• Abstract

  Results obtained by enzyme directed evolution does not supress the need of exploration of new organisms as sources of enzymes and proteins with biotechnology applications. In this context, the phylum Artrhopoda has an amazing potencial to biomolecules prospection because it is the most diverse taxonomic group, including Arachnida. Arachnids are a group mainly studied due to spider and sco…

  Enzymology and molecular physiology in Arachnida, AP.R

• Abstract

  Arthropoda (main classes: Crustacea, Arachnida and Insecta) is the largest phylum representing 70% of all species already described. Besides that, this group is very important economically, including agriculture pests as well as harmful species to human, animal and plant health, being involved in the transmission of several diseases and with poisoning accidents. The digestive tract of art…

  Digestion in Arachnida and the control of proteolytic activity, AP.R

• Abstract

  Fucose residues are between the carbohydrates added to proteins in the post-translate modification process like the ones present at the antigens from the ABO blood group system and the Lewis antigens. Changes in the synthesis of the Lewis antigens and at the enzymes involved in Lewis antigens processing (fucosidases and fucosyltransferases, for example) were associated to cancer and metas…

  Fucose metabolism at Amblyomma sculptum (tick: Ixodidae): catalysis in fucosidases and fucose kinase, BP.IC

• Abstract

  Insects are the most important agriculture pests causing losses of approximately 15 billion dollars to global economy every year. Thus, it's necessary to develop new insect control strategies and insecticides. Spiders are insects predators and they have some insecticide molecules at their venoms. However, the use of new high throughput DNA and protein sequencing technics, allowed the iden…

  Characterization of insecticidal molecules produced at the digestive system from the spider Nephilingis cruentata and the effect at the development of Aedes aegypti, BP.IC

• Abstract

  Carbohydrates are diverse and complex molecules and are involved in many biological functions in living organisms. L-fucose is a constituent of many glycoconjugates synthesized by microorganisms, plants and animals. Glycoconjugates present on mammalian cell surface is related to a number of physiological and pathological processes including: cell-cell adhesion, cell differentiation, immun…
