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 ...

Identification and characterization of odorant binding proteins in the diamondback moth, Plutella xylostella

Insect Science, 2020
Odorant binding proteins (OBPs) are a group of soluble proteins functioning as odorant carriers in insect antennae, mouth parts and other chemosensory organs.

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.

Highly sensitive and selective detection of human-derived volatile organic compounds based on odorant binding proteins functionalized silicon nanowire array

Sensors and Actuators B: Chemical, 2020
In this paper, we report the real-time, ultrasensitive, reproducible detection of volatile odorant molecules emitted by human based on free-standing silicon nanowire (SiNW) array functionalized with Anopheles gambiae odorant binding protein (AgOBP ...

Functional characterization of odorant-binding proteins from the scarab beetle Holotrichia oblita based on semiochemical-induced expression alteration and gene silencing.

Insect Biochemistry and Molecular Biology, 2019
With the advent of next-generation sequencing, it is now possible to rapidly identify the entire repertoire of olfactory genes likely to be involved in chemical communication of an insect species.

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 ...

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
