Four dimers of lambda repressor bound to two suitably spaced pairs of lambda operators form octamers and DNA loops over large distances. (1/11892)

Transcription factors that are bound specifically to DNA often interact with each other over thousands of base pairs [1] [2]. Large DNA loops resulting from such interactions have been observed in Escherichia coli with the transcription factors deoR [3] and NtrC [4], but such interactions are not, as yet, well understood. We propose that unique protein complexes, that are not present in solution, may form specifically on DNA. Their uniqueness would make it possible for them to interact tightly and specifically with each other. We used the repressor and operators of coliphage lambda to construct a model system in which to test our proposition. lambda repressor is a dimer at physiological concentrations, but forms tetramers and octamers at a hundredfold higher concentration. We predict that two lambda repressor dimers form a tetramer in vitro when bound to two lambda operators spaced 24 bp apart and that two such tetramers interact to form an octamer. We examined, in vitro, relaxed circular plasmid DNA in which such operator pairs were separated by 2,850 bp and 2,470 bp. Of these molecules, 29% formed loops as seen by electron microscopy (EM). The loop increased the tightness of binding of lambda repressor to lambda operator. Consequently, repression of the lambda PR promoter in vivo was increased fourfold by the presence of a second pair of lambda operators, separated by a distance of 3,600 bp.  (+info)

A cytomegalovirus glycoprotein re-routes MHC class I complexes to lysosomes for degradation. (2/11892)

Mouse cytomegalovirus (MCMV) early gene expression interferes with the major histocompatibility complex class I (MHC class I) pathway of antigen presentation. Here we identify a 48 kDa type I transmembrane glycoprotein encoded by the MCMV early gene m06, which tightly binds to properly folded beta2-microglobulin (beta2m)-associated MHC class I molecules in the endoplasmic reticulum (ER). This association is mediated by the lumenal/transmembrane part of the protein. gp48-MHC class I complexes are transported out of the ER, pass the Golgi, but instead of being expressed on the cell surface, they are redirected to the endocytic route and rapidly degraded in a Lamp-1(+) compartment. As a result, m06-expressing cells are impaired in presenting antigenic peptides to CD8(+) T cells. The cytoplasmic tail of gp48 contains two di-leucine motifs. Mutation of the membrane-proximal di-leucine motif of gp48 restored surface expression of MHC class I, while mutation of the distal one had no effect. The results establish a novel viral mechanism for downregulation of MHC class I molecules by directly binding surface-destined MHC complexes and exploiting the cellular di-leucine sorting machinery for lysosomal degradation.  (+info)

Novel endotheliotropic herpesviruses fatal for Asian and African elephants. (3/11892)

A highly fatal hemorrhagic disease has been identified in 10 young Asian and African elephants at North American zoos. In the affected animals there was ultrastructural evidence for herpesvirus-like particles in endothelial cells of the heart, liver, and tongue. Consensus primer polymerase chain reaction combined with sequencing yielded molecular evidence that confirmed the presence of two novel but related herpesviruses associated with the disease, one in Asian elephants and another in African elephants. Otherwise healthy African elephants with external herpetic lesions yielded herpesvirus sequences identical to that found in Asian elephants with endothelial disease. This finding suggests that the Asian elephant deaths were caused by cross-species infection with a herpesvirus that is naturally latent in, but normally not lethal to, African elephants. A reciprocal relationship may exist for the African elephant disease.  (+info)

The haplotype distribution of two genes of citrus tristeza virus is altered after host change or aphid transmission. (4/11892)

Genetic variability of citrus tristeza virus (CTV) was studied using the haplotypes detected by single-strand conformation polymorphism (SSCP) analysis of genes p18 and p20 in six virus populations of two origins. The Spanish group included a CTV isolate and subisolates obtained by graft-transmission to different host species. The other included two subisolates aphid-transmitted from a single Japanese isolate. The homozygosity observed for gene p20 was always significantly higher than that expected under neutral evolution, whereas only three populations showed high homozygosity for p18, suggesting stronger host constraints for p20 than for p18. Sequential transmissions of a Spanish isolate to new host species increased the difference between its population and that of the successive subisolates for gene p18, as estimated by the F statistic. Analysis of molecular variance indicated that variation between both groups of populations was not statistically significant, whereas variations between populations of the same group or within populations were significant for both genes studied. Our data indicate that selection affects the haplotype distribution and that adaptation to a new host can be as important or more as the geographical origin. Variation of the CTV populations after host change or aphid transmission may explain in part the wide biological variability observed among CTV isolates.  (+info)

Bacteriophage SPO1 development: defects in a gene 31 mutant. (5/11892)

