Functioni

Catalyzes the reversible interconversion of maltose and trehalose by transglucosylation. Maltose is the preferred substrate. To a lesser extent, also displays amylase activity, catalyzing the endohydrolysis of (1->4)-alpha-D-glucosidic linkages in glycogen and maltooligosaccharides such as maltoheptaose, to produce maltose which then can be converted to trehalose. TreS plays a key role in the utilization of trehalose for the production of glycogen, and might also function as a sensor and/or regulator of trehalose levels within the cell. Thus, when trehalose levels in the cell become dangerously low, TreS can expedite the conversion of glycogen to maltose via its amylase activity and then convert the maltose to trehalose; but this enzyme also can expedite or promote the conversion of trehalose to glycogen when cytoplasmic trehalose levels become too high. Is also able to catalyze the hydrolytic cleavage of alpha-aryl glucosides, as well as alpha-glucosyl fluoride in vitro.4 Publications

Catalytic activityi

Maltose = alpha,alpha-trehalose.1 Publication
Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units.1 Publication

Enzyme regulationi

The amylase activity is stimulated by addition of Ca2+, but this cation and other divalent cations inhibit the trehalose synthase activity. In addition, trehalose synthase activity, but not amylase activity, is strongly inhibited, and in a competitive manner, by validoxylamine. On the other hand, amylase, but not trehalose synthase activity, is inhibited by the known transition-state amylase inhibitor, acarbose, suggesting the possibility of two different active sites. Other metal ions such as Mg2+, Mn2+, and Co2+ are also somewhat effective in the stimulation of amylase activity, but Hg2+, Cu2+, Ni2+ and Zn2+ are inhibitory.3 Publications

  2. KM=87 mM for trehalose (at pH 6.8 and at 37 degrees Celsius)

  4. KM=2.5 mM for 3,4-dinitrophenyl alpha-D-glucoside (at pH 6.8 and 37 degrees Celsius)
  5. KM=2.2 mM for 4-chloro-2-nitrophenyl alpha-D-glucoside (at pH 6.8 and 37 degrees Celsius)

  8. KM=0.15 mM for alpha-glucosyl fluoride (at pH 6.8 and 37 degrees Celsius)

pH dependencei

Optimum pH is between 6.0-6.2 for the amylase activity and 7.0 for the trehalose synthase activity.
