    Description: The metabolic network of a cell represents the catabolic and anabolic reactions that interconvert small molecules (metabolites) through the activity of enzymes, transporters and non-catalyzed chemical reactions. Our understanding of individual metabolic networks is increasing as we learn more about the enzymes that are active in particular cells under particular conditions and as technologies advance to allow detailed measurements of the cellular metabolome. Metabolic network databases are of increasing importance in allowing us to contextualise data sets emerging from transcriptomic, proteomic and metabolomic experiments. Here we present a dynamic database, TrypanoCyc ( http://www.metexplore.fr/trypanocyc/ ), which describes the generic and condition-specific metabolic network of Trypanosoma brucei , a parasitic protozoan responsible for human and animal African trypanosomiasis. In addition to enabling navigation through the BioCyc-based TrypanoCyc interface, we have also implemented a network-based representation of the information through MetExplore, yielding a novel environment in which to visualise the metabolism of this important parasite.

    Description: Plasmodium knowlesi is an intracellular malaria parasite whose natural vertebrate host is Macaca fascicularis (the 'kra' monkey); however, it is now increasingly recognized as a significant cause of human malaria, particularly in southeast Asia. Plasmodium knowlesi was the first malaria parasite species in which antigenic variation was demonstrated, and it has a close phylogenetic relationship to Plasmodium vivax, the second most important species of human malaria parasite (reviewed in ref. 4). Despite their relatedness, there are important phenotypic differences between them, such as host blood cell preference, absence of a dormant liver stage or 'hypnozoite' in P. knowlesi, and length of the asexual cycle (reviewed in ref. 4). Here we present an analysis of the P. knowlesi (H strain, Pk1(A+) clone) nuclear genome sequence. This is the first monkey malaria parasite genome to be described, and it provides an opportunity for comparison with the recently completed P. vivax genome and other sequenced Plasmodium genomes. In contrast to other Plasmodium genomes, putative variant antigen families are dispersed throughout the genome and are associated with intrachromosomal telomere repeats. One of these families, the KIRs, contains sequences that collectively match over one-half of the host CD99 extracellular domain, which may represent an unusual form of molecular mimicry.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2656934/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2656934/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pain, A -- Bohme, U -- Berry, A E -- Mungall, K -- Finn, R D -- Jackson, A P -- Mourier, T -- Mistry, J -- Pasini, E M -- Aslett, M A -- Balasubrammaniam, S -- Borgwardt, K -- Brooks, K -- Carret, C -- Carver, T J -- Cherevach, I -- Chillingworth, T -- Clark, T G -- Galinski, M R -- Hall, N -- Harper, D -- Harris, D -- Hauser, H -- Ivens, A -- Janssen, C S -- Keane, T -- Larke, N -- Lapp, S -- Marti, M -- Moule, S -- Meyer, I M -- Ormond, D -- Peters, N -- Sanders, M -- Sanders, S -- Sargeant, T J -- Simmonds, M -- Smith, F -- Squares, R -- Thurston, S -- Tivey, A R -- Walker, D -- White, B -- Zuiderwijk, E -- Churcher, C -- Quail, M A -- Cowman, A F -- Turner, C M R -- Rajandream, M A -- Kocken, C H M -- Thomas, A W -- Newbold, C I -- Barrell, B G -- Berriman, M -- 085775/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 Oct 9;455(7214):799-803. doi: 10.1038/nature07306.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridgeshire CB10 1SA, UK. ap2@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18843368" target="_blank"〉PubMed〈/a〉

