|treC||Hydrolyzes trehalose-6-phosphate to glucose and glucose 6- phosphate. Can also very effectively hydrolyzes p-nitrophenyl-alpha-D- glucopyranoside, but it does not recognize trehalose, sucrose, maltose, isomaltose, or maltodextrins (551 aa)|| |
Predicted Functional Partners:
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in trehalose transport at low osmolarity.
| || || ||0.999
Catalyzes the transfer of glucose from UDP-alpha-D-glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose-6- phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor. Essential for viability of the cells at low temperatures and at elevated osmotic strength.
| || || || || ||0.982
Removes the phosphate from trehalose 6-phosphate (Tre6P) to produce free trehalose. Also catalyzes the dephosphorylation of glucose-6-phosphate (Glu6P) and 2-deoxyglucose-6-phosphate (2dGlu6P).
| || || || || ||0.980
Hydrolyzes trehalose to glucose. Could be involved, in cells returning to low osmolarity conditions, in the utilization of the accumulated cytoplasmic trehalose, which was synthesized in response to high osmolarity
| || || || || ||0.970
Provides the cells with the ability to utilize trehalose at high osmolarity by splitting it into glucose molecules that can subsequently be taken up by the phosphotransferase-mediated uptake system
| || || || || ||0.960
Repressor of the treBC operon. It is able to bind trehalose- 6-phosphate and trehalose
| || || || ||0.949
The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane . The enzyme II complex composed of PtsG and Crr is involved in glucose transport . The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc, however, may be an activator for adenylate cyclase. It is an important regulatory protein for cell metaboli [...]
| || || ||0.918
Not highly important in E.coli as glucose is transported into the cell by the PTS system already as glucose 6-phosphate
| || || || || ||0.905
Catalyzes the formation of the alpha-1,6-glucosidic linkages in glycogen by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position
| || || || ||0.802
Belongs to the disproportionating enzyme family.
