Function

PBP_BOMMO This major soluble protein in olfactory sensilla of male moths serves to solubilize the extremely hydrophobic pheromone molecules such as bombykol and to transport pheromone through the aqueous lymph to receptors located on olfactory cilia.

Publication Abstract from PubMed

The transport of hydrophobic insect pheromones through the aqueous medium surrounding their receptors is assisted by pheromone-binding proteins (PBPs). The protein from the silkworm moth Bombyx mori, BmorPBP, exhibits a pH-dependent conformational change postulated to trigger the release of the pheromone bombykol to its receptor. At low pH, an alpha-helix occupies the same binding pocket that houses the pheromone in the BmorPBP-bombykol complex at high pH. We have determined the crystal structure of apo BmorPBP at a resolution of 2.3 angstroms and pH 7.5, which has surprisingly a structure similar to the A-form. These data suggest that BmorPBP undergoes a ligand-dependent conformational change in addition to the previously described pH-dependent conformational change. Analysis of the alpha-helix occupying the binding pocket reveals an amphipathic helix with three acidic residues along one face that are conserved among lepidopteran PBPs and may be involved in a conformational transition of BmorPBP at the receptor membrane.
