trehalose-6-phosphate synthase; Trehalose-6-Phosphate Synthase (TPS, EC 2.4.1.15) is a glycosyltransferase that catalyses the synthesis of alpha,alpha-1,1-trehalose-6-phosphate from glucose-6-phosphate using a UDP-glucose donor. It is a key enzyme in the trehalose synthesis pathway. Trehalose is a nonreducing disaccharide present in a wide variety of organisms and may serve as a source of energy and carbon. It is characterized most notably in insect, plant, and microbial cells. Its production is often associated with a variety of stress conditions, including desiccation, dehydration, heat, cold, and oxidation. This family represents the catalytic domain of the TPS. Some members of this domain family coexist with a C-terminal trehalose phosphatase domain.

alpha,alpha-trehalose-phosphate synthase [UDP-forming]; This enzyme catalyzes the key, penultimate step in biosynthesis of trehalose, a compatible solute made as an osmoprotectant in some species in all three domains of life. The gene symbol OtsA stands for osmotically regulated trehalose synthesis A. Trehalose helps protect against both osmotic and thermal stresses, and is made from two glucose subunits. This model excludes glucosylglycerol-phosphate synthase, an enzyme of an analogous osmoprotectant system in many cyanobacterial strains. This model does not identify archaeal examples, as they are more divergent than glucosylglycerol-phosphate synthase. Sequences that score in the gray zone between the trusted and noise cutoffs include a number of yeast multidomain proteins in which the N-terminal domain may be functionally equivalent to this family. The gray zone also includes the OtsA of Cornyebacterium glutamicum (and related species), shown to be responsible for synthesis of only trace amounts of trehalose while the majority is synthesized by the TreYZ pathway; the significance of OtsA in this species is unclear (see Wolf, et al., ).

trehalose-phosphate phosphatase similar to Escherichia coli trehalose-6-phosphate phosphatase OtsB and Saccharomyces cerevisiae trehalose-phosphatase TPS2; Trehalose biosynthesis in bacteria is known through three pathways - OtsAB, TreYZ and TreS. The OtsAB pathway, also known as the trehalose 6-phosphate synthase (TSP)/ Trehalose-6-phosphate phosphatase (TPP) pathway, is the most common route known to be involved in the stress response of Escherichia coli. It involves converting glucose-6-phosphate and UDP-glucose to form trehalose-6-phosphate (T6P), catalyzed by TPS, the product of the otsA gene, this step is followed by the dephosphorylation of T6P to yield trehalose and inorganic phosphate, catalyzed by a specific TPP, the product of otsB gene. This OtsAB (or TSP/TPP) pathway, is also the most common route known to be involved in the stress response of yeast In Saccharomyces cerevisiae, the corresponding enzymes, TPS1p and TPS2p, form a multimeric synthase complex together with additional regulatory subunits encoded by Tsl1 and Tps3. Trehalose is a common disaccharide accumulated by organisms as a reservation of carbohydrate and in response to unfavorable growth conditions. This family belongs to the haloacid dehalogenase-like (HAD) hydrolases, a large superfamily of diverse enzymes that catalyze carbon or phosphoryl group transfer reactions on a range of substrates, using an active site aspartate in nucleophilic catalysis. Members of this superfamily include 2-L-haloalkanoic acid dehalogenase, azetidine hydrolase, phosphonoacetaldehyde hydrolase, phosphoserine phosphatase, phosphomannomutase, P-type ATPases and many others. HAD hydrolases are found in all three kingdoms of life, and most genomes are predicted to contain multiple HAD-like proteins. Members possess a highly conserved alpha/beta core domain, and many also possess a small cap domain, the fold and function of which is variable. HAD hydrolases are sometimes referred to as belonging to the DDDD superfamily of phosphohydrolases.
