1. Comparative genomics of an endophytic Pseudomonas putida isolated from mango orchard
Abstract We analyzed the genome sequence of an endophytic bacterial strain Pseudomonas putida TJI51 isolated from mango bark tissues. Next generation DNA sequencing and short read de novo assembly generated the 5,805,096 bp draft genome of P. putida TJI51. Out of 6,036 protein coding genes in P. putida TJI51 sequences, 4,367 (72%) were annotated with functio

2. Mapeamento do potencial biossintético em linhagens de Streptomyces / Mapping the biosynthetic potential in Streptomyces strains
Actinobacteria are important sources of new molecules with biological activities. Streptomyces are the most important genera studied. Such microorganisms carries out among a variety of biosynthetic enzimes, two main groups known as polyketide synthase (PKS) and non ribosomal peptide synthetase (NRPS), both catalyzing the biosynthesis of polyketide and non ri

3. Identificação e validação de um novo alvo funcional de um peptídeo com atividade anti-hipertensiva do veneno da Bothrops jararaca / Identification and validation of a novel functional target of a peptide from Bothrops jararaca venom with antihypertensive activity
O BPP-10c é um decapeptídeo bioativo, rico em resíduos de prolina e é expresso em uma proteína precursora no cérebro e na glândula de veneno da Bothrops jararaca. Recentemente demonstramos que o BPP-10c tem um potente e sustentado efeito anti-hipertensivo em ratos espontaneamente hipertensos (SHR), sem, no entanto, causar qualquer efeito em ratos norm

4. Antimicrobial metabolites and siderophore produced by strains from Anthropogenic Dark Earth of the Occidental Amazon / "Produção de metabólitos antimicrobianos e sideróforos de isolados provenientes de Terra Preta Antropogênica da Amazônia Ocidental"
Os microrganismos atraem considerável atenção por serem uma fonte de compostos biotecnológicos e farmacêuticos. Diversos produtos naturais peptídicos produzidos por fungos e bactérias são sintetizados por grandes enzimas, conhecidas como peptídeo sintetase não ribossômica (NRPS) e policetídeo sintase (PKS). A bioprospecção dos microrganismos is

5. "Caracterização molecular de cianobactérias brasileiras e distribuição de genes de produtos naturais" / Molecular characterization of Brazilian cyanobacteria and distribution of natural products genes
O espaço intergênico (IGS) juntamente com suas subunidades flanqueadoras (cpcB) e (cpcA) do operon do ficocianina foi usado para identificar linhagens de cianobactérias. Dentro do domínio Bacteria somente as cianobactérias possuem o operon da ficocianina e a região cpcBA-IGS é suficientemente variável para diferenciar linhagens desses microrganismos.

6. The mycosubtilin synthetase of Bacillus subtilis ATCC6633: A multifunctional hybrid between a peptide synthetase, an amino transferase, and a fatty acid synthase
Bacillus subtilis strain ATCC6633 has been identified as a producer of mycosubtilin, a potent antifungal peptide antibiotic. Mycosubtilin, which belongs to the iturin family of lipopeptide antibiotics, is characterized by a β-amino fatty acid moiety linked to the circular heptapeptide Asn-Tyr-Asn-Gln-Pro-Ser-Asn, with the second, third, and sixth position p

7. The peptide synthetase gene phsA from Streptomyces viridochromogenes is not juxtaposed with other genes involved in nonribosomal biosynthesis of peptides.
By complementation of a previously described non-phosphinothricin tripeptide (PTT)-producing mutant, NTG1, which is blocked in nonribosomal synthesis of the peptide, a DNA fragment including the putative peptide synthetase gene phsA was isolated (W. Wohlleben, R. Alijah, J. Dorendorf, D. Hillemann, B. Nussbaumer, and S. Pelzer, Gene 115:127-132, 1992). Seque

8. Genetic dissection of protein–protein interactions in multi-tRNA synthetase complex
Cytoplasmic aminoacyl-tRNA synthetases of higher eukaryotes acquired extra peptides in the course of their evolution. It has been thought that these appendices are related to the occurrence of the multiprotein complex consisting of at least eight different tRNA synthetase polypeptides. This complex is believed to be a signature feature of metazoans. In this

9. Molecular Cloning of the Actinomycin Synthetase Gene Cluster from Streptomyces chrysomallus and Functional Heterologous Expression of the Gene Encoding Actinomycin Synthetase II
The actinomycin synthetases ACMS I, II, and III catalyze the assembly of the acyl peptide lactone precursor of actinomycin by a nonribosomal mechanism. We have cloned the genes of ACMS I (acmA) and ACMS II (acmB) by hybridization screening of a cosmid library of Streptomyces chrysomallus DNA with synthetic oligonucleotides derived from peptide sequences of t

10. Heterologous expression in Escherichia coli of the first module of the nonribosomal peptide synthetase for chloroeremomycin, a vancomycin-type glycopeptide antibiotic
The gene cluster from Amycolotopsis orientalis responsible for biosynthesis of the vancomycin-type glycopeptide antibiotic chloroeremomycin was recently sequenced, indicating that this antibiotic derives from a seven-residue peptide synthesized by a three-subunit (CepA, CepB, and CepC) modular nonribosomal peptide synthetase. Expression of all or parts of th

11. Peptide Mapping of Aminoacyl-tRNA Synthetases: Evidence for Internal Sequence Homology in Escherichia coli Leucyl-tRNA Synthetase
Most aminoacyl-tRNA synthetases contain polypeptide chains of about either 50,000 or 100,000 daltons. Peptide mapping of tryptic, chymotryptic, or Staphylococcus aureus acid protease digests of seryl-tRNA synthetase (100,000, dimer) and leucyl-tRNA synthetase (100,000, monomer) from E. coli was done after selective modification of lysine residues with [14C]s

12. Peptide Synthetase Gene in Trichoderma virens
Trichoderma virens (synonym, Gliocladium virens), a deuteromycete fungus, suppresses soilborne plant diseases caused by a number of fungi and is used as a biocontrol agent. Several traits that may contribute to the antagonistic interactions of T. virens with disease-causing fungi involve the production of peptide metabolites (e.g., the antibiotic gliotoxin a
