    Description: Escherichia coli strain MRE600 was originally identified for its low RNase I activity and has therefore been widely adopted by the biomedical research community as a preferred source for the expression and purification of transfer RNAs and ribosomes. Despite its widespread use, surprisingly little information about its genome or genetic content exists. Here, we present the first de novo assembly and description of the MRE600 genome and epigenome. To provide context to these studies of MRE600, we include comparative analyses with E. coli K-12 MG1655 (K12). Pacific Biosciences Single Molecule, Real-Time sequencing reads were assembled into one large chromosome (4.83 Mb) and three smaller plasmids (89.1, 56.9, and 7.1 kb). Interestingly, the 7.1-kb plasmid possesses genes encoding a colicin E1 protein and its associated immunity protein. The MRE600 genome has a G + C content of 50.8% and contains a total of 5,181 genes, including 4,913 protein-encoding genes and 268 RNA genes. We identified 41,469 modified DNA bases (0.83% of total) and found that MRE600 lacks the gene for type I methyltransferase, EcoKI. Phylogenetic, taxonomic, and genetic analyses demonstrate that MRE600 is a divergent E. coli strain that displays features of the closely related genus, Shigella . Nevertheless, comparative analyses between MRE600 and E. coli K12 show that these two strains exhibit nearly identical ribosomal proteins, ribosomal RNAs, and highly homologous tRNA species. Substantiating prior suggestions that MRE600 lacks RNase I activity, the RNase I-encoding gene, rna , contains a single premature stop codon early in its open-reading frame.

    Description: It is estimated that approximately 1.1 billion people globally drink unsafe water. We previously reported both a novel copper-alginate bead, which quickly reduces pathogen loading in waste streams and the incorporation of these beads into a novel swirl flow bioreactor (SFB), of low capital and running costs and of simple construction from commercially available plumbing pipes and fittings. The purpose of the present study was to trial this system for pathogen reduction in waste streams from an operating Dewats system in Hinjewadi, Pune, India and in both simulated and real waste streams in Seattle, Washington, USA. The trials in India, showed a complete inactivation of coliforms in the discharged effluent (Mean Log removal Value (MLRV) = 3.51), accompanied by a total inactivation of E. coli with a MLRV of 1.95. The secondary clarifier effluent also showed a 4.38 MLRV in viable coliforms during treatment. However, the system was slightly less effective in reducing E. coli viability, with a MLRV of 1.80. The trials in Seattle also demonstrated the efficacy of the system in the reduction of viable bacteria, with a LRV of 5.67 observed of viable Raoultella terrigena cells (100%).

    Description: The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains coding sequences only for hypothetical proteins. Insights into the commensal and virulence behavior of N. meningitidis can be gleaned from the genome, in which sequences for structural proteins of the pilus are clustered and several coding regions unique to serogroup B capsular polysaccharide synthesis can be identified. Finally, N. meningitidis contains more genes that undergo phase variation than any pathogen studied to date, a mechanism that controls their expression and contributes to the evasion of the host immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tettelin, H -- Saunders, N J -- Heidelberg, J -- Jeffries, A C -- Nelson, K E -- Eisen, J A -- Ketchum, K A -- Hood, D W -- Peden, J F -- Dodson, R J -- Nelson, W C -- Gwinn, M L -- DeBoy, R -- Peterson, J D -- Hickey, E K -- Haft, D H -- Salzberg, S L -- White, O -- Fleischmann, R D -- Dougherty, B A -- Mason, T -- Ciecko, A -- Parksey, D S -- Blair, E -- Cittone, H -- Clark, E B -- Cotton, M D -- Utterback, T R -- Khouri, H -- Qin, H -- Vamathevan, J -- Gill, J -- Scarlato, V -- Masignani, V -- Pizza, M -- Grandi, G -- Sun, L -- Smith, H O -- Fraser, C M -- Moxon, E R -- Rappuoli, R -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1809-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710307" target="_blank"〉PubMed〈/a〉

