J Insect Physiol. 2012 Jul;58(7):941-8. doi: 10.1016/j.jinsphys.2012.04.010. Epub 2012 Apr 28.Three pheromone-binding proteins of Helicoverpa armigera were cloned and expressed in Escherichia coli. In order to characterize their physiological properties, ligand-binding experiments were performed using five biologically relevant substances including sex pheromones and interspecific signals. The results showed that one of the pheromone-binding proteins, HarmPBP1, binds strongly to each of the two principal pheromone components of H. Read More
