Abstract:

     Trehalose can be used as an energy source, plays an important role in stress tolerance and is found in bacteria, fungi, insects, invertebrates, plants and a large number of other organisms. Trehalose-6-phosphate synthase (TPS) is a key enzyme in trehalose synthesis that has been found and cloned in bacteria, fungi and plants but not in mammals. Trehalose is catalyzed in the fat body by trehalase synthase and trehalose-6-phosphatase (TPP) is the insect sugar. The protein sequences encoded by the TPS gene include two domains: TPS and TPP respectively, corresponding to the OtsA and OtsB genes in yeast. The discovery that TPS gene expression and enzyme activity changes are closely related to a number of physiological processes in insects which may lay the foundation for TPS as a new target for pest control.
