1. Alternative splicing originates different domain structure organization of Lutzomyia longipalpis chitinases
BACKGROUND The insect chitinase gene family is composed by more than 10 paralogs, which can codify proteins with different domain structures. In Lutzomyia longipalpis, the main vector of visceral leishmaniasis in Brazil, a chitinase cDNA from adult female insects was previously characterized. The predicted protein contains one catalytic domain and one chiti

2. A broad pH range and processive chitinase from a metagenome library
Chitinases are hydrolases that degrade chitin, a polymer of N-acetylglucosamine linked β(1-4) present in the exoskeleton of crustaceans, insects, nematodes and fungal cell walls. A metagenome fosmid library from a wastewater-contaminated soil was functionally screened for chitinase activity leading to the isolation and identification of a chitinase gene nam

3. 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

5. 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

6. Propriedades BioquÃmicas e Funcionais de uma ProteÃna Ligante à Quitina Purificada de Sementes de Moringa oleifera Lamarck / Biochemical and Functional Properties of Chitin-Binding Protein Purified from seeds of Moringa oleifera Lamarck
Moringa oleifera Lam. à uma planta originÃria do Noroeste da Ãndia, bem adaptada Ãs regiÃes tropicais. De suas sementes foi isolada uma nova proteÃna ligante à quitina, a Mo-CBP3, com propriedades coagulantes e atividade antifÃngica contra o fitopatÃgeno Fusarium solani. As proteÃnas foram extraÃdas da farinha delipidada de sementes com o tampÃo

7. 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

8. Characterization of chitinase gene from lutzomyia longipalpis:alternative splicing description and search for promoter sequence / Caracterização de gene de quitinase de Lutzomyia longipalpis: descrição de processamento alternativo e busca por seqüência promotora
Leishmaniasis is a disease caused by Leishmania protozoa transmitted by the bite of infected sand flies. Current methods used to combat this illness have been shown to be inefficient, and better knowledge of aspects related to Leishmania-sand fly interaction are necessary for the development of new controlling methods. A cDNA codifying for a midgutspecific c

9. 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

10. Cloning of the Bacillus thuringiensis serovar sotto chitinase (Schi) gene and characterization of its protein
Chitinase plays a positive role in the pathogenicity of Bacillus thuringiensis to insect pests. We used touchdown PCR to clone the chitinase (Schi) gene from Bacillus thuringiensis serovar sotto (Bt sotto) chromosomal DNA. Our DNA sequencing analysis revealed that the Bt sotto Schi gene consists of an open reading frame (ORF) of 2067 nucleotides with codes f

12. Identification of a Chitin-Binding Protein Secreted by Pseudomonas aeruginosa
One of the major proteins secreted by Pseudomonas aeruginosa is a 43-kDa protein, which is cleaved by elastase into smaller fragments, including a 30-kDa and a 23-kDa fragment. The N-terminal 23-kDa fragment was previously suggested as corresponding to a staphylolytic protease and was designated LasD (S. Park and D. R. Galloway, Mol. Microbiol. 16:263–270,