SPO1 temperature-sensitive mutant ts14-1, located in cistron 31, has a DD (DNA synthesis-delayed) phenotype at 37 degrees C and produces progeny in a stretched program. At 44 degrees C it behaves as a DO (DNA synthesis-defective) mutant and shuts off the viral RNA synthesis about 10 min after infection. The thermal sensitivity of this mutant is due to the inactivity of gp-31 (the product of gene 31) at 44 degrees C. However, gp-31 is synthesized at that temperature and partly recovers its activity at 37 degrees C. Only 5 min at the permissive temperature is enough to trigger the continuation of the phage program and to produce progeny. The partial defect at 37 degrees C and the expansion of the middle program together with the pleiotropic defects at the nonpermissive temperature could be suitable for the study of the controls involved in bacteriophage development.  (+info)

Evidence that the neck appendages are adsorption organelles in Bacillus subtilis bacteriophage phi29. (6/11892)

A mutant of Bacillus subtilis unable to adsorb phage phi29 efficiently has been isolated. This mutant can be infected by host range mutants of the phage. Since the host range mutations map in cistron 12, which codes for neck appendage protein, this would tend to confirm that these organelles are involved in viral adsorption.  (+info)

Control of corynebacteriophage reproduction by heteroimmune repression. (7/11892)

Corynebacteriophages beta and gamma are closely related but heteroimmune; hence, gamma reproduces in C7(beta). A series of gamma mutants, designated gamma-bin (beta-inhibited), has been isolated. They reproduce in only 2 to 14% of infected C7(beta) cells, and, as a result, plaque with an efficiency of 10(-4) to 10(-5) on this strain. The proportion of C7(beta) cells in which gamma-bin phage can replicate is increased to 30 to 80% when immunity is lifted by UV induction of C7(beta) or by heat induction of C7(beta-tsr3). The gamma-bin mutants carry out a normal vegetative or lysogenic cycle in strain C7 and thus do not appear to be defective in any essential phage function. Infection of C7(beta) by gamma-bin results in cell killing whether the infection is productive or nonproductive. The data support the hypothesis that inhibition of gamma-bin is due to the direct or indirect action of a beta prophage gene. The simplest hypothesis is that gamma-bin phages have sustained mutations in an operator site and that beta repressor now combines with the mutated operator to inhibit normal replication in a significant proportion of infected cells.  (+info)

Correlated genetic and EcoRI cleavage map of Bacillus subtilis bacteriophage phi105 DNA. (8/11892)

The seven previously identified EcoRI cleavage fragments of phi 105 DNA were ordered with respect to their sites of origin on the phage genome by marker rescue. One fragment, H, did not carry any determinants essential for replication. This fragment was totally missing in a deletion mutant which exhibited a lysogenization-defective phenotype. There is a nonessential region on the phi 105 genome which begins in fragment B, spans fragment H, and ends in fragment F. The size of the nonessential region, as estimated by alterations observed in the fragmentation patterns of deletion mutant DNAs, is approximately 2.7 X 10(6) daltons. Two new EcoRI cleavage fragments with molecular weights of approximately 0.2 X 10(6) were detected by autoradiography of 32P-labeled DNA. These small fragments were not located on the cleavage map.  (+info)

To verify the assignment of performance of a distinct viral gene, it is actually probably needed to restore the mutation back to the wild form sequence and deter mine irrespective of whether the phenotype in the rescuant viruses is similar to that of the parental virus. Having said that, the rescue procedures could potentially introduce adventitious muta tions that arise elsewhere in the genome. Meanwhile, it truly is doable the deletion of the target ORF could possibly impact the expression of other viral genes, like individuals in close by regions, since the deleted area may well func tion as a regulatory component vital for that expression of those genes, additionally to encoding the target ORF. Substantial research are necessary to demonstrate that the dele tion does not affect every other gene expression in the viral genome.. Alternatively, a viral mutant that contains a sub tle mutation, such as stage mutations, to inactivate the ORF could be info generated. Examination with the phenotype ...

Efficient, accurate and convenient foreign-gene insertion strategies are crucial for the high-throughput and rapid construction of large DNA viral vectors, but relatively inefficient and labour-intensive methods have limited the application of recombinant viruses. In this study, we applied the nonhomologous insertion (NHI) strategy, which is based on the nonhomologous end joining (NHEJ) repair pathway. Compared to the currently used homologous recombination (HR) strategy, we obtained a higher efficiency of foreign-gene insertion into the herpes simplex virus (HSV) genome that reached 45 % after optimization. By using NHI, we rapidly constructed recombinant reporter viruses using a small amount of clinical viruses, and the recombinant virus was stable for at least ten consecutive passages. The fidelity of NHI ranged from 70-100% and was related to the sequence background of the insertion site according to the sequencing results. Finally, we depict the dynamic process by which the foreign-gene donor

