The GOBP2 of the moth Plutella xylostella binds with good affinity linear aldehydes, components of the sex pheromone of this species. By replacing two aromatic residues inside the binding pocket with leucine, the specificity of the protein can be switched from linear aldehydes to branched terpenoid compounds.
