[Fri-P2-105] Deciphering the ligand binding properties of the mouse odorant-binding protein OBP5 from Mus musculus

International audience; Odorant-binding proteins (OBPs) are abundant soluble proteins secreted in the nasal mucus of a variety of species which are believed to be involved in the transport of odorants towards olfactory receptors. In this study, we report the functional characterization of mouse OBP5 (mOBP5). mOBP5 was recombinantly expressed as a hexahistidine-tagged protein in bacteria and purified by metal affinity. Oligomeric state and secondary structure composition of mOBP5 was investigated using gel filtration and circular dichroism spectroscopy. Fluorescent experiments revealed that mOBP5 interacts with the fluorescent probe N-phenyl naphthylamine (NPN) with a micromolar affinity. Co…
