Caractérisation in vitro et in vivo des enzymes de dégradation des odorants chez les insectes

, 2010
La communication phéromonale chez les insectes constitue un modèle de choix pour l étude des bases moléculaires de la réception olfactive. Sa spécificité serait assurée dès le niveau antennaire, par l intervention de protéines impliquées dans les ...

Degradation of pheromone and plant volatile components by a same Odorant-Degrading Enzyme in the cotton leafworm, Spodoptera littoralis

Background: Odorant-Degrading Enzymes (ODEs) are supposed to be involved in the signal inactivation step within the olfactory sensilla of insects by quickly removing odorant molecules from the vicinity of the olfactory receptors.

Insect chemosensory enzymes as new targets to disturb insect pestolfaction? A case study in Drosophila.

, 2017
De nombreux insectes s’avèrent être des ravageurs de culture, pouvant de surcroît transmettre des pathogènes aux plantes et ainsi causer des dégâts d’importance économique notables.

Characterization of an antennal carboxylesterase from the pest moth Spodoptera littoralis degrading a host plant odorant.

Background: Carboxyl/cholinesterases (CCEs) are highly diversified in insects. These enzymes have a broad range of proposed functions, in neuro/developmental processes, dietary detoxification, insecticide resistance or hormone/pheromone degradation.

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioural response dynamics to pheromone in Drosophila

Background: Insects respond to the spatial and temporal dynamics of a pheromone plume, which implies not only a strong response to"odor on", but also to"odor off". This requires mechanisms geared toward a fast signal termination.

Drosophila Melanogaster as a Model for Molybdo-Flavoenzyme Mediated Protection against Chemical and Physical Stress

Aldehyde oxidase (AO) and xanthine oxidoreductase (XOR) are molybdo-flavoenzymes (MFEs) involved in the oxidation of hundreds of endogenous and exogenous aldehydes and N-heterocyclic compounds many of which are drugs, vitamins and environmental ...
