Odorant‐Binding Proteins: Structural Aspects

Annals of the New York Academy of Sciences, 1998
ABSTRACT: Structural data on odorant‐binding proteins (OBPs), both in vertebrates and in insects, are reviewed and discussed. OBPs are soluble proteins interacting with odor molecules and Pheromones in the perireceptor areas, the nasal mucus in vertebrates and the sensillar lymph in insects.

Binding of selected odorants to bovine and porcine odorant-binding proteins

Chemical Senses, 1993
Twenty floral smelling tetrahydropyranyl and tetrahydrofuranyl ethers, and 12 additional compounds with different odours were used in ligand-binding experiments with purified 19 kDa bovine OBP and 22 kDa porcine OBP. Most of the odorants examined were found to be good ligands for both proteins, with dissociation constants in the micromolar range; the ...

Exploring the functional profiles of odorant binding proteins crucial for sensing key odorants in the new leaves of coconut palms in Rhynchophorus ferrugineus.

International Journal of Biological Macromolecules
The red palm weevil (RPW), Rhynchophorus ferrugineus (Curculionidae; Coleoptera) is a highly destructive global pest of coconut trees, with a preference for laying its eggs on new leaves.

Different binding properties of two general-odorant binding proteins in Athetis lepigone with sex pheromones, host plant volatiles and insecticides.

Pesticide Biochemistry and Physiology, 2020
Athetis lepigone (Alep) is a polyphagous pest native to Europe and Asia that has experienced major outbreaks in the summer maize area of China since 2011 and has shown evidence of resistance to some insecticides.

Odorant-binding proteins of the mouse

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
After the isolation of two odorant-binding proteins (OBP-I and OBP-II) from mouse nasal tissue, we have purified two additional OBPs, which bind tritiated 2-isobutyl-3-methoxypyrazine. OBP-III is a homodimer with subunits of M(r) 22,000 and pI 4.2. OBP-IV is a homodimer with subunits of M(r) 21,000 and pI 4.85.

Odorant binding proteins and chemosensory proteins potentially involved in host plant recognition in the Asian citrus psyllid, Diaphorina citri.

Pest Management Science, 2020
BACKGROUND Odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) are two families of small water-soluble proteins, which are involved in odor detection and subsequent signal transmission.

DyBOBS: A Dynamic Biomimetic Assay for Odorant-Binding to Odor-Binding Protein

Chemosensory Perception, 2010
An in vitro system was developed to mimic the structural and flow conditions of the human olfactory epithelium and to measure the dynamics of odorant-binding to odor-binding protein (OBP). A hydrophilic fused silica capillary, coated internally with a thin (about 1.3 µm) aqueous film of recombinant rat-OBP3 mimicked the human olfactory epithelium ...

Odorant binding proteins of Heliothis virescens

Insect Biochemistry and Molecular Biology, 1993
cDNA clones coding for three different binding proteins were isolated from an antennal library of Heliothis virescens. The deduced amino acid sequences showed only moderate homology to each other but shared several common structural features. Based on a comparison with the predicted primary structures of antennal binding proteins from different moth ...

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 ...

Subtypes of odorant‐binding proteins

European Journal of Biochemistry, 1998
Odorant‐binding proteins (OBP) in the mucus of the olfactory epithelium are thought to transfer the hydrophobic odorous compounds through the aqueous barrier towards the chemo‐sensory cells. To evaluate their binding properties, two distinct OBP subtypes of the rat were expressed as N‐terminal His‐tagged fusion proteins in Escherichia coli, thus ...
