Abstract
Our method performs as well as GRIMM-Synteny on mammalian genomes, and outperforms it for clades with much greater evolutionary distances such as the Hemiascomycetous yeasts....

Radiation Research (172)1 2009
Abstract
We found that the binding of only one gold nanoparticle to a plasmid-cisplatin complex containing 3197 base pairs increases by a factor of 3 the efficiency of the chemotherapeutic agent cisplatin to produce double-strand breaks in irradiated DNA. Furthermore, adding two cisplatin molecules and one g...

Abstract
We designed. The entire mtDNA sequence was 16 773 base pairs (bp) in length, and the base composition was: A-5,357 bp (31.9%); C-4,444 bp (26.5%); G-2,428 bp (14.5%); T-4,544 bp (27.1%). The structural characteristics [0] of the P. uncia mitochondrial genome were highly similar to these of Felis cat...

DNA organization by the apicoplast-targeted bacterial histone-like protein of Plasmodium falciparum.
Abstract
We report identification of a nuclear-encoded bacterial histone-like protein (PfHU) involved in DNA compaction in the apicoplast. PfHU is associated with apicoplast DNA and is expressed throughout the parasite's intra-erythocytic cycle. The protein binds DNA in a sequence nonspecific manner with a m...

Abstract
We used site-specific crosslinking to create chemical connections at the three interfaces between the three constituent polypeptides of the ring, thereby creating covalently closed cohesin rings. As predicted by the ring entrapment model, this procedure produced dimeric DNA-cohesin structures that a...

Abstract
The 46-kb plasmid pSK41 is the prototype of a family of staphylococcal conjugative multiresistance plasmids. Sequence analyses have revealed the presence of a putative resolvase gene, res, on pSK41, and identical or related genes carried by other staphylococcal multiresistance plasmids. Carriage of...

Abstract
We surveyed influenza sequences from a broad taxonomic distribution and collected 65 full-length genomes representing avian, human and "classic" swine H1N1 lineages in addition to numerous other swine (H1N2, H3N1, and H3N2), human (H2N2, H3N2, and H5N1), and avian (H1N1, H4N6, H5N1, H6N1, H6N6, H6N8...

Abstract
We provide the first phylogenetic analysis of notothenioids using both mtDNA and nuclear gene sequences for a comprehensive sampling of all major lineages in the clade. Maximum parsimony and Bayesian analyses of aligned mtDNA genes, an aligned nuclear gene (S7 ribosomal protein intron 1), and combin...

Abstract
Most of the recognized species of the genus Dionda inhabit drainages of the Gulf of Mexico from central Mexico to central Texas, USA, and have been considered a monophyletic group based on morphological, osteological, and allozyme investigations. Phylogenetic relationships of 15 species of Dionda an...

Abstract
We compared eight plasmids from five Arthrobacter strains in order to identify putative core maintenance genes for replication, segregation, and conjugation. Iteron like sequences were identified on some of the plasmids; however, no genes with obvious similarity to known replication sequences such a...

Abstract
We program diverse molecular self-assembly and disassembly pathways using a 'reaction graph' abstraction to specify complementarity relationships between modular domains in a versatile DNA hairpin motif. Molecular programs are executed for a variety of dynamic functions: catalytic formation of branc...

We tackled some of them using a new combination of maximum likelihood-based methods, developed in order to practice as safe and careful concatenations as possible. First, we used the application concaterpillar on carefully aligned core genes. This application uses a hierarchical likelihood-ratio tes...

Journal of Virology (81)13 2007
Abstract
We show here that DNA ligase IV, which performs the joining step of NHEJ, is degraded as a consequence of adenovirus infection. Degradation is dependent upon E4 34k and E1b 55k, functional proteasomes, and the activity of cellular cullin 5, a component of the adenoviral ubiquitin ligase. DNA ligase...

Abstract
The soluble factors produced either by Ehrlich's ascites carcinoma (EAC) or thymic adherent cells (TAC) of tumor-bearing mice comprising of CD11b(+) and CD11c(+) antigen-presenting cells caused a sharp decrease in prolactin (PRL)-induced ConA-mediated effect on survival of PNA(+) thymocytes. Similar...

Abstract
We analyze a Bayesian model for estimating species trees that accounts for the stochastic variation expected for gene trees from multiple unlinked loci sampled from a single species history after a coalescent process. Application of the model to a 106-gene data set from yeast shows that the set of g...

Abstract
We found that Mhr1 is required for the hypersuppressiveness of HS [ori5] [rho(-)] mtDNA harboring ori5, one of the replication origins of normal ([rho(+)]) mtDNA. In addition, we detected an Ntg1-stimulated double-strand break at the ori5 locus. Purified Ntg1, a base excision repair enzyme, introduc...

We have established that supermatrices derived from data sets composed mainly by genes suspected to be essential for bacterial cellular life perform better on the recovery of vertical signal than those composed by widely distributed genes. In addition, we show that the "Transcription" category of ge...

For the number of replicates needed for accurate estimates of support in resampling plans, a diagram is provided that helps to address the question whether apparently different support values really differ significantly.

Abstract
We tested the negative model by using a deletion mutant devoid of all prohead genes and FI in an in vivo cos cleavage assay; in this deleted phage, the cohesive ends were not cut. When lambda proheads and gpFI were provided in vivo via a second prophage, cutting was restored, and gpFI was required,...

Abstract
I without accessory sites, were selected in E. coli. Some single mutants can resolve a res x site I plasmid (that is, with one res and one site I), but two or more activating mutations are necessary for efficient resolution of a site I x site I plasmid. Site I x site I resolution by hyperactive muta...

Stretching of DNA molecules helps to resolve detail during the fluorescence microscopy of both single DNA molecules and single DNA-protein complexes. To make stretching occur, intricate procedures of specimen preparation and manipulation have been developed in previous studies. By contrast, the pres...

Our previous study suggested that tandem multimers ("concatemers") formed mainly by the Mhr1p (a yeast nuclear gene-encoded mtDNA-recombination protein)-dependent pathway are required for mtDNA partitioning into buds with concomitant monomerization. The transmission of a few randomly selected clones...

Genomic representations using concatenates of Type IIB restriction endonuclease digestion fragments.
Abstract
We have developed a method for genomic representation using Type IIB restriction endonucleases. Representation by concatenation of restriction digests, or RECORD, is an approach to sample the fragments generated by cleavage with these enzymes. Here, we show that the RECORD libraries may be used for...

Abstract
We describe here that DEK has a clear preference for supercoiled and four-way junction DNA. In the presence of topoisomerase II, DEK stimulates intermolecular catenation of circular DNA molecules. DEK also increases the probability of intermolecular ligation of linear DNA molecules by DNA ligase. Th...

Abstract
Successive viral passage of Spodoptera exigua multicapsid nucleopolyhedrovirus (SeMNPV) in the S. exigua cell line Se301 leads to the rapid accumulation of the non-hr origin of DNA replication (ori) as large concatemers. Passage of SeMNPV in two other S. exigua cell lines, SeUCR1 and SeIZD2109, did...
