Structure of an antennally-expressed carboxylesterase suggests lepidopteran odorant degrading enzymes are broadly tuned [PDF]
Current Research in Insect Science, 2023 Insects rely on the detection of chemical cues present in the environment to guide their foraging and reproductive behaviour. As such, insects have evolved a sophisticated chemical processing system in their antennae comprised of several types of ...

Degradation of pheromone and plant volatile components by a same odorant-degrading enzyme in the cotton leafworm, Spodoptera littoralis. [PDF]
PLoS ONE, 2011 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.

An antennal carboxylesterase from Drosophila melanogaster, Esterase 6, is a candidate Odorant-Degrading Enzyme towards food odorants [PDF]
Frontiers in Physiology, 2015 Reception of odorant molecules within insect olfactory organs involves several sequential steps, including their transport through the sensillar lymph, interaction with the respective sensory receptors, and subsequent inactivation.

Antennae-enriched expression of candidate odorant degrading enzyme genes in the turnip aphid, Lipaphis erysimi [PDF]
Frontiers in Physiology, 2023 Aphids heavily rely on their olfactory system for foraging behavior. Odorant-degrading enzymes (ODEs) are essential in preserving the olfactory acuity of aphids by removing redundant odorants in the antennae.

Molecular basis for the behavioral effects of the odorant degrading enzyme Esterase 6 in Drosophila [PDF]
Scientific Reports, 2017 AbstractPrevious electrophysiological and behavioural studies implicate esterase 6 in the processing of the pheromone cis-vaccenyl acetate and various food odorants that affect aggregation and reproductive behaviours. Here we show esterase 6 has relatively high activity against many of the short-mid chain food esters, but negligible activity against ...

Antennal transcriptomic analysis of carboxylesterases and glutathione S-transferases associated with odorant degradation in the tea gray geometrid, Ectropis grisescens (Lepidoptera, Geometridae) [PDF]
Frontiers in Physiology, 2023 Introduction: Carboxylesterases (CXEs) and glutathione S-transferases (GSTs) can terminate olfactory signals during chemosensation by rapid degradation of odorants in the vicinity of receptors.

Research Progress of Insect Odorant Receptors
Guangdong nongye kexue, 2022 For insects, olfaction is an important signal input source for their behavioral perception. There are many kinds of proteins involved in the process of odor recognition, and they play a leading role in regulating feeding, swarming, mating, oviposition ...
