α,α-trehalose (ECMDB24256) (M2MDB006373)

General function:

Involved in catalytic activity

Specific function:

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

Gene Name:

treA

Uniprot ID:

P13482

Molecular weight:

63636

Reactions

General function:

Involved in catalytic activity

Specific function:

Removes the phosphate from trehalose 6-phosphate to produce free trehalose

Gene Name:

otsB

Uniprot ID:

P31678

Molecular weight:

29175

Reactions

General function:

Involved in protein-N(PI)-phosphohistidine-sugar phosphotransferase activity

Specific function:

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

Gene Name:

treB

Uniprot ID:

P36672

Molecular weight:

51080

Reactions

General function:

Involved in catalytic activity

Specific function:

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

Gene Name:

treF

Uniprot ID:

P62601

Molecular weight:

63696

Reactions

General function:

Involved in sugar:hydrogen symporter activity

Specific function:

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 glucose transport

Gene Name:

crr

Uniprot ID:

P69783

Molecular weight:

18251

Reactions

General function:

Involved in catalytic activity

Specific function:

Hydrolyzes the alpha-1,6-glucosidic linkages in glycogen which has first been partially depolymerized by phosphorylase. Shows only very little activity with native glycogen

Gene Name:

glgX

Uniprot ID:

P15067

Molecular weight:
