Malaria parasite chitinase and penetration of the mosquito peritrophic membrane.
Malaria parasites (ookinetes) appear to digest the peritrophic membrane in the mosquito midgut during penetration. Previous studies demonstrated that lectins specific for N-acetylglucosamine bind to the peritrophic membrane and proposed that the membrane contains chitin [Rudin, W. & Hecker, H. (1989) Parasitol. Res. 75, 268-279]. In the present study, we show that the peritrophic membrane is di...
متن کاملIdentification and Molecular Characterization of a Chitin Deacetylase from Bombyx mori Peritrophic Membrane
The insect midgut epithelium is generally lined with a unique chitin and protein structure, the peritrophic membrane (PM), which facilitates food digestion and protects the gut epithelium. PM proteins are important determinants for PM structure and formation. In this study, the silkworm Bombyx mori midgut PM protein BmCDA7 was identified by proteomic tools. The full-length BmCDA7 cDNA is 1357 b...
متن کاملA New Type I Peritrophic Membrane Protein from Larval Holotrichia oblita (Coleoptera: Melolonthidae) Binds to Chitin
Peritrophic membranes (PMs) are composed of chitin and protein. Chitin and protein play important roles in the structural formation and function of the PM. A new type I PM protein, HoCBP76, was identified from the Holotrichia oblita. HoCBP76 was shown as a 62.3 kDa protein by SDS-PAGE analysis and appeard to be associated with the PM throughout its entire length. In H. oblita larvae, the midgut...
متن کاملIdentification of a new peritrophic membrane protein from larval Holotrichia parallela (Coleoptera: Motschulsky).
Peritrophic membranes (PMs) are composed of proteins, proteoglycans and chitin that play important roles in the structural formation and function of the PM. This study identified and characterized a new chitin binding protein named HpCBP45 by immunoscreening of the Holotrichia parallela larvae midgut expression library. The predicted amino acid sequence indicates that it contains eight tandem ch...
متن کاملSimulium pertinax Kollar. Six species in this subgenus are known from for the state of Mato Grosso (MT), Bra- zil (Simulium dekeyseri Shelley & Py-Daniel, Simulium friedlanderi Py-Daniel, S. pertinax, Simulium serranum Coscarón, Simulium spinibranchium Lutz and Simulium subpallidum
According to Adler and Crosskey (2011), three genera of Simuliidae occur in Brazil: Araucnephia Wygodzinsky & Coscarón, Lutzsimulium d’Andretta & d’Andretta (2 subgenera) and Simulium Latreille (8 subgenera). The subgenus Simulium (Chirostilbia) is represented by 13 species, all of which are found in Brazil, including one economically important species, the pest Simulium pertinax Kollar. Six sp...
