1. Gelation of commercial pea protein isolate: effect of microbial transglutaminase and thermal processing
Abstract In the studied commercial pea protein isolate (PPI) some physicochemical modifications are induced in the protein structure during its processing. That fact would result into a reduction of proteins techno-functional properties. It has been evidenced by Differential Scanning Calorimetry the protein denaturation what gives as a result poor gelling ab

2. Identification of Albizia lebbeck seed coat chitin-binding vicilins (7S globulins) with high toxicity to the larvae of the bruchid Callosobruchus maculatus
Seed coat is a specialized maternal tissue that interfaces the embryo and the external environment during embryogenesis, dormancy and germination. In addition, it is the first defensive barrier against penetration by pathogens and herbivores. Here we show that Albizia lebbeck seed coat dramatically compromises the oviposition, eclosion and development of the

3. Efeito inseticida de vicilinas isoladas de sementes de erythrina velutina em condições de semi-campo para moscas das frutas (ceratitis capitata)
Vicilinas ligantes a quitina de sementes de Erythrina velutina, Canavalia ensiformis e Phaseoulus vulgaris foram isoladas através de procedimento que consistiu de precipitação com sulfato de amônio seguida de cromatografia de afinidade em coluna de quitina. O efeito dessas vicilinas sobre fêmeas adultas de Ceratitis capitata foi examinada por bioensaios

4. Determinação de motivos de ligação à quitina em vicilinas de Canavalia ensiformis e Vigna unguiculata através de métodos in silico e relação com suas toxicidades para o bruquídeo Callosobruchus maculatus (Coleoptera:Bruchidae)
Chitin is an important structural component of the cellular wall of fungi and exoskeleton of many invertebrate plagues, such as insects and nematodes. In digestory systems of insects it forms a named matrix of peritrophic membrane. One of the most studied interaction models protein-carbohydrate is the model that involves chitin-binding proteins. Among the in

5. Avaliação da ação bioinseticida de SBTI e vicilina de Erythrina velutina em enzimas digestivas e membrana peritrófica de larvas de Plodia interpunctella (Lepidoptera: Pyralidae)
Plodia interpunctella (Indian meal moth) is a cosmopolitan pest that attacks not only a wide range of stored grain as well other food products. Due to its economic importance several researches have focused in a method with ability to control this pest with few or no damage to the environment. The study of digestive enzymes inhibitors, lectins and chitin-bin

6. Cowpea Vicilins: Fractionation of Urea Denatured Sub-Units and Effects on Callosobruchus maculatus F. (Coleoptera: Bruchidae) Development
Vicilinas (globulinas de reserva 7S) isoladas de sementes de feijão-de-corda (Vigna unguiculata L.), susceptíveis (S) e resistentes (R) ao caruncho/gorgulho (Callosobruchus maculatus F., Coleoptera: Bruchidae) foram desnaturadas por uréia e fracionadas por cromatografia de troca iônica. As frações isoladas foram incorporadas em sementes artificiais par

7. Vicilins (7S storage globulins) of cowpea (Vigna unguiculata) seeds bind to chitinous structures of the midgut of Callosobruchus maculatus (Coleoptera: Bruchidae) larvae
The presence of chitin in midgut structures of Callosobruchus maculatus larvae was shown by chemical and immunocytochemical methods. Detection by Western blotting of cowpea (Vigna unguiculata) seed vicilins (7S storage proteins) bound to these structures suggested that C. maculatus-susceptible vicilins presented less staining when compared to C. maculatus-re

8. Identificação e caracterização parcial de albuminas e globulinas de tres cultivares brasileiros de Phascolus vulgaris
Seeds of Phaseolus vulgaris cv. Aeté-3, Coiano precoce and Carioca were analysed in different aspects: contents of the different protein fractions of albumins and globulins, electrophoretic banding patterns, amino acid composition, evaluation of the range of precipitaiton of major vicilins, and their nutritional values. The degree of glycosilation, carboydr

9. Characterization of a soybean beta-conglycinin-degrading protease cleavage site.
Protease C1, an enzyme from soybean (Glycine max [L.] Merrill cv Amsoy 71) seedling cotyledons, was previously determined to be the enzyme responsible for the initial degradation of the alpha' and alpha subunits, but not the beta subunit, of beta-conglycinin storage protein. The sizes of the proteolytic products generated by the action of protease C1 suggest

10. Proteomics of Medicago truncatula Seed Development Establishes the Time Frame of Diverse Metabolic Processes Related to Reserve Accumulation1
We utilized a proteomic approach to investigate seed development in Medicago truncatula, cv Jemalong, line J5 at specific stages of seed filling corresponding to the acquisition of germination capacity and protein deposition. One hundred twenty proteins differing in kinetics of appearance were subjected to matrix-assisted laser desorption ionization time of

11. Microbial Relatives of the Seed Storage Proteins of Higher Plants: Conservation of Structure and Diversification of Function during Evolution of the Cupin Superfamily
This review summarizes the recent discovery of the cupin superfamily (from the Latin term “cupa,” a small barrel) of functionally diverse proteins that initially were limited to several higher plant proteins such as seed storage proteins, germin (an oxalate oxidase), germin-like proteins, and auxin-binding protein. Knowledge of the three-dimensional stru

12. The three-dimensional structure of canavalin from jack bean (Canavalia ensiformis).
The three-dimensional structure of the vicilin storage protein canavalin, from Canavalia ensiformis, has been determined in a hexagonal crystal by x-ray diffraction methods. The model has been refined at 2.6 A resolution to an R factor of 0.197 with acceptable geometry. Because of proteolysis, 58 of 419 amino acids of the canavalin polypeptide are not visibl
