1. Heterologous Expression of a Putative ClpC Chaperone Gene Leads to Induction of a Host Metabolite
Genome mining provides exciting opportunities for the discovery of natural products. However, in contrast to traditional bioassay-guided approaches, challenges of genome mining include poor or no expression of biosynthetic gene clusters (BGCs). Additionally, given that thousands of BGCs are now available through extensive genome sequencing, how does one sele

2. Filogenia molecular de Toxoplasmatinae: comparação entre inferências baseadas em sequências genéticas mitocondriais e de apicoplasto
Resumo A filogenia da subfamília Toxoplasmatinae tem sido amplamente investigada com diversos marcadores moleculares. Neste estudo, a filogenia molecular da subfamília Toxoplasmatinae foi analisada através de genes de apicoplasto e mitocondriais. Foram analisadas sequências parciais de genes de apicoplasto codificadores da protease caseinolítica (clpC),

3. Considerações sobre as recomendações da Comissão de Limites da Plataforma Continental sobre o cone do Amazonas
Em 2004, o Brasil submeteu à Comissão de Limites da Plataforma Continental (CLPC) uma proposta para o limite exterior da plataforma continental brasileira para extensão além das 200 milhas náuticas. Em 2007, a CLPC apresentou suas recomendações; no entanto, não recomendou quatro áreas propostas pelo Brasil, entre elas o Cone do Amazonas. O objetivo

4. O novo pleito brasileiro no mar: a plataforma continental estendida e o Projeto Amazônia Azul
O presente estudo analisa a submissão do Brasil a uma plataforma continental estendida formulada à Comissão de Limites da Plataforma Continental (CLPC). Primeiramente, o trabalho apresenta a evolução dos limites marítimos brasileiros ao longo de sua formação histórica até o momento atual. Posteriormente, examina o conceito jurídico de plataforma c

5. Filogenia molecular de protozoários pertencentes à sub-família Toxoplasmatinae pela análise de genes mitocondriais e de apicoplasto / Molecular phylogeny in protozoan of the subfamily toxoplasmatinae based on genes of mitocôndria and apicoplasto
Os membros da sub-família Toxoplasmatinae conhecidos são Hammondia hammondi, Toxoplasma gondii, Neospora hughesi, Neospora caninum, Hammondia heydorni e Besnoitia spp. Os cães (e provavelmente outras espécies de canídeos) são hospedeiros definitivos de N. caninum e H. heydorni. Os oocistos destas espécies de coccídios são morfologicamente indistingu

6. Molecular phylogeny and comparative genomics of Gram- positive bacteria of the gastrointestinal tract / Filogenia molecular e genômica comparativa de bactérias Grampositivas do trato gastrointestinal
Recent information on the complete genome of probiotic lactic acid bacteria and Listeria monocytogenes, and the elucidation on those caused on large clusters of virulence genes, denominated pathogenicity islands (PAIs) present in L. monocytogenes, have brought the attention to the likely existence of gene sequences common to both groups, probiotic and entero

7. Obtention and caracterization of cassava leaves protein concentrated with differents trataments. / ObtenÃÃo e caracterizaÃÃo de concentrado proteico de folhas de mandioca submetido a diferentes tratamentos.
All over the world the socioeconomic differences restrict population access to animal proteins. The cassava leaves are researched to substitute conventional foods, because its proteins, vitamins and minerals content are relatively high, besides its low cost and availability. However, due to the high content of fibers and the presence of antinutritive substan

8. MecA, an adaptor protein necessary for ClpC chaperone activity
ClpC of Bacillus subtilis is an ATP-dependent HSP100/Clp protein involved in general stress survival. A complex of ClpC with the protease ClpP and the adaptor protein MecA also controls competence development by regulated proteolysis of the transcription factor ComK. We investigated the in vitro chaperone activity of ClpC and found that the presence of MecA

9. The First Gene of the Bacillus subtilis clpC Operon, ctsR, Encodes a Negative Regulator of Its Own Operon and Other Class III Heat Shock Genes
The Bacillus subtilis clpC operon is regulated by two stress induction pathways relying on either ςB or a class III stress induction mechanism acting at a ςA-like promoter. When the clpC operon was placed under the control of the isopropyl-β-d-thiogalactopyranoside (IPTG)-inducible Pspac promoter, dramatic repression of the natural clpC promoters fused to

10. Stress induction of clpC in Bacillus subtilis and its involvement in stress tolerance.
A member of the clpC subfamily of stress response-related Clp ATPases was cloned from Bacillus subtilis. The B. subtilis clpC gene was induced in response to various stresses, including heat shock. Its product was identified as a general stress protein (Gsp12) described previously. A dramatic increase in the amount of clpC mRNA immediately after exposure to

11. Inactivation of the clpC1 Gene Encoding a Chloroplast Hsp100 Molecular Chaperone Causes Growth Retardation, Leaf Chlorosis, Lower Photosynthetic Activity, and a Specific Reduction in Photosystem Content1
ClpC is a molecular chaperone of the Hsp100 family. In higher plants there are two chloroplast-localized paralogs (ClpC1 and ClpC2) that are approximately 93% similar in primary sequence. In this study, we have characterized two independent Arabidopsis (Arabidopsis thaliana) clpC1 T-DNA insertion mutants lacking on average 65% of total ClpC content. Both mut

12. Mutations in ClpC2/Hsp100 suppress the requirement for FtsH in thylakoid membrane biogenesis
The Arabidopsis var2 variegation mutant defines a nuclear gene for a chloroplast FtsH metalloprotease. Leaf variegation is expressed only in homozygous recessive plants. The cells in the green leaf sectors of this mutant contain morphologically normal chloroplasts, whereas cells in the white sectors contain abnormal plastids lacking organized lamellar struct
