trehalose-phosphatase; Trehalose, a neutral disaccharide of two glucose residues, is an important osmolyte for dessication and/or salt tolerance in a number of prokaryotic and eukaryotic species, including E. coli, Saccharomyces cerevisiae, and Arabidopsis thaliana. Many bacteria also utilize trehalose in the synthesis of trehalolipids, specialized cell wall constituents believed to be involved in the uptake of hydrophobic substances. Trehalose dimycolate (TDM, cord factor) and related substances are important constituents of the mycobacterial waxy coat and responsible for various clinically important immunological interactions with host organism. This enzyme, trehalose-phosphatase, removes a phosphate group in the final step of trehalose biosynthesis. The trehalose-phosphatase from Saccharomyces cerevisiae is fused to the synthase. At least 18 distinct sequences from Arabidopsis have been identified, roughly half of these are of the fungal type, with a fused synthase and half are like the bacterial members having only the phosphatase domain. It has been suggested that trehalose is being used in Arabidopsis as a regulatory molecule in development and possibly other processes. [Cellular processes, Adaptations to atypical conditions]

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.

It would appear that the two equivalent genes in the E. coli otsBA operon otsA the trehalose-6-phosphate synthase and otsB trehalose-phosphatase (this family) have undergone gene fusion in most eukaryotes and Swiss:P93653. Trehalose is a common disaccharide of bacteria, fungi and invertebrates that appears to play a major role in desiccation tolerance.

HAD-superfamily hydrolase, subfamily IIB; This subfamily falls within the Haloacid Dehalogenase (HAD) superfamily of aspartate-nucleophile hydrolases. The Class II subfamilies are characterized by a domain that is located between the second and third conserved catalytic motifs of the superfamily domain. The IIB subfamily is distinguished from the IIA subfamily (TIGR01460) by homology and the predicted secondary structure of this domain by PSI-PRED. The IIB subfamily's Class II domain has the following predicted structure: Helix-Sheet-Sheet-(Helix or Sheet)-Helix-Sheet-(variable)-Helix-Sheet-Sheet. The IIB subfamily consists of Trehalose-6-phosphatase (TIGR00685), plant and cyanobacterial Sucrose-phosphatase and a closely related group of bacterial and archaeal sequences, eukaryotic phosphomannomutase (pfam03332), a large subfamily ("Cof-like hydrolases", TIGR00099) containing many closely related bacterial sequences, a hypothetical equivalog containing the E. coli YedP protein, as well as two small clusters containing OMNI|TC0379 and OMNI|SA2196 whose relationship to the other groups is unclear.
