Molecular and functional characterization of three odorant‐binding proteins from the wheat blossom midge, Sitodiplosis mosellana

Insect Science, 2020
Sitodiplosis mosellana, a periodic but devastating wheat pest, relies on wheat spike volatiles as a cue in selecting hosts for oviposition. Insect odorant‐binding proteins (OBPs) are thought to play essential roles in filtering, binding and transporting ...

Odorant‐Binding Proteins: Expression and Function

Annals of the New York Academy of Sciences, 1998
ABSTRACT: Odorant‐binding proteins (OBPs) are a major constituent of the aqueous perireceptor compartment in vertebrates and in insects. Although different in primary structure, they are supposed to serve similar functions in both animal groups: (i) OBPs may act as solubilizers and carriers of the lipophilic odorants in the aqueous mucus or sensillum ...

Site-directed mutagenesis of odorant-binding proteins

2020
Modifying the affinity of odorant-binding proteins (OBPs) to small ligands by replacement of specific residues in the binding pocket may lead to several technological applications. Thanks to their compact and stable structures, OBPs are currently regarded as the best candidates to be used in biosensing elements for odorants and volatiles detection. The

Odorant-Binding Proteins from a Primitive Termite

Journal of Chemical Ecology, 2002
Hitherto, odorant-binding proteins (OBPs) have been identified from insects belonging to more highly evolved insect orders (Lepidoptera, Coleoptera, Diptera, Hymenoptera, and Hemiptera), whereas only chemosensory proteins have been identified from more primitive species, such as orthopteran and phasmid species.

Conformational Isomers of Insect Odorant-Binding Proteins

Archives of Biochemistry and Biophysics, 2002
We have identified and cloned the cDNAs encoding odorant-binding proteins (OBPs) from the large black chafer, Holotrichia parallela, and the yellowish elongate chafer, Heptophylla picea. Each species possess two OBPs, the proteins migrating faster in native gels (OBP1) showed high amino acid identity (>88%) to previously identified pheromone-binding ...

Mechanistic events underlying odorant binding protein chemoreception

Proteins: Structure, Function, and Bioinformatics, 2007
AbstractOdorant binding proteins (OBP's) are small hydrophilic proteins, belonging to the lipocalin family dedicated to bind and transport small hydrophobic ligands. Despite many works, the mechanism of ligand binding, together with the functional role of these proteins remains a topic of debate and little is known at the atomic level. The present work

Conformational Stability and Binding Properties of Porcine Odorant Binding Protein

Biochemistry, 1999
Apparently homogeneous odorant binding protein purified from pig nasal mucosa (pOBP) exhibited subunit molecular masses of 17 223, 17 447, and 17 689 (major component) Da as estimated by ESI/MS. According to gel filtration, this protein, its truncated forms, and/or its variants are homodimeric under physiologic conditions (pH 6-7, 0.1 M NaCl).

The chemoreceptors and odorant binding proteins of the soybean and pea aphids.

Insect Biochemistry and Molecular Biology, 2019
We examined the genome of the soybean aphid, Aphis glycines, and an updated genome assembly of the pea aphid, Acyrthosiphon pisum, for members of the three major families of chemoreceptors, the Odorant Receptors (ORs), Gustatory Receptors (GRs) and ...

Genome-wide identification and expression profiling of odorant-binding proteins in the oriental fruit fly, Bactrocera dorsalis.

Comparative Biochemistry and Physiology - Part D:Genomics and Proteomics, 2019
Olfaction contributes to many crucial behaviors in insects, such as foraging, locating hosts, mating, and avoiding predators. In the first step of the olfaction process in insects, odorant-binding proteins (OBPs) bind with the odorants and transport ...