A short homology was found between helper virus and cellular DNA sequences at the junction of v-sis and c-sis, which may have had a role in the original recombination event leading to the generation of simian sarcoma virus. ...
T cells that recognize self antigen are clonally deleted in the thymus--a maturation process that occurs in the context of histocompatibility molecules and the T-cell receptor. The minor lymphocyte stimulation antigens (Mls) effect these deletions through interactions with the V beta portion of the T-cell receptor, thus mimicking bacterial superantigens. Intrigued by the fact that each known Mls gene maps to the same chromosomal region as an endogenous mouse mammary tumour virus (Mtv), we reevaluated the linkage relationships between the two gene families. Here we report perfect concordance in inbred and recombinant inbred mice between the presence of four Mtv proviruses with the expression of Mls gene products. These data suggest a general model in which mammary tumour virus gene products themselves are the ligands that shape a considerable portion of the immunological repertoire of common laboratory mice

Introduction: During productive infection, human cytomegalovirus (HCMV) genes are expressed in a temporal cascade, with temporal phases designated as immediate-early (IE), early, and late. The major IE (MIE) genes, UL123 and UL122 (IE1/IE2), play a critical role in subsequent viral gene expression and the efficiency of viral replication. The early viral genes encode proteins necessary for viral DNA replication. Following viral DNA replication, delayed-early and late viral genes are expressed which encode structural proteins for the virion. The late genes can be divided into two broad classes. At early times the gamma-1 or leaky-late class are expressed at low levels after infection and are dramatically upregulated at late times. In contrast, the gamma-2 or true late genes are expressed exclusively after viral DNA replication. Expression of true late (gamma-2 class) viral genes is completely prevented by inhibition of viral DNA synthesis. Areas covered: This review addresses the viral genes required
The DNA polymerase genes of human cytomegalovirus (HCMV) and varicella-zoster virus (VZV) were inserted separately into the polyhedrin gene of Autographa californica nuclear polyhedrosis virus (AcNPV) by cotransfection of Spodoptera frugiperda (SF9) cells with baculovirus transfer vectors carrying the genes and AcNPV infectious DNA. Infection of SF9 cells with the recombinant viruses resulted in expression from the polyhedrin promoter of proteins of the expected Mrs. These proteins possessed DNA polymerase activities similar to that of the enzymes induced by the respective herpesvirus in infected cells, and were identified as HCMV and VZV DNA polymerase using inhibitors and specific antisera reactive with each enzyme.

Virions of Moloney murine leukemia virus can synthesize two classes of DNA molecules complementary to their 70S RNA. One class consists of molecules about 200 nucleotides long, which are of limited sequence complexity; these molecules are formed preferentially if the dNTP concentration during the reaction is low. The second class consists of very heterogeneous DNA molecules with weight-average size of about 1,000 nucleotides containing at least 70% of the viral RNA sequences in approximately equal concentration. The longest of these molecules can be 5,000 nucleotides long. This second class of DNA is formed in large amounts only in reactions containing dNTP concentrations of 0.2 mM or higher. In such reactions after 24 h of incubation, at least 35% of the input RNA is represented in DNA copies. The ability to make long, representative DNA transcripts of tumor virus RNA provides a source of excellent probes for molecular hybridization. ...
To delineate the function of adenovirus early region 4 (E4) gene products, we constructed a set of mutant viruses which carry defined lesions within this coding region. Deletion and insertion mutations within six of seven known E4 coding regions had no measurable effect on virus growth in cultured cells. A variant carrying a deletion within the last coding region (encoding a 34,000-molecular-weight polypeptide) was modestly defective, and a mutant lacking the majority of the E4 region was severely defective for growth. The phenotypes of the two defective mutants are similar and complex. Both display perturbations in DNA replication, translation of the E2A mRNA, accumulation of late viral mRNAs, and host cell shutoff. ...
Translational energy spectra of H− ions have been measured for capture dissociation of 6 keV H2+ molecular ions in collision with H2 gas. Voltage separation of the ion spectra has been obtained by the application of a biasing potential to the collision gas cell, allowing the sequence of processes taking place in different regions of the spectrometer to be identified. The energy release distribution of the H− spectra and a correlation with the corresponding component of the H+ spectra indicate that the majority of H− are produced from single electron capture-dissociation of H2+ in a double-collision mechanism, H2+ + H2 → H2* + [H2+] and H2* + H2 → H− + H+ + [H2], in which high Rydberg states of the H2* molecule are involved. The H− and corresponding H+ spectral peaks are narrow, with an FWHM of ∼ 0.14 eV in the centre-of-mass system for the H+ and H− ions released from dissociation of H2*, consistent with the suggested mechanism.. ...
