Predicted structure of odorant-binding protein 12 from Monochamus alternatus (Hope) suggests a mechanism of flexible odorant-binding.

International Journal of Biological Macromolecules, 2023
Odorant-binding proteins (OBPs) are thought to bind and deliver hydrophobic odorants from the environment to receptors on insect sensory neurons, and have been used to screen behaviorally active compounds of insects.

Bioelectrical Nose Platform Using Odorant-Binding Protein as a Molecular Transporter Mimicking Human Mucosa for Direct Gas Sensing.

ACS Sensors, 2022
Recently, various bioelectronic nose devices based on human receptors were developed for mimicking a human olfactory system. However, such bioelectronic nose devices could operate in an aqueous solution, and it was often very difficult to detect ...

An odorant-binding protein of Asian citrus psyllid, Diaphorina citri, participates in the response of host plant volatiles.

Pest Management Science, 2021
BACKGROUND Odorant-binding proteins (OBPs) in insects contribute to the sensitivity of the olfactory system and function to connect external odorants to olfactory receptor neurons. Determination of the chemosensory functions in Diaphorina citri, a vector

Odorant‐binding proteins of mammals

Biological Reviews, 2021
ABSTRACTOdorant‐binding proteins (OBPs) of vertebrates belong to the lipocalin superfamily and perform a dual function: solubilizing and ferrying volatile pheromones to the olfactory receptors, and complexing the same molecules in specialized glands and assisting their release into the environment.

CRISPR/Cas9 mutagenesis abolishes odorant-binding protein BdorOBP56f-2 and impairs the perception of methyl eugenol in Bactrocera dorsalis (Hendel).

Insect Biochemistry and Molecular Biology, 2021
Olfaction underpins many insect behaviors, such as foraging, host location, mating, and predator avoidance. In the first step of insect olfaction, odorant-binding proteins (OBPs) bind hydrophobic odorants and transport them to odorant receptors.

Odorant binding protein C12 is involved in the defense against eugenol in Tribolium castaneum.

Pesticide Biochemistry and Physiology, 2021
Tribolium castaneum (T. castaneum) is a worldwide pest of stored grain that mainly harms flour, and not only causes serious loss of flour quality but also leads to deterioration of flour quality.

Mammalian odorant binding proteins

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 2000
Odorant binding proteins (OBPs) pertain to one of the most abundant classes of proteins found in the olfactory apparatus. OBPs are a sub-class of lipocalins, defined by their property of reversibly binding volatile chemicals, that we call 'odorants'. Numerous sequences of OBPs are now available, derived from protein sequencing from nasal mucus material,

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 in insects

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
This paper reviews the characteristics of pheromone and odorant-binding proteins (OBP) in insects, with particular reference to Lepidoptera. They are small (15 kDa) soluble proteins, very concentrated in the lymph of chemosensory sensilla and belonging to two major classes, pheromone-binding proteins (PBP) and general odorant-binding proteins.

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 ...
