an increase in the concentration of NaCl from 0 to 100 mM leads to a decrease in the OtsA activity by more than 35% when ADP-glucose or TDP-glucose is the substrate. When UDP-glucose or GDP-glucose is used as substrate, the OtsA activity is increased by 10–30%

Chondroitin
-
stimulation, particularly when a pyrimidine glucose nucleotide is used, rather than a purine glucose nucleotide
glycosyltransferase
the Thermoproteus tenax trehalose-6-phosphate synthase/phosphatase (TPSP) exhibits high phosphatase activity, but requires activation by the co-expressed glycosyltransferase for bifunctional synthase/phosphatase activity. The glycosyltransferase mediated activation of trehalose-6-phosphate synthase activity relies on the fusion of both, trehalose-6-phosphate synthase and trehalose-6-phosphate phosphatase domain, in the TPSP enzyme. Activation is mediated by complex-formation in vivo

dependence on polyanion concentrations for optimum TPS activity, overview
-
additional information
-
when pyrimidine sugar nucleotides are used as substrates, there is an almost absolute requirement for a high molecular weight polyanion for activity. When the purine sugar nucleotides are used as substrates fairly good enzymatic activity is observed in absence of a polyanion, this activity increases 2 to 4fold in the presence of optimum concentrations of polyanion. Activation by the polyanion is inhibited by high salt concentrations as well as by high concentrations of mononucleoside phosphates

expression of TPS1 driven by the ABI3 promoter rescues the severe embryo phenotype but not the vegetative phenotype of tps1. tps1 exhibits a severe phenotype in vegetative tissue, consistent with the role played in embryo development

tps1DELTA mutants fail to complete embryogenesis and rescued lines have stunted growth and delayed flowering. Loss of trehalose 6-phosphate production might not be the only reason for the growth defects of Arabidopsis thaliana tps1 mutants

stress hypersensitivity of mutants deleted for gene TPS1. At 42°C, the viability of the tps1DELTA mutant sharply drops by several decades, whereas the viability of the wild-type TPS1 strain remains almost unchanged. The the mal- BY4741 strain is unable to import trehalose. Overview of the impact of the different stresses on the drop of viability in wild-type and mdeletion mutants. The tps1DELTA mutant rapidly loses its ATP content in response to heat shock at 42°C
malfunction

physiological function
-
disruption of the TPS2 gene encoding the only trehalose 6-phosphate phosphatase activity in Candida albicans causes a pleiotropic defective phenotype, maintaining the cell wall integrity and the ability to form chlamydospores. A homozygous tps2Delta/tps2Delta shows reduced growth at high temperatures and a marked sensitivity to heatshock and severe oxidative exposure. Exponential tps2Delta null cells display an adaptive response to oxidative stress as well as cross-tolerance between temperature and oxidative stress. Differential measurement of trehalose and trehalose 6-phosphate, revealed a significant accumulation of trehalose 6-phosphate in tps2Delta cells, which is enhanced after oxidative exposure. The level of trehalose 6-phosphate in parental cells is virtually undetectable, and oxidative treatment only induces the synthesis of free trehalose
physiological function

Tps1 functions as a sugar sensor to integrate carbon and nitrogen metabolism and regulate a subset of primary and secondary metabolic pathways, such as the oxidative pentose phosphate pathway and pigment formation, respectively, during plant colonization, allowing the fungus to adapt to the nutritional and redox conditions encountered in the plant cell and establish disease. Tps1 regulates gene expression via the modulation of NADPH. Tps1 also regulates Nmr activity, involved in nitrogen metabolism, mechanism, overview
physiological function
-
the TPS1 protein is a key regulator of trehalose metabolism throughout the Arabidopsis life cycle and not just in embryo development, it plays a key role in modulating trehalose 6-phosphate levels in vegetative tissues of Arabidopsis thaliana
physiological function
the fused trehalose-6-phosphate synthase/phosphatase TPSP consists of an N-terminal trehalose-6-phosphate synthase (TPS) and a C-terminal trehalose-6-phosphate phosphatase (TPP) domain. The gene is organized in an operon with a putative glycosyltransferase GT and a putative mechanosensitive channel MSC. The enzyme exhibits high phosphatase activity, but requires activation by the co-expressed GT for bifunctional synthase-phosphatase activity. The GT mediated activation of trehalose-6-phosphate synthase activity relies on the fusion of both, trehalose-6-phosphate synthase and trehalose-6-phosphate phosphatase domain, in the enzyme. Activation is mediated by complex-formation
physiological function
-
enzyme TPS1 is important throughout the life cycle with At least three catalytically active TPS isoforms
physiological function
isozyme OstA2 mainly contributes to the trehalose pool of strain 1CP; isozyme OtsA1 seems to be involved in the overproduction of trehalose lipids
physiological function
in fungi, trehalose-6-phosphate synthase 1 plays a key role in the biosynthesis of trehalose
physiological function
-
the Tps1 protein is essential to maintain ATP levels during heat shock. Tps1 is endowed with a regulatory function in energy homeostasis, which is essential to withstand adverse conditions and maintain cellular integrity. Tps1, not trehalose, is important for yeast viability in response to various kinds of stresses. Contribution of the Tps1 protein to thermotolerance and acquired thermotolerance, enzyme deletion mutants show highly reduced growth at 42°C in contrast to the wild-type enzyme
physiological function
-
possible signaling role of trehalose-6-phosphate or trehalose in the dessication process, sugars are proposed to play a role in osmotic adjustment, to stabilize biomolecules and membranes, and to act as a replacement for water
physiological function
the enzyme functions as a cytoskeletal element regulating cell morphology
physiological function
-
regulation of OtsA expression during cold shock, both low temperature and accumulation of trehalose can inhibit OtsA expression, overview
-
physiological function
-
the multifunctional protein, OtsA, is indispensable for bacterial survival in various environments. The catalytic efficiency of OtsA is affected by its N-loop at low temperatures. The flexibility of the OtsA N-loop is related to the growth temperature of the respective bacterial species