    Description: Candida species are the most common cause of opportunistic fungal infection worldwide. Here we report the genome sequences of six Candida species and compare these and related pathogens and non-pathogens. There are significant expansions of cell wall, secreted and transporter gene families in pathogenic species, suggesting adaptations associated with virulence. Large genomic tracts are homozygous in three diploid species, possibly resulting from recent recombination events. Surprisingly, key components of the mating and meiosis pathways are missing from several species. These include major differences at the mating-type loci (MTL); Lodderomyces elongisporus lacks MTL, and components of the a1/2 cell identity determinant were lost in other species, raising questions about how mating and cell types are controlled. Analysis of the CUG leucine-to-serine genetic-code change reveals that 99% of ancestral CUG codons were erased and new ones arose elsewhere. Lastly, we revise the Candida albicans gene catalogue, identifying many new genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834264/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834264/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Butler, Geraldine -- Rasmussen, Matthew D -- Lin, Michael F -- Santos, Manuel A S -- Sakthikumar, Sharadha -- Munro, Carol A -- Rheinbay, Esther -- Grabherr, Manfred -- Forche, Anja -- Reedy, Jennifer L -- Agrafioti, Ino -- Arnaud, Martha B -- Bates, Steven -- Brown, Alistair J P -- Brunke, Sascha -- Costanzo, Maria C -- Fitzpatrick, David A -- de Groot, Piet W J -- Harris, David -- Hoyer, Lois L -- Hube, Bernhard -- Klis, Frans M -- Kodira, Chinnappa -- Lennard, Nicola -- Logue, Mary E -- Martin, Ronny -- Neiman, Aaron M -- Nikolaou, Elissavet -- Quail, Michael A -- Quinn, Janet -- Santos, Maria C -- Schmitzberger, Florian F -- Sherlock, Gavin -- Shah, Prachi -- Silverstein, Kevin A T -- Skrzypek, Marek S -- Soll, David -- Staggs, Rodney -- Stansfield, Ian -- Stumpf, Michael P H -- Sudbery, Peter E -- Srikantha, Thyagarajan -- Zeng, Qiandong -- Berman, Judith -- Berriman, Matthew -- Heitman, Joseph -- Gow, Neil A R -- Lorenz, Michael C -- Birren, Bruce W -- Kellis, Manolis -- Cuomo, Christina A -- BB/F00513X/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F013566/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0400284/Medical Research Council/United Kingdom -- HHSN266200400001C/AO/NIAID NIH HHS/ -- R01 AI050113/AI/NIAID NIH HHS/ -- R01 AI075096/AI/NIAID NIH HHS/ -- R01 DE015873/DE/NIDCR NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-06/HG/NHGRI NIH HHS/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2009 Jun 4;459(7247):657-62. doi: 10.1038/nature08064.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UCD School of Biomolecular and Biomedical Science, Conway Institute, University College Dublin, Belfield, Dublin 4, Ireland. geraldine.butler@ucd.ie〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19465905" target="_blank"〉PubMed〈/a〉

    Description: Schistosoma mansoni is responsible for the neglected tropical disease schistosomiasis that affects 210 million people in 76 countries. Here we present analysis of the 363 megabase nuclear genome of the blood fluke. It encodes at least 11,809 genes, with an unusual intron size distribution, and new families of micro-exon genes that undergo frequent alternative splicing. As the first sequenced flatworm, and a representative of the Lophotrochozoa, it offers insights into early events in the evolution of the animals, including the development of a body pattern with bilateral symmetry, and the development of tissues into organs. Our analysis has been informed by the need to find new drug targets. The deficits in lipid metabolism that make schistosomes dependent on the host are revealed, and the identification of membrane receptors, ion channels and more than 300 proteases provide new insights into the biology of the life cycle and new targets. Bioinformatics approaches have identified metabolic chokepoints, and a chemogenomic screen has pinpointed schistosome proteins for which existing drugs may be active. The information generated provides an invaluable resource for the research community to develop much needed new control tools for