Enantiodifferential Approach for the Target Protein Detection of the Jasmonate Glucoside That Controls the Leaf Closure of Samanea saman.

The synthetic photoaffinity probe designed to mimic bioactive molecules is one of the powerful tools for the identification of the target protein in living organisms. However, nonspecific interaction between the probe and nontargets would cause a misleading result in many cases of the photoaffinity labeling. In this chapter, we describe an enantiodifferential approach as a reliable method for the detection of the specific target protein of the bioactive natural product, jasmonate glucoside, a chemical factor that controls the nyctinastic leaf movement of the leguminous plants.
