Welcome to TPS !

Trehalose is a non-reducing disaccharide of glucose that increases under abiotic stress in organisms. Previous studies have found trehalose, for instance, to participate in the responses of microorganism, especially bacteria and yeast to different abiotic stresses. Trehalose can protect plant cytomembranes against both drought injuries and freezing injuries and maintain the stability of enzymes. Trehalose-6-P synthase (TPS) catalyzes the conversion of Glc-6-P and UDP-Glc into trehalose-6-P (T-6-P). T-6-P is then catalyzed by T-6-P phosphatase (TPP) and releases trehalose. Both plants and yeast (Saccharomyces cerevisiae) share a similar biosynthesis pathway. T-6-P could restrict glucose influx by its interaction with sugar kinase activities and glucose transport.