the treatment and eradication of this important and neglected disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756445/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756445/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berriman, Matthew -- Haas, Brian J -- LoVerde, Philip T -- Wilson, R Alan -- Dillon, Gary P -- Cerqueira, Gustavo C -- Mashiyama, Susan T -- Al-Lazikani, Bissan -- Andrade, Luiza F -- Ashton, Peter D -- Aslett, Martin A -- Bartholomeu, Daniella C -- Blandin, Gaelle -- Caffrey, Conor R -- Coghlan, Avril -- Coulson, Richard -- Day, Tim A -- Delcher, Art -- DeMarco, Ricardo -- Djikeng, Appolinaire -- Eyre, Tina -- Gamble, John A -- Ghedin, Elodie -- Gu, Yong -- Hertz-Fowler, Christiane -- Hirai, Hirohisha -- Hirai, Yuriko -- Houston, Robin -- Ivens, Alasdair -- Johnston, David A -- Lacerda, Daniela -- Macedo, Camila D -- McVeigh, Paul -- Ning, Zemin -- Oliveira, Guilherme -- Overington, John P -- Parkhill, Julian -- Pertea, Mihaela -- Pierce, Raymond J -- Protasio, Anna V -- Quail, Michael A -- Rajandream, Marie-Adele -- Rogers, Jane -- Sajid, Mohammed -- Salzberg, Steven L -- Stanke, Mario -- Tivey, Adrian R -- White, Owen -- Williams, David L -- Wortman, Jennifer -- Wu, Wenjie -- Zamanian, Mostafa -- Zerlotini, Adhemar -- Fraser-Liggett, Claire M -- Barrell, Barclay G -- El-Sayed, Najib M -- 086151/Wellcome Trust/United Kingdom -- 5D43TW006580/TW/FIC NIH HHS/ -- 5D43TW007012-03/TW/FIC NIH HHS/ -- AI054711-01A2/AI/NIAID NIH HHS/ -- AI48828/AI/NIAID NIH HHS/ -- R01 GM083873/GM/NIGMS NIH HHS/ -- R01 GM083873-07/GM/NIGMS NIH HHS/ -- R01 GM083873-08/GM/NIGMS NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R01 LM006845-09/LM/NLM NIH HHS/ -- U01 AI048828/AI/NIAID NIH HHS/ -- U01 AI048828-01/AI/NIAID NIH HHS/ -- U01 AI048828-02/AI/NIAID NIH HHS/ -- WT085775/Z/08/Z/Wellcome Trust/United Kingdom -- England -- Nature. 2009 Jul 16;460(7253):352-8. doi: 10.1038/nature08160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Cambridge CB10 1SD, UK. mb4@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19606141" target="_blank"〉PubMed〈/a〉

    Description: Oxamniquine resistance evolved in the human blood fluke (Schistosoma mansoni) in Brazil in the 1970s. We crossed parental parasites differing ~500-fold in drug response, determined drug sensitivity and marker segregation in clonally derived second-generation progeny, and identified a single quantitative trait locus (logarithm of odds = 31) on chromosome 6. A sulfotransferase was identified as the causative gene by using RNA interference knockdown and biochemical complementation assays, and we subsequently demonstrated independent origins of loss-of-function mutations in field-derived and laboratory-selected resistant parasites. These results demonstrate the utility of linkage mapping in a human helminth parasite, while crystallographic analyses of protein-drug interactions illuminate the mode of drug action and provide a framework for rational design of oxamniquine derivatives that kill both S. mansoni and S. haematobium, the two species responsible for 〉99% of schistosomiasis cases worldwide.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136436/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136436/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valentim, Claudia L L -- Cioli, Donato -- Chevalier, Frederic D -- Cao, Xiaohang -- Taylor, Alexander B -- Holloway, Stephen P -- Pica-Mattoccia, Livia -- Guidi, Alessandra -- Basso, Annalisa -- Tsai, Isheng J -- Berriman, Matthew -- Carvalho-Queiroz, Claudia -- Almeida, Marcio -- Aguilar, Hector -- Frantz, Doug E -- Hart, P John -- LoVerde, Philip T -- Anderson, Timothy J C -- 098051/Wellcome Trust/United Kingdom -- 5R21-AI072704/AI/NIAID NIH HHS/ -- 5R21-AI096277/AI/NIAID NIH HHS/ -- C06 RR013556/RR/NCRR NIH HHS/ -- HHSN272201000005I/PHS HHS/ -- R01 AI097576/AI/NIAID NIH HHS/ -- R01-AI097576/AI/NIAID NIH HHS/ -- R21 AI072704/AI/NIAID NIH HHS/ -- R21 AI096277/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1385-9. doi: 10.1126/science.1243106.

