Gladius and its derivatives as potential biosorbents for marine diesel oil
(2017-10-01)
The demand for low cost and effective materials to remove contaminants such as residues of oil spills has encouraged studies on new biosorbents produced from wastes. Considering the overgeneration of fishing residues and ...
Inhibitors of the fungal cell wall. Synthesis of 4-aryl-4-N-arylamine-1- butenes and related compounds with inhibitory activities on β(1-3) glucan and chitin synthases
(Pergamon-Elsevier Science Ltd, 2000-04)
As part of our project devoted to the search for antifungal agents, which act via a selective mode of action, we synthesized a series of new 4- aryl- or 4-alkyl-N-arylamine-1-butenes and transformed some of them into 2- ...
Expression and efficient secretion of a functional chitinase from Chromobacterium violaceum in Escherichia coli
(BioMed CentralLondon, 2013-06)
Background: Chromobacterium violaceum is a free-living β-proteobacterium found in tropical and subtropical regions. The genomic sequencing of C. violaceum ATCC 12472 has revealed many genes that underpin its adaptability ...

Clasificación molecular y análisis estructural de las quitinas sintasas
(2019-09-03)
RESUMEN: La quitina es un polímero compuesto por monómeros de N-acetilglucosamina unidos por enlaces β-1,4, su síntesis es catalizada por una familia de enzimas llamadas quitinas sintasas (CHS). Las CHS han sido clasificadas ...
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)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em BioquímicaBioquímica; Biologia Molecular, 2009-02-06)
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 ...
