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.

Stability and Dynamics of the Porcine Odorant-Binding Protein

Biochemistry, 2007
The denaturation process of porcine odorant-binding protein (pOBP) was studied by intrinsic fluorescence analysis and far- and near-UV circular dichroism measurements. Our results showed that a reversible one-step process described the denaturation by GdnHCl.

Structural and biochemical evaluation of Ceratitis capitata odorant‐binding protein 22 affinity for odorants involved in intersex communication

Insect molecular biology (Print), 2019
In insects, odorant‐binding proteins (OBPs) connect the peripheral sensory system to receptors of olfactory organs. Medfly Ceratitis capitata CcapObp22 shows 37% identity and close phylogenetic affinities with Drosophila melanogaster OBP69a/pheromone ...

Antennal transcriptome analysis of the maize weevil Sitophilus zeamais: Identification and tissue expression profiling of candidate odorant-binding protein genes.

Archives of Insect Biochemistry and Physiology, 2019
Our bioassays reviewed that antennae played crucial roles in the responses of maize weevil (Sitophilus zeamais) to food and sex volatiles. In order to identify the maize weevil odorant-binding protein (OBP) genes, we analyzed its antennal transcriptome ...

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).