    Description: Leishmania species cause a spectrum of human diseases in tropical and subtropical regions of the world. We have sequenced the 36 chromosomes of the 32.8-megabase haploid genome of Leishmania major (Friedlin strain) and predict 911 RNA genes, 39 pseudogenes, and 8272 protein-coding genes, of which 36% can be ascribed a putative function. These include genes involved in host-pathogen interactions, such as proteolytic enzymes, and extensive machinery for synthesis of complex surface glycoconjugates. The organization of protein-coding genes into long, strand-specific, polycistronic clusters and lack of general transcription factors in the L. major, Trypanosoma brucei, and Trypanosoma cruzi (Tritryp) genomes suggest that the mechanisms regulating RNA polymerase II-directed transcription are distinct from those operating in other eukaryotes, although the trypanosomatids appear capable of chromatin remodeling. Abundant RNA-binding proteins are encoded in the Tritryp genomes, consistent with active posttranscriptional regulation of gene expression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1470643/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1470643/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ivens, Alasdair C -- Peacock, Christopher S -- Worthey, Elizabeth A -- Murphy, Lee -- Aggarwal, Gautam -- Berriman, Matthew -- Sisk, Ellen -- Rajandream, Marie-Adele -- Adlem, Ellen -- Aert, Rita -- Anupama, Atashi -- Apostolou, Zina -- Attipoe, Philip -- Bason, Nathalie -- Bauser, Christopher -- Beck, Alfred -- Beverley, Stephen M -- Bianchettin, Gabriella -- Borzym, Katja -- Bothe, Gordana -- Bruschi, Carlo V -- Collins, Matt -- Cadag, Eithon -- Ciarloni, Laura -- Clayton, Christine -- Coulson, Richard M R -- Cronin, Ann -- Cruz, Angela K -- Davies, Robert M -- De Gaudenzi, Javier -- Dobson, Deborah E -- Duesterhoeft, Andreas -- Fazelina, Gholam -- Fosker, Nigel -- Frasch, Alberto Carlos -- Fraser, Audrey -- Fuchs, Monika -- Gabel, Claudia -- Goble, Arlette -- Goffeau, Andre -- Harris, David -- Hertz-Fowler, Christiane -- Hilbert, Helmut -- Horn, David -- Huang, Yiting -- Klages, Sven -- Knights, Andrew -- Kube, Michael -- Larke, Natasha -- Litvin, Lyudmila -- Lord, Angela -- Louie, Tin -- Marra, Marco -- Masuy, David -- Matthews, Keith -- Michaeli, Shulamit -- Mottram, Jeremy C -- Muller-Auer, Silke -- Munden, Heather -- Nelson, Siri -- Norbertczak, Halina -- Oliver, Karen -- O'neil, Susan -- Pentony, Martin -- Pohl, Thomas M -- Price, Claire -- Purnelle, Benedicte -- Quail, Michael A -- Rabbinowitsch, Ester -- Reinhardt, Richard -- Rieger, Michael -- Rinta, Joel -- Robben, Johan -- Robertson, Laura -- Ruiz, Jeronimo C -- Rutter, Simon -- Saunders, David -- Schafer, Melanie -- Schein, Jacquie -- Schwartz, David C -- Seeger, Kathy -- Seyler, Amber -- Sharp, Sarah -- Shin, Heesun -- Sivam, Dhileep -- Squares, Rob -- Squares, Steve -- Tosato, Valentina -- Vogt, Christy -- Volckaert, Guido -- Wambutt, Rolf -- Warren, Tim -- Wedler, Holger -- Woodward, John -- Zhou, Shiguo -- Zimmermann, Wolfgang -- Smith, Deborah F -- Blackwell, Jenefer M -- Stuart, Kenneth D -- Barrell, Bart -- Myler, Peter J -- R01 AI040599/AI/NIAID NIH HHS/ -- R01 AI053667/AI/NIAID NIH HHS/ -- U01 AI040599/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):436-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridgeshire CB10 1SA, UK. alicat@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020728" target="_blank"〉PubMed〈/a〉

