  4. Metabolically engineered Escherichia coli for efficient production of glycosylated natural products

    Salvador Peirú; Eduardo Rodríguez; Hugo G. Menzella; John R. Carney; Hugo Gramajo; Ciencias Bioquímicas Y Farmacéuticas
    Significant achievements in polyketide gene expres-sion have made Escherichia coli one of the most promising hosts for the heterologous production of pharmacologically important polyketides. However, attempts to produce glycosylated polyketides, by the expression of heterologous sugar pathways, have been hampered until now by the low levels of glyco-sylated compounds produced by the recombinant hosts. By carrying out metabolic engineering of three endogenous pathways that lead to the synthesis of TDP sugars in E. coli, we have greatly improved the intracellular levels of the common deoxysugar intermediate TDP-4-keto-6-deoxyglucose resulting in increased production of the heterologous sugars TDP-L-mycarose and TDP-D-desosamine, both com-ponents...

    The increased speed and decreasing cost of sequencing, along with an understanding of the clinical relevance of emerging information for patient management, has led to an explosion of potential applications in healthcare. Cur-rently, SNP arrays and Next-Generation Sequencing (NGS) technologies are relatively new techniques used to scan genomes for gains and losses, losses of heterozygosity (LOH), SNPs, and indel variants as well as to perform com-plete sequencing of a panel of candidate genes, the entire exome (whole exome sequencing) or even the whole ge-nome. As a result, these new high-throughput technologies have facilitated progress in the understanding and diagnosis of...

    Plant cell wall is mainly composed by cellulose, hemicellulose and lignin. The heterogeneous struc-ture and composition of the hemicellulose are key impediments to its depolymerization and subse-quent use in fermentation processes. Thus, this study aimed to perform a screening of thermophilic and thermotolerant filamentous fungi collected from different regions of the São Paulo state, and ana-lyze the production of -xylosidase and arabinanase at different temperatures. These enzymes are im-portant to cell wall degradation and synthesis of end products as xylose and arabinose, respectively, which are significant sugars to fermentation and ethanol production. A total of 12 fungal species were analyzed...

    Propolis is a natural product widely used for humans. Due to its complex composition, a number of applications (antimicrobial, antiinflammatory, anesthetic, cytostatic and antioxidant) have been at-tributed to this substance. Using Saccharomyces cerevisiae as a eukaryotic model we investigated the mechanisms underlying the antioxidant effect of propolis from Guarapari against oxidative stress. Submitting a wild type (BY4741) and antioxidant deficient strains (ctt1, sod1, gsh1, gtt1 and gtt2) either to 15 mM menadione or to 2 mM hydrogen peroxide during 60 min, we observed that all strains, except the mutant sod1, acquired tolerance when previously treated with 25 g/mL of alco-holic...

  18. Técnica, ética y mejoramiento humano: acerca de la constitución tecno-lógica del ser

    Osorio García, Sergio Néstor; Macraigne ., Steve
    La comunicación presenta un avance de investigación del proyecto HUM 1517: la Bioética como ética de la responsabilidad planetaria, que indaga sobre un nuevo horizonte epistemológico para fundamentación de la Bioética tal y como fuera diseñada por el bioquímico norteamericana Van Rensselaer Potter. De allí se deriva un programa de fundamentación epistemológica que nos permite preguntarnos por el papel de la bioética en la perspectiva del mejoramiento técnico de la humanidad. El mejoramiento de la humanidad sólo se puede entender si tenemos en cuenta la esencia tecno-lógica del ser humano, y si aseguramos el objeto del mejoramiento: la supervivencia la...

  19. cereal seed development and germination

    O Domínguez; Francisco J. Cejudo; Paolo Sabelli; Francisco J. Cejudo; Bioquímica Vegetal Y Fotosíntesis
    The life cycle of cereal seeds can be divided into two phases, development and germination, separated by a quiescent period. Seed development and germination require the growth and differentiation of new tissues, but also the ordered disappearance of cells, which takes place by a process of programmed cell death (PCD). For this reason, cereal seeds have become excellent model systems for the study of developmental PCD in plants. At early stages of seed development, maternal tissues such as the nucellus, the pericarp, and the nucellar projections undergo a progressive degeneration by PCD, which allows the remobilization of their cellular contents...
