Odorant binding initially occurring at the central pocket in bovine odorant-binding protein

Biochemical and Biophysical Research Communications, 2005
Why bovine odorant-binding protein (OBPb), among OBP family, assumes a dimeric structure has been unclear. Here we clarified, by measuring the fluorescence of intrinsic tryptophan and tyrosine residues of intact OBPb and OBPb whose C-terminal 10 amino acids were deleted, that odorant enters the central pocket formed by the dimerization when OBPb first ...

Sensilla localization and sex pheromone recognition of odorant binding protein OBP4 in the mirid plant bug Adelphocoris lineolatus (Goeze).

Journal of insect physiology, 2020
Pheromone binding proteins (PBPs) are well studied in lepidopteran moths and are considered to be crucial in detection of sex pheromones as well as some green leaf volatiles.

Mechanistic exploration of odorant binding protein-mediated chlorpyrifos resistance in Nilaparvata lugens: Insights from insecticide sequestration and transcriptional regulation.

International Journal of Biological Macromolecules
The effectiveness and sustainable application of insecticides are severely threatened by the rapid evolution of resistance in agricultural pests. Recent research indicates that odorant binding proteins (OBPs) may be involved in facilitating insecticide ...

Odorant-Binding Proteins

Critical Reviews in Biochemistry and Molecular Biology, 1994
Odorant-binding proteins (OBPs) are low-molecular-weight soluble proteins highly concentrated in the nasal mucus of vertebrates and in the sensillar lymph of insects. Their affinity toward odors and pheromones suggests a role in olfactory perception, but their physiological function has not been clearly defined.

Key site residues of Cnaphalocrocis medinalis odorant-binding protein 13 CmedOBP13 involved in interacting with rice plant volatiles.

International Journal of Biological Macromolecules
Odorant binding proteins (OBPs) play key roles in the insect olfactory system by assisting the neuronal response to hydrophobic odor molecules, understanding their interaction with ligands will facilitate the virtual screening of behaviorally active ...

Analyses of structural dynamics revealed flexible binding mechanism for the Agrilus mali odorant binding protein 8 towards plant volatiles.

Pest Management Science, 2020
BACKGROUND Volatiles from host plants are an important source of insect pest attractants and repellents. Insect odorant binding proteins (OBPs) have been widely characterized, but the molecular binding dynamics and underlying mechanisms are still not ...

Expression and functional characterization of odorant‐binding protein genes in the endoparasitic wasp Cotesia vestalis

Insect Science, 2020
Odorant‐binding proteins (OBPs) are crucial in insect's olfactory perception, which participate in the initial step of odorant molecules transporting from the external environment to olfactory receptor neurons.

Electrochemical biosensing with odorant binding proteins

2020
The development of sensors that mimic the natural smell sensing mechanism and selectively recognizes the odorants remains highly challenging. Electrochemical based sensing approaches aiming at monitoring molecular recognition events between surface receptors and analytes in solution or in the gas phase, are one possible transduction platforms among ...

Deswapping bovine odorant binding protein

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2008
The X-ray structure of bovine Odorant Binding Protein (bOBP) revealed its association as a domain swapped dimer. bOBP, devoid of any cysteines, contrasts with other mammalian OBPs, which are monomeric and possess at least one disulfide bridge. We have produced a mutant of bOBP in which a glycine residue was inserted after position 121.
