Psychiatry related information on Turanose

5. JHGase I showed unusual kinetic features: the negative cooperative behavior on the intrinsic reaction on cleavage of sucrose, maltose, and p-nitrophenyl alpha-glucoside, and the positive cooperative behavior on turanose [1].

High impact information on Turanose

In addition, turanose and alpha-methylglucoside induced small but significant inward currents indicating that they were transported by At-SUC2 [2].
In the turanose complex, the binding site of the first molecule in the asymmetric unit contains the alphaGlc1-3betaFruf form of furanose while the second molecule contains the alphaGlc1-3betaFrup form in its binding site [3].
We found that WOX5 is both turanose- and auxin-inducible [4].
Turanose-treated seedlings are characterized by a very short primary root and a short hypocotyl showing the production of adventitious roots [4].
Lactulose (beta-galactose [Gal][1-->4]Fru), palatinose (Glc[1-->6]Fru), and turanose (Glc[1-->3]Fru) are not metabolized but repress alpha-amylase [5].

Biological context of Turanose

A turanose-insensitive mutant suggests a role for WOX5 in auxin homeostasis in Arabidopsis thaliana [4].
AtSUC9 showed low substrate specificity, similar to AtSUC2 (At1g22710), and transported a wide range of glucosides, including helicin, salicin, arbutin, maltose, fraxin, esculin, turanose, and alpha-methyl-d-glucose [6].
Turanose has a noncompetitive inhibitory effect on the hydrolysis of maltose [7].

Anatomical context of Turanose

The agglutination of erythrocytes from the human O Rhesus positive blood group by sandfly midgut extracts was inhibited by two disaccharides; trehalose and turanose [8].

Associations of Turanose with other chemical compounds

More rigorous conditions resulted in the specific hydrolysis of one glycosidic bond in the tetrasaccharides derived from palatinose, leucrose and turanose, to yield spirodioxanyl trisaccharides [9].
Refeeding diets containing fructose (sucrose, turanose, melezitose, and monosaccharide equivalents containing fructose) increased the responses of G6PD, ME, FAS, and TLL [10].

Gene context of Turanose

The acid alpha-glucosidase enzymatic activity was determined at pH 4.0 in 0.1 mol/L Tris reagent, whereas the renal isoenzyme activity was determined at pH 5.6 in presence of 0.05 mol/L turanose reagent [11].
