Odorant Binding to Bovine Odorant Binding Protein Detected by Intrinsic Fluorescence

Chemistry Letters, 2005
Abstract Odorant binding to bovine odorant binding protein (OBPb) made OBPb structure a little tighter and odorant detection by intrinsic fluorescence possible. For odorant with high affinity such as 3,7-dimethyl-1-octanol (DMO), the binding reaction proceeded in a two-step manner that inferred an existence of a third binding site.

The molecular identification, odor binding characterization, and immunolocalization of odorant-binding proteins in Liriomyza trifolii

Pesticide Biochemistry and Physiology, 2022
The Liriomyza trifolii is a highly invasive polyphagia pest. Understanding the physiological functions of odorant binding proteins (OBPs) in the chemical communication of L. trifolii can lead to effective pest management strategies. Seven full-length OBPs were identified by transcriptome screening of L. trifolii adults.

Molecular cloning of putative odorant-binding and odorant-metabolizing proteins

Biochemistry, 1991
Olfactory reception occurs via the interaction of odorants with the chemosensory cilia of the olfactory receptor cells located in the nasal epithelium. The cDNA clones from mRNA specific to olfactory mucosa were studied. One of these clones, OBPII, encodes a secretory protein with significant homology to odorant-binding protein (OBP), a protein with ...

Immunocytochemistry of Odorant-Binding Proteins

1994
Odorant-binding proteins are small water-soluble proteins that have been detected in the perireceptor compartment of olfactory receptor cells of vertebrates and insects [1,2]. Although their definite physiological role in olfaction is still unclear, similar functions have been proposed in stimulus transport or inactivation [1–6].

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 ...

Evolution and functional analysis of odorant-binding proteins in three rice planthoppers: Nilaparvata lugens, Sogatella furcifera, and Laodelphax striatellus.

Pest Management Science, 2019
BACKGROUND The white-backed planthopper (WBPH) Sogatella furcifera, the brown planthopper (BPH) Nilaparvata lugens, and the small brown planthopper (SBPH) Laodelphax striatellus are three notorious rice pests that cause annual losses in rice yield ...

Molecular characterization and volatile binding properties of pheromone binding proteins and general odorant binding proteins in Conogethes pinicolalis (Lepidoptera: Crambidae).

International Journal of Biological Macromolecules, 2020
Conogethes pinicolalis (Lepidoptera: Crambidae), a major pine pest, possesses a sensitive olfactory system to locate its host. Pheromone binding proteins (PBPs) and general odorant binding proteins (GOBPs) are two types of proteins involved in the ...