    Description: Theileria annulata and T. parva are closely related protozoan parasites that cause lymphoproliferative diseases of cattle. We sequenced the genome of T. annulata and compared it with that of T. parva to understand the mechanisms underlying transformation and tropism. Despite high conservation of gene sequences and synteny, the analysis reveals unequally expanded gene families and species-specific genes. We also identify divergent families of putative secreted polypeptides that may reduce immune recognition, candidate regulators of host-cell transformation, and a Theileria-specific protein domain [frequently associated in Theileria (FAINT)] present in a large number of secreted proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pain, Arnab -- Renauld, Hubert -- Berriman, Matthew -- Murphy, Lee -- Yeats, Corin A -- Weir, William -- Kerhornou, Arnaud -- Aslett, Martin -- Bishop, Richard -- Bouchier, Christiane -- Cochet, Madeleine -- Coulson, Richard M R -- Cronin, Ann -- de Villiers, Etienne P -- Fraser, Audrey -- Fosker, Nigel -- Gardner, Malcolm -- Goble, Arlette -- Griffiths-Jones, Sam -- Harris, David E -- Katzer, Frank -- Larke, Natasha -- Lord, Angela -- Maser, Pascal -- McKellar, Sue -- Mooney, Paul -- Morton, Fraser -- Nene, Vishvanath -- O'Neil, Susan -- Price, Claire -- Quail, Michael A -- Rabbinowitsch, Ester -- Rawlings, Neil D -- Rutter, Simon -- Saunders, David -- Seeger, Kathy -- Shah, Trushar -- Squares, Robert -- Squares, Steven -- Tivey, Adrian -- Walker, Alan R -- Woodward, John -- Dobbelaere, Dirk A E -- Langsley, Gordon -- Rajandream, Marie-Adele -- McKeever, Declan -- Shiels, Brian -- Tait, Andrew -- Barrell, Bart -- Hall, Neil -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 1;309(5731):131-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK. ap2@sanger.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15994557" target="_blank"〉PubMed〈/a〉

    Description: Plasmodium berghei and Plasmodium chabaudi are widely used model malaria species. Comparison of their genomes, integrated with proteomic and microarray data, with the genomes of Plasmodium falciparum and Plasmodium yoelii revealed a conserved core of 4500 Plasmodium genes in the central regions of the 14 chromosomes and highlighted genes evolving rapidly because of stage-specific selective pressures. Four strategies for gene expression are apparent during the parasites' life cycle: (i) housekeeping; (ii) host-related; (iii) strategy-specific related to invasion, asexual replication, and sexual development; and (iv) stage-specific. We observed posttranscriptional gene silencing through translational repression of messenger RNA during sexual development, and a 47-base 3' untranslated region motif is implicated in this process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hall, Neil -- Karras, Marianna -- Raine, J Dale -- Carlton, Jane M -- Kooij, Taco W A -- Berriman, Matthew -- Florens, Laurence -- Janssen, Christoph S -- Pain, Arnab -- Christophides, Georges K -- James, Keith -- Rutherford, Kim -- Harris, Barbara -- Harris, David -- Churcher, Carol -- Quail, Michael A -- Ormond, Doug -- Doggett, Jon -- Trueman, Holly E -- Mendoza, Jacqui -- Bidwell, Shelby L -- Rajandream, Marie-Adele -- Carucci, Daniel J -- Yates, John R 3rd -- Kafatos, Fotis C -- Janse, Chris J -- Barrell, Bart -- Turner, C Michael R -- Waters, Andrew P -- Sinden, Robert E -- New York, N.Y. -- Science. 2005 Jan 7;307(5706):82-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Pathogen Sequencing Unit, Wellcome Trust Sanger Institute, Genome Campus, Hinxton, Cambridge CB10 1SA, UK. nhall@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15637271" target="_blank"〉PubMed〈/a〉

