence of a low concentration (35mug/ml) of chloramphenicol (which also blocks net single-stranded viral DNA synthesis). (caltech.edu)
Lambda1
- Given this degree of simplicity, of a bacteriophage like T2 or lambda, it is therefore not at all surprising that these organisms are incapable of a free-living ex- istence, that they are unable to multiply and produce more of their kind except within the confines of a metabolically active host cell.

Virus4
- Transcript from filmed lecture November 15, 1959 Lecture #46 - Virus Genetics: Bacteriophage by J. Lederberg So far our discussion has emphasized behavior of organisms of a considerable degree of complexity. (nih.gov)
- The virus just mentioned, phi X 174, has created some excitement in the world of biochemical genetics since it has recently been found that it ie a unique example of a DNA configuration which is one-~stranded. (nih.gov)
- Bacteriophage XM1 is a dsDNA virus belonging to the Myoviridae family and infecting Vibrio bacteria. (bvsalud.org)
- Bacteriophage T4 is a model virus, well studied genetically and biochemically, but its structure determination has been challenging because of its large size and unusually prolate-shaped, â ¼1,200-Å-long and â ¼860-Å-wide capsid. (bvsalud.org)
Cell3
- In North America, the ability of gloves to protect against micro-organisms is defined by ASTM F 1671, a similar test to ISO 16604, whereby a sample of glove material is placed in a test cell with a bacteriophage under pressure one side. (firemiddleeastmag.com)
- The glove is only confirmed as protective against viruses if there is zero penetration of bacteriophage into the other side of the test cell. (firemiddleeastmag.com)
- Contractile injection systems, including bacteriophage tails, pyocins, and bacterial type VI secretion systems, can efficiently penetrate cell envelopes and become potential antibacterial agents. (bvsalud.org)