    Description: Chromosome 2 of Plasmodium falciparum was sequenced; this sequence contains 947,103 base pairs and encodes 210 predicted genes. In comparison with the Saccharomyces cerevisiae genome, chromosome 2 has a lower gene density, introns are more frequent, and proteins are markedly enriched in nonglobular domains. A family of surface proteins, rifins, that may play a role in antigenic variation was identified. The complete sequencing of chromosome 2 has shown that sequencing of the A+T-rich P. falciparum genome is technically feasible.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gardner, M J -- Tettelin, H -- Carucci, D J -- Cummings, L M -- Aravind, L -- Koonin, E V -- Shallom, S -- Mason, T -- Yu, K -- Fujii, C -- Pederson, J -- Shen, K -- Jing, J -- Aston, C -- Lai, Z -- Schwartz, D C -- Pertea, M -- Salzberg, S -- Zhou, L -- Sutton, G G -- Clayton, R -- White, O -- Smith, H O -- Fraser, C M -- Adams, M D -- Venter, J C -- Hoffman, S L -- R01 AI40125-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1998 Nov 6;282(5391):1126-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9804551" target="_blank"〉PubMed〈/a〉

    Description: Neisseria meningitidis is a major cause of bacterial septicemia and meningitis. Sequence variation of surface-exposed proteins and cross-reactivity of the serogroup B capsular polysaccharide with human tissues have hampered efforts to develop a successful vaccine. To overcome these obstacles, the entire genome sequence of a virulent serogroup B strain (MC58) was used to identify vaccine candidates. A total of 350 candidate antigens were expressed in Escherichia coli, purified, and used to immunize mice. The sera allowed the identification of proteins that are surface exposed, that are conserved in sequence across a range of strains, and that induce a bactericidal antibody response, a property known to correlate with vaccine efficacy in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pizza, M -- Scarlato, V -- Masignani, V -- Giuliani, M M -- Arico, B -- Comanducci, M -- Jennings, G T -- Baldi, L -- Bartolini, E -- Capecchi, B -- Galeotti, C L -- Luzzi, E -- Manetti, R -- Marchetti, E -- Mora, M -- Nuti, S -- Ratti, G -- Santini, L -- Savino, S -- Scarselli, M -- Storni, E -- Zuo, P -- Broeker, M -- Hundt, E -- Knapp, B -- Blair, E -- Mason, T -- Tettelin, H -- Hood, D W -- Jeffries, A C -- Saunders, N J -- Granoff, D M -- Venter, J C -- Moxon, E R -- Grandi, G -- Rappuoli, R -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1816-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉IRIS, Chiron S.p.A., Via Fiorentina 1, 53100 Siena, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710308" target="_blank"〉PubMed〈/a〉

    Description: The majority of pheromones identified to date are insect pheromones, which are volatile in nature. Identification of nonvolatile pheromones have been relatively rare, especially in vertebrates. Male and female garter snakes use pheromones to mediate sexual behavior. The female sex attractiveness pheromone of the Canadian red-sided garter snake, Thamnophis sirtalis parietalis, consists of a novel series of nonvolatile saturated and monounsaturated long-chain methyl ketones, whereas the male sex recognition pheromone contains squalene. These compounds were isolated, identified, and partially synthesized, and field tests show them to be biologically active.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mason, R T -- Fales, H M -- Jones, T H -- Pannell, L K -- Chinn, J W -- Crews, D -- NICHHD 16687/HD/NICHD NIH HHS/ -- NIMH 00135/MH/NIMH NIH HHS/ -- NIMH 09310/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 21;245(4915):290-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Chemistry, National Heart, Lung, and Blood Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2749261" target="_blank"〉PubMed〈/a〉

    Description: This paper is a study of 2D manipulation without sensing and planning, by exploring the effects of unplanned randomized action sequences on 2D object pose uncertainty. Our approach follows the work of Erdmann and Mason’s sensorless reorienting of an object into a completely determined pose, regardless of its initial pose. While Erdmann and Mason proposed a method using Newtonian mechanics, this paper shows that under some circumstances, a long enough sequence of random actions will also converge toward a determined final pose of the object. This is verified through several simulation and real robot experiments where randomized action sequences are shown to reduce entropy of the object pose distribution. The effects of varying object shapes, action sequences, and surface friction are also explored.