    Description: We report the genome sequence of Theileria parva, an apicomplexan pathogen causing economic losses to smallholder farmers in Africa. The parasite chromosomes exhibit limited conservation of gene synteny with Plasmodium falciparum, and its plastid-like genome represents the first example where all apicoplast genes are encoded on one DNA strand. We tentatively identify proteins that facilitate parasite segregation during host cell cytokinesis and contribute to persistent infection of transformed host cells. Several biosynthetic pathways are incomplete or absent, suggesting substantial metabolic dependence on the host cell. One protein family that may generate parasite antigenic diversity is not telomere-associated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gardner, Malcolm J -- Bishop, Richard -- Shah, Trushar -- de Villiers, Etienne P -- Carlton, Jane M -- Hall, Neil -- Ren, Qinghu -- Paulsen, Ian T -- Pain, Arnab -- Berriman, Matthew -- Wilson, Robert J M -- Sato, Shigeharu -- Ralph, Stuart A -- Mann, David J -- Xiong, Zikai -- Shallom, Shamira J -- Weidman, Janice -- Jiang, Lingxia -- Lynn, Jeffery -- Weaver, Bruce -- Shoaibi, Azadeh -- Domingo, Alexander R -- Wasawo, Delia -- Crabtree, Jonathan -- Wortman, Jennifer R -- Haas, Brian -- Angiuoli, Samuel V -- Creasy, Todd H -- Lu, Charles -- Suh, Bernard -- Silva, Joana C -- Utterback, Teresa R -- Feldblyum, Tamara V -- Pertea, Mihaela -- Allen, Jonathan -- Nierman, William C -- Taracha, Evans L N -- Salzberg, Steven L -- White, Owen R -- Fitzhugh, Henry A -- Morzaria, Subhash -- Venter, J Craig -- Fraser, Claire M -- Nene, Vishvanath -- New York, N.Y. -- Science. 2005 Jul 1;309(5731):134-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA. gardner@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15994558" target="_blank"〉PubMed〈/a〉

    Description: A comparison of gene content and genome architecture of Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, three related pathogens with different life cycles and disease pathology, revealed a conserved core proteome of about 6200 genes in large syntenic polycistronic gene clusters. Many species-specific genes, especially large surface antigen families, occur at nonsyntenic chromosome-internal and subtelomeric regions. Retroelements, structural RNAs, and gene family expansion are often associated with syntenic discontinuities that-along with gene divergence, acquisition and loss, and rearrangement within the syntenic regions-have shaped the genomes of each parasite. Contrary to recent reports, our analyses reveal no evidence that these species are descended from an ancestor that contained a photosynthetic endosymbiont.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉El-Sayed, Najib M -- Myler, Peter J -- Blandin, Gaelle -- Berriman, Matthew -- Crabtree, Jonathan -- Aggarwal, Gautam -- Caler, Elisabet -- Renauld, Hubert -- Worthey, Elizabeth A -- Hertz-Fowler, Christiane -- Ghedin, Elodie -- Peacock, Christopher -- Bartholomeu, Daniella C -- Haas, Brian J -- Tran, Anh-Nhi -- Wortman, Jennifer R -- Alsmark, U Cecilia M -- Angiuoli, Samuel -- Anupama, Atashi -- Badger, Jonathan -- Bringaud, Frederic -- Cadag, Eithon -- Carlton, Jane M -- Cerqueira, Gustavo C -- Creasy, Todd -- Delcher, Arthur L -- Djikeng, Appolinaire -- Embley, T Martin -- Hauser, Christopher -- Ivens, Alasdair C -- Kummerfeld, Sarah K -- Pereira-Leal, Jose B -- Nilsson, Daniel -- Peterson, Jeremy -- Salzberg, Steven L -- Shallom, Joshua -- Silva, Joana C -- Sundaram, Jaideep -- Westenberger, Scott -- White, Owen -- Melville, Sara E -- Donelson, John E -- Andersson, Bjorn -- Stuart, Kenneth D -- Hall, Neil -- AI045039/AI/NIAID NIH HHS/ -- AI45038/AI/NIAID NIH HHS/ -- AI45061/AI/NIAID NIH HHS/ -- R01 AI043062/AI/NIAID NIH HHS/ -- U01 AI040599/AI/NIAID NIH HHS/ -- U01 AI043062/AI/NIAID NIH HHS/ -- U01 AI045038/AI/NIAID NIH HHS/ -- U01 AI045039/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2005 Jul 15;309(5733):404-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Center Drive, Rockville, MD 20850, USA. nelsayed@tigr.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16020724" target="_blank"〉PubMed〈/a〉
